Chapter 2
Safeguarding Your Network
For a wireless connection, the SSID, also called the wireless network name, and the wireless
security setting must be the same for the wireless router and wireless computers or wireless
adapters. NETGEAR strongly recommends that you use wireless security.
This chapter includes:
•“Planning Your Wireless Network”
•“Manually Configuring Your Wireless Settings” on page 2-4
•“Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-13
•“Connecting Additional Wireless Client Devices After WPS Setup” on page 2-18
•“Restricting Access to Your Router” on page 2-20
Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
To configure the wireless network, you can either specify the wireless settings, or you can use Wi-
Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.
• To manually configure the wireless settings, you must know the following:
– SSID. The default SSID for the wireless router is NETGEAR.
Warning: Computers can connect wirelessly at a range of several hundred feet. This can
allow others outside of your immediate area to access your network.
Note: For information about restricting access to USB storage devices, see “Configuring
USB Storage Advanced Settings” on page 7-7.

– The wireless radio frequency (2.4GHz or 5GHz) that each wireless adapter supports.
– Wireless security option. To successfully implement wireless security, check each
wireless adapter to determine which wireless security option it supports.
See “Manually Configuring Your Wireless Settings” on page 2-4.
• Push 'N' Connect (WPS) automatically implements wireless security on the wireless router
while, at the same time, allowing you to automatically implement wireless security on any
WPS-enabled devices (such as wireless computers and wireless adapter cards). You activate
WPS by pressing a WPS button on the wireless router, clicking an onscreen WPS button, or
entering a PIN number. This generates a new SSID and implements WPA/WPA2 security.
To set up your wireless network using the WPS feature:
– Use the WPS button on the side of the wireless router (there is also an onscreen WPS
button), or enter the PIN of the wireless device.
– Make sure that all wireless computers and wireless adapters on the network are Wi-Fi
certified and WPA or WPA 2 capable, and that they support WPS configuration.
See “Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-13.
Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the wireless router. The latency, data throughput performance, and notebook power consumption
of wireless adapters also vary depending on your configuration choices.
For best results, place your wireless router according to the following guidelines:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-
sight access (even if through walls).
• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup
(WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-
Fi-certified and WPS-capable products should be compatible with NETGEAR
products that implement Push 'N' Connect.

• Put the router in a vertical position to provide the best side-to-side coverage. Put the router in a
horizontal position to provide the best up-and-down coverage.
• If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Wireless Security Options
Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300
feet. Such distances can allow for others outside your immediate area to access your network.
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The WNDR3700 router provides highly effective security features which
are covered in detail in this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
•WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.
•WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise.

Using Push 'N' Connect (WPS) to Configure Your Wireless
Network
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure
the wireless router’s SSID and security settings and, at the same time, connect the wireless client
securely and easily to the wireless router. Look for the symbol on your client device
(computers that will connect wirelessly to the wireless router are clients). WPS automatically
configures the network name (SSID) and wireless security settings for the wireless router (if the
wireless router is in its default state) and broadcasts these settings to the wireless client.
Some considerations regarding WPS are:
• WPS supports these types of wireless security: None, WPA-PSK, WPA2-PSK, and WEP (with
the authentication type set to Automatic on the Wireless Settings screen). WEP security with
shared key authentication is not supported by WPS.
• If your wireless network will include a combination of WPS capable devices and non-WPS
capable devices, NETGEAR suggests that you set up your wireless network and security
settings manually first, and use WPS only for adding additional WPS capable devices. See
“Adding Both WPS and Non-WPS Clients” on page 2-18.
A WPS client can be added using the Push Button method or the PIN method.
•Using the Push Button. This is the preferred method. See the following section, “Using a
WPS Button to Add a WPS Client” on page 2-14.
•Entering a PIN. For information about using the PIN method, see “Using PIN Entry to Add a
WPS Client” on page 2-15.
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup
(WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-Fi-
certified and WPS-capable products should be compatible with NETGEAR
products that implement Push 'N' Connect.

Using a WPS Button to Add a WPS Client
Any wireless computer or wireless adapter that will connect to the wireless router wirelessly is a
client. The client must support a WPS button, and must have a WPS configuration utility, such as
the NETGEAR Smart Wizard or Atheros Jumpstart.
To use the wireless router WPS button to add a WPS client:
1. Log in to the wireless router at its default LAN address of http://www.routerlogin.net with
its default user name of admin and default password of password, or using whatever LAN
address and password you have set up.
2. On the wireless router main menu, select Add a WPS Client, and then click Next. The
following screen displays:
By default, the Push Button (recommended) radio button is selected.
3. Either press the WPS button on the side of the wireless router, or click the onscreen button.
The wireless router tries to communicate with the client for 2 minutes.
4. Go to the client wireless computer, and run a WPS configuration utility. Follow the utility’s
instructions to click a WPS button.
5. Go back to the wireless router screen to check for a message.

The wireless router WPS screen displays a message confirming that the client was added to the
wireless network. The wireless router generates an SSID, and implements WPA/WPA2
wireless security. The wireless router will keep these wireless settings unless you change
them, or you clear the Keep Existing Wireless Settings check box in the WPS Settings
screen.
6. Note the new SSID and WPA/WPA2 password for the wireless network. You can view these
settings in the Wireless Settings screen. See “Manually Configuring Your Wireless Settings”
on page 2-4.
To access the Internet from any computer connected to your wireless router, launch a browser such
as Microsoft Internet Explorer or Mozilla Firefox. You should see the wireless router’s Internet
LED blink, indicating communication to the ISP.
Using PIN Entry to Add a WPS Client
Any wireless computer or wireless adapter that will connect to the wireless router wirelessly is a
client. The client must support a WPS PIN, and must have a WPS configuration utility, such as the
NETGEAR Smart Wizard or Atheros Jumpstart.
The first time you add a WPS client, make sure that the Keep Existing Wireless Settings check
box on the WPS Settings screen is cleared. This is the default setting for the wireless router, and
allows it to generate the SSID and WPA/WPA2 security settings when it implements WPS. After
WPS is implemented, the wireless router automatically selects this check box so that your SSID
and wireless security settings remain the same if other WPS-enabled devices are added later.
Figure 2-6
Note: If no WPS-capable client devices are located during the 2-minute time frame, the
SSID will not be changed, and no security will be implemented on the wireless
router.

•“Setting the Time” on page 3-11
Protecting Access to Your Wireless Router
For security reasons, the wireless router has its own user name and password. Also, after a period
of inactivity for a set length of time, the administrator login automatically disconnects. When
prompted, enter admin for the wireless router user name and password for the wireless router
password. You can use procedures in the following sections to change the wireless router
password and the amount of time for the administrator’s login time-out.
NETGEAR recommends that you change this password to a more secure password. The ideal
password should contain no dictionary words from any language, and should be a mixture of both
upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.
Note: The user name and password are not the same as a user name or password you
might use to log in to your Internet connection.

4. Click Apply to save your changes.
Restricting Access by MAC Address
For increased security, you can restrict access to the wireless network to allow only specific PCs
based on their MAC addresses. You can restrict access to only trusted PCs so that unknown PCs
cannot wirelessly connect to the WNDR3700 router. MAC address filtering adds an obstacle
against unwanted access to your network, but the data broadcast over the wireless link is fully
exposed.
To restrict access based on MAC addresses:
1. Log in to the wireless router at its default LAN address of http://www.routerlogin.net with
its default user name of admin, and default password of password, or using whatever
password and LAN address you have chosen for the wireless router.
Note: After changing the password, you must log in again to continue the
configuration. If you have backed up the wireless router settings previously,
you should do a new backup so that the saved settings file includes the new
password.
Note: If you configure the router from a wireless computer, add your computer’s
MAC address to the access list. Otherwise you will lose your wireless
connection when you click Apply. You must then access the wireless router
from a wired computer, or from a wireless computer that is on the access
control list, to make any further changes.

4. You can specify one trusted user, which is a computer that is exempt from blocking and
logging. Specify a trusted user by entering that computer’s IP address in the Trusted IP
Address fields.
Since the trusted user is identified by IP address, you should configure that computer with a
fixed IP address.
5. Click Apply to save all your settings in the Block Sites screen.
Blocking Access to Internet Services
The wireless router allows you to block the use of certain Internet services by computers on your
network. This is called service blocking or port filtering. Services are functions performed by
server computers at the request of client computers. For example, Web servers serve Web pages,
time servers serve time and date information, and game hosts serve data about other players’
moves. When a computer on your network sends a request for service to a server computer on the
Internet, the requested service is identified by a service or port number. This number appears as the
destination port number in the transmitted IP packets. For example, a packet that is sent with
destination port number 80 is an HTTP (Web server) request.

Configuring a User-Defined Service
To define a service, first you must determine which port number or range of numbers is used by
the application. The service port numbers for many common protocols are defined by the Internet
Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service
numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of
the application. You can often determine port number information by contacting the publisher of
the application, by asking user groups or newsgroups, or by searching.
• Enter the starting port and ending port numbers. If the application uses a single port number,
enter that number in both fields.
• If you know that the application uses either TCP or UDP, select the appropriate protocol. If
you are not sure, select Both.

The router is shipped preconfigured to use private IP addresses on the LAN side and to act as a
DHCP server. The router’s default LAN IP configuration is:
• LAN IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
These addresses are part of the designated private address range for use in private networks and
should be suitable for most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in the LAN Setup screen.

IP Address The LAN IP address of the wireless router.
IP Subnet Mask The LAN subnet mask of the wireless router. Combined
with the IP address, the IP Subnet Mask allows a device to
know which other addresses are local to it, and which must
be reached through a gateway or wireless router.
RIP Direction RIP (Router Information Protocol) allows a wireless router
to exchange routing information with other routers. This
setting controls how the wireless router sends and receives
RIP packets. Both is the default.
•Both or Out Only. The wireless router broadcasts its
routing table periodically.
•Both or In Only. The wireless router incorporates the RIP
information that it receives.
RIP Version This controls the format and the broadcasting method of the
RIP packets that the wireless router sends. It recognizes
both formats when receiving. By default, the RIP function is
disabled.
• RIP-1 is universally supported. It is adequate for most
networks, unless you have an unusual network setup.
• RIP-2 carries more information. Both RIP-2B and RIP-2M
send the routing data in RIP-2 format. RIP-2B uses
subnet broadcasting. RIP-2M uses multicasting.

Using the Router as a DHCP Server
By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default
gateway addresses to all computers connected to the router’s LAN. The assigned default gateway
address is the LAN address of the router. The router assigns IP addresses to the attached computers
from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to
avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. Click
the link to the online document “TCP/IP Networking Basics” in Appendix B for an explanation of
DHCP and information about how to assign IP addresses for your network.
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP
address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.1.2 and
192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the router’s LAN IP address)
• Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen;
otherwise, the router’s LAN IP address)
• Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings screen)
To use another device on your network as the DHCP server, or to manually configure the network
settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise,
leave it selected. If this service is not selected and no other DHCP server is available on your
network, you will need to set your computers’ IP addresses manually or they will not be able to
access the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router’s DHCP server. Reserved IP
addresses should be assigned to computers or servers that require permanent IP settings.
To reserve an IP address:
1. Click Add.

address from the router’s LAN subnet, such as 192.168.1.x.)
3. Type the MAC address of the computer or server.
4. Click Apply to enter the reserved address into the table.
To edit or delete a reserved address entry:
1. Select the radio button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.
Using a Dynamic DNS Service
If your Internet Service Provider (ISP) gave you a permanently assigned IP address, you can
register a domain name and have that name linked with your IP address by public Domain Name
Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you do
not know in advance what your IP address will be, and the address can change frequently. In this
case, you can use a commercial Dynamic DNS service, which allows you to register your domain
to their IP address, and forwards traffic directed at your domain to your frequently changing IP
address.
Your router contains a client that can connect to the Dynamic DNS service provided by
DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host
name, which you configure in the router. Then, whenever your ISP-assigned IP address changes,
Tip: If the computer is already present on your network, you can copy its MAC
address from the Attached Devices screen and paste it here.
Note: The reserved address is not assigned until the next time the computer contacts
the router’s DHCP server. Reboot the computer or access its IP configuration
and force a DHCP release and renew.
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the
Dynamic DNS service will not work because private addresses are not routed on
the Internet.

your router automatically contacts the Dynamic DNS service provider, logs in to your account, and
registers your new IP address. If your host name is hostname, for example, you can reach your
router at hostname.dyndns.org.
From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS screen.
To configure Dynamic DNS:
1. Register for an account with one of the Dynamic DNS service providers whose names appear
in the Service Provider list. For example, for DynDNS.org, select www.dyndns.org.
2. Select the Use a Dynamic DNS Service check box.
3. Select the name of your Dynamic DNS service provider.
4. Type the host name (or domain name) that your Dynamic DNS service provider gave you.
5. Type the user name for your Dynamic DNS account. This is the name that you use to log in to
your account, not your host name.
6. Type the password (or key) for your Dynamic DNS account.
7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can
select the Use Wildcards check box to activate this feature.
For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org.

Setting Description
Disable SPI Firewall The Stateful Packet Inspection (SPI) firewall protects your network and
computers against attacks and intrusions. A stateful packet firewall carefully
inspects incoming traffic packets, looking for known exploits such as
malformed, oversized, or out-of-sequence packets. The firewall should be
disabled only in special circumstances, such as when you are troubleshooting
application issues.
Default DMZ Server This feature is sometimes helpful when you are using some online games and
videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See the following section, Configuring Static
Routes.
Respond to Ping on Internet

If you want the wireless router to respond to a ping from the Internet, select
this check box. This should be used only as a diagnostic tool, since it allows
your wireless router to be discovered. Do not select this check box unless you
have a specific reason to do so.
MTU Size (in bytes) The normal MTU (Maximum Transmit Unit) value for most Ethernet networks
is 1500 bytes, or 1492 Bytes for PPPoE connections. For some ISPs you
might need to reduce the MTU. This is rarely required, and should not be done
unless you are sure it is necessary for your ISP connection. See “Changing
the MTU Size” on page 6-6.

v1.3, October 2009
Setting Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation (NAT).
The router is programmed to recognize some of these applications and to work correctly with
them, but there are other applications that might not function well. In some cases, one local
computer can run the application correctly if that computer’s IP address is entered as the default
DMZ server.
Incoming traffic from the Internet is usually discarded by the router unless the traffic is a response
to one of your local computers or a service that you have configured in the Port Forwarding/Port
Triggering screen. Instead of discarding this traffic, you can have it forwarded to one computer on
your network. This computer is called the default DMZ server.
The WAN Setup screen lets you configure a default DMZ server.
To assign a computer or server to be a default DMZ server:
1. Click the Default DMZ Server check box.
2. Type the IP address.
NAT Filtering Network Address Translation (NAT) determines how the router processes
inbound traffic. Secured NAT provides a secured firewall to protect the
computers on the LAN from attacks from the Internet, but might prevent some
Internet games, point-to-point applications, or multimedia applications from
functioning. Open NAT provides a much less secured firewall, but allows
almost all Internet applications to function.
Disable SIP ALG Select this feature if you have a SIP (Session Initiation Protocol) telephone or
other SIP base devices, and you want them to communicate with other
people. If you have been unable to build a successful SIP connection,
selecting this check box allows for such a connection without compromising
other SIP ALG (Application-level gateway) firewall settings, such as Disable
SPI Firewall. If you are not using SIP devices, leave this check box
unchecked.
Warning: DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall and is exposed to exploits
from the Internet. If compromised, the DMZ server computer can be used to
attack other computers on your network.

3. Click Apply.
Configuring Static Routes
Static routes provide additional routing information to your router. Under usual circumstances, the
router has adequate routing information after it has been configured for Internet access, and you do
not need to configure additional static routes. You must configure static routes only for unusual
cases such as multiple routers or multiple IP subnets located on your network.
As an example of when a static route is needed, consider the following case:
• Your primary Internet access is through a cable modem to an ISP.
• You have an ISDN router on your home network for connecting to the company where you are
employed. This router’s address on your LAN is 192.168.1.100.
• Your company’s network address is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the gateway, and a second static route was created to your local network
for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on the
134.177.0.0 network, your router forwards your request to the ISP. The ISP forwards your request
to the company where you are employed, and the request is likely to be denied by the company’s
firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.1.100.
In this example:
• The Destination IP Address and IP Subnet Mask fields specify that this static route applies
to all 134.177.x.x addresses.
• The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.1.100.
•A Metric value of 1 will work since the ISDN router is on the LAN.
•Private is selected only as a precautionary security measure in case RIP is activated.

Allowing Inbound Connections to Your Network
By default, the WNDR3700 router blocks any inbound traffic from the Internet to your computers
except for replies to your outbound traffic. However, you might need to create exceptions to this
rule for the following purposes:
• To allow remote computers on the Internet to access a server on your local network.
• To allow certain applications and games to work correctly when their replies are not
recognized by your router.
Your router provides two features for creating these exceptions: port forwarding and port
triggering. This section explains how a normal outbound connection works, followed by two
examples explaining how port forwarding and port triggering operate and how they differ.
How Your Computer Accesses a Remote Computer through Your
Router
When a computer on your network needs to access a computer on the Internet, your computer
sends your router a message containing source and destination address and process information.
Before forwarding your message to the remote computer, your router must modify the source
information and must create and track the communication session so that replies can be routed
back to your computer.
Here is an example of normal outbound traffic and the resulting inbound responses:
1. You open Internet Explorer, beginning a browser session on your computer. Invisible to you,
your operating system assigns a service number (port number) to every communication
process running on your computer. In this example, let’s say Windows assigns port number
5678 to this browser session.
2. You ask your browser to get a Web page from the Web server at www.example.com. Your
computer composes a Web page request message with the following address and
port information:
• The source address is your computer’s IP address.
• The source port number is 5678, the browser session.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual
Customizing Your Network Settings 5-12
v1.3, October 2009
• The destination address is the IP address of www.example.com, which your computer
finds by asking a DNS server.
• The destination port number is 80, the standard port number for a Web server process.
Your computer then sends this request message to your router.
3. Your router creates an entry in its internal session table describing this communication session
between your computer and the Web server at www.example.com. Before sending the Web
page request message to www.example.com, your router stores the original information and
then modifies the source information in the request message, performing Network Address
Translation (NAT):
• The source address is replaced with your router’s public IP address.
This is necessary because your computer uses a private IP address that is not globally
unique and cannot be used on the Internet.
• The source port number is changed to a number chosen by the router, such as 33333. This
is necessary because two computers could independently be using the same session
number.
Your router then sends this request message through the Internet to the Web server at
www.example.com.
4. The Web server at www.example.com composes a return message with the requested Web
page data. The return message contains the following address and port information:
• The source address is the IP address of www.example.com.
• The source port number is 80, the standard port number for a Web server process.
• The destination address is the public IP address of your router.
• The destination port number is 33333.
The Web server then sends this reply message to your router.
5. Upon receiving the incoming message, your router checks its session table to determine
whether there is an active session for port number 33333. Finding an active session, the router
then modifies the message, restoring the original address information replaced by NAT. The
message now contains the following address and port information:
• The source address is the IP address of www.example.com.
• The source port number is 80, the standard port number for a Web server process.
• The destination address is your computer’s IP address.
• The destination port number is 5678, the browser session that made the initial request.

Customizing Your Network Settings 5-13
v1.3, October 2009
Your router then sends this reply message to your computer, which displays the Web page
from www.example.com.
6. When you finish your browser session, your router eventually senses a period of inactivity in
the communications. Your router then removes the session information from its session table,
and incoming traffic is no longer accepted on port number 33333.
How Port Triggering Changes the Communication Process
In the preceding example, requests are sent to a remote computer by your router from a particular
service port number, and replies from the remote computer to your router are directed to that port
number. If the remote server sends a reply back to a different port number, your router will not
recognize it and will discard it. However, some application servers (such as FTP and IRC servers)
send replies back to multiple port numbers. Using the port triggering function of your router, you
can tell the router to open additional incoming ports when a particular outgoing port originates
a session.
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination
port 6667. The IRC server not only responds to your originating source port, but also sends an
“identify” message to your computer on port 113. Using port triggering, you can tell the router,
“When you initiate a session with destination port 6667, you must also allow incoming traffic on
port 113 to reach the originating computer.” Using steps similar to the preceding example, the
following sequence shows the effects of the port triggering rule you have defined:
1. You open an IRC client program, beginning a chat session on your computer.
2. Your IRC client composes a request message to an IRC server using a destination port number
of 6667, the standard port number for an IRC server process. Your computer then sends this
request message to your router.
3. Your router creates an entry in its internal session table describing this communication session
between your computer and the IRC server. Your router stores the original information,
performs Network Address Translation (NAT) on the source address and port, and sends this
request message through the Internet to the IRC server.
4. Noting your port triggering rule, and having observed the destination port number of 6667,
your router creates an additional session entry to send any incoming port 113 traffic to your
computer.
5. The IRC server sends a return message to your router using the NAT-assigned source port (as
in the previous example, let’s say port 33333) as the destination port. The IRC server also
sends an “identify” message to your router with destination port 113.

Customizing Your Network Settings 5-14
v1.3, October 2009
6. Upon receiving the incoming message to destination port 33333, your router checks its session
table to determine whether there is an active session for port number 33333. Finding an active
session, the router restores the original address information replaced by NAT and sends this
reply message to your computer.
7. Upon receiving the incoming message to destination port 113, your router checks its session
table and learns that there is an active session for port 113, associated with your computer. The
router replaces the message’s destination IP address with your computer’s IP address and
forwards the message to your computer.
8. When you finish your chat session, your router eventually senses a period of inactivity in the
communications. The router then removes the session information from its session table, and
incoming traffic is no longer accepted on port numbers 33333 or 113.
To configure port triggering, you need to know which inbound ports the application needs. Also,
you need to know the number of the outbound port that will trigger the opening of the inbound
ports. You can usually determine this information by contacting the publisher of the application, or
user groups or newsgroups.
How Port Forwarding Changes the Communication Process
In both of the preceding examples, your computer initiates an application session with a server
computer on the Internet. However, you might need to allow a client computer on the Internet to
initiate a connection to a server computer on your network. Normally, your router ignores any
inbound traffic that is not a response to your own outbound traffic. You can configure exceptions
to this default rule by using the port forwarding feature.
A typical application of port forwarding can be shown by reversing the client-server relationship
from our previous Web server example. In this case, a remote computer’s browser needs to access
a Web server running on a computer in your local network. Using port forwarding, you can tell the
router, “When you receive incoming traffic on port 80 (the standard port number for a Web server
process), forward it to the local computer at 192.168.1.123.” The following sequence shows the
effects of the port forwarding rule you have defined:
1. The user of a remote computer opens Internet Explorer and requests a Web page from
www.example.com, which resolves to the public IP address of your router. The remote
computer composes a Web page request message with the following destination information:
Note: Only one computer at a time can use the triggered application.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual
Customizing Your Network Settings 5-15
v1.3, October 2009
• The destination address is the IP address of www.example.com, which is the address of
your router.
• The destination port number is 80, the standard port number for a Web server process.
The remote computer then sends this request message through the Internet to your router.
2. Your router receives the request message and looks in its rules table for any rules covering the
disposition of incoming port 80 traffic. Your port forwarding rule specifies that incoming port
80 traffic should be forwarded to local IP address 192.168.1.123. Therefore, your router
modifies the destination information in the request message:
The destination address is replaced with 192.168.1.123.
Your router then sends this request message to your local network.
3. Your Web server at 192.168.1.123 receives the request and composes a return message with
the requested Web page data. Your Web server then sends this reply message to your router.
4. Your router performs Network Address Translation (NAT) on the source IP address, and sends
this request message through the Internet to the remote computer, which displays the Web
page from www.example.com.
To configure port forwarding, you need to know which inbound ports the application needs. You
usually can determine this information by contacting the publisher of the application or user
groups or newsgroups.
How Port Forwarding Differs from Port Triggering
The following points summarize the differences between port forwarding and port triggering:
• Port triggering can be used by any computer on your network, although only one computer can
use it at a time.
• Port forwarding is configured for a single computer on your network.
• Port triggering does not need to know the computer’s IP address in advance. The IP address is
captured automatically.
• Port forwarding requires that you specify the computer’s IP address during configuration, and
the IP address must never change.
• Port triggering requires specific outbound traffic to open the inbound ports, and the triggered
ports are closed after a period of no activity.
• Port forwarding is always active and does not need to be triggered.

Configuring Port Forwarding to Local Servers
Using the port forwarding feature, you can allow certain types of incoming traffic to reach servers
on your local network. For example, you might make a local Web server, FTP server, or game
server visible and available to the Internet.
Use the Port Forwarding screen to configure the router to forward specific incoming protocols to
computers on your local network. In addition to servers for specific applications, you can also
specify a default DMZ server to which all other incoming protocols are forwarded. The DMZ
server is configured in the WAN Setup screen, as discussed in “Setting Up a Default DMZ Server”
on page 5-8.
Before starting, you need to determine which type of service, application, or game you will
provide, and the local IP address of the computer that will provide the service. Be sure the
computer’s IP address never changes.
To configure port forwarding to a local server:
1. Select Port Forwarding/Port Triggering under Advanced in the main menu.
2. Select the Port Forwarding radio button as the Service type.
Tip: To ensure that your server computer always has the same IP address, use the
reserved IP address feature of your WNDR3700 router. See “Address Reservation”
on page 5-4 for instructions on how to use reserved IP addresses.

computer that will provide this service.
5. Click Add. The service appears in the list in the screen.
Adding a Custom Service
To define a service, game, or application that does not appear in the Service Name list, you must
first determine which port number or range of numbers is used by the application. You can usually
determine this information by contacting the publisher of the application or user groups or
newsgroups. When you have the port number information, follow these steps:
1. Select Port Forwarding/Port Triggering under Advanced in the main menu.
2. Select the Port Forwarding radio button as the Service type.
3. Click Add Custom Service.
4. In the Service Name field, enter a descriptive name.
5. In the Protocol field, select the protocol. If you are unsure, select TCP/UDP.
6. In the Starting Port field, enter the beginning port number.
• If the application uses only a single port, enter the same port number in the Ending Port
field.

• If the application uses a range of ports, enter the ending port number of the range in the
Ending Port field.
7. In the Server IP Address field, enter the IP address of your local computer that will provide
this service.
8. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen.
Editing or Deleting a Port Forwarding Entry
To edit or delete a port forwarding entry:
1. In the table, select the button next to the service name.
2. Click Edit Service or Delete Service.
Application Example: Making a Local Web Server Public
If you host a Web server on your local network, you can use port forwarding to allow Web
requests from anyone on the Internet to reach your Web server.
To make a local Web server public:
1. Assign your Web server either a fixed IP address or a dynamic IP address using DHCP address
reservation, as explained in “Address Reservation” on page 5-4. In this example, your router
will always give your Web server an IP address of 192.168.1.33.
2. In the Port Forwarding screen, configure the router to forward the HTTP service to the local
address of your Web server at 192.168.1.33.
HTTP (port 80) is the standard protocol for Web servers.
3. (Optional) Register a host name with a Dynamic DNS service, and configure your router to
use the name as described in “Using a Dynamic DNS Service” on page 5-5.
To access your Web server from the Internet, a remote user must know the IP address that has
been assigned by your ISP. However, if you use a Dynamic DNS service, the remote user can
reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.
Configuring Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
• More than one local computer needs port forwarding for the same application (but not
simultaneously).
• An application needs to open incoming ports that are different from the outgoing port.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual
Customizing Your Network Settings 5-19
v1.3, October 2009
When port triggering is enabled, the router monitors outbound traffic looking for a specified
outbound “trigger” port. When the router detects outbound traffic on that port, it remembers the IP
address of the local computer that sent the data. The router then temporarily opens the specified
incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering
computer.
While port forwarding creates a static mapping of a port number or range to a single local
computer, port triggering can dynamically open ports to any computer that needs them and can
close the ports when they are no longer needed.
To configure port triggering, you need to know which inbound ports the application needs. Also,
you need to know the number of the outbound port that will trigger the opening of the inbound
ports. You can usually determine this information by contacting the publisher of the application or
user groups or newsgroups.
To set up port triggering:
1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The
Forwarding/Port Triggering screen displays.
Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should also enable Universal Plug and Play (UPnP) according
to the instructions in “Universal Plug and Play” on page 6-13.

Wireless Repeating (Also Called WDS)
The WNDR3700 router can be used with a wireless access point (AP) to build large bridged
wireless networks. Wireless repeating is a type of Wireless Distribution System (WDS).
The following figure shows a wireless repeating scenario:
To set up a wireless network using WDS, the following conditions must be met for both APs:
• Both APs must use the same SSID, wireless channel, and encryption mode (see “Manually
Configuring Your Wireless Settings” on page 2-4 or “Using Push 'N' Connect (WPS) to
Configure Your Wireless Network” on page 2-13).
• Both APs must be on the same LAN IP subnet. That is, all the AP LAN IP addresses are in the
same network.
• All LAN devices (wired and wireless computers) must be configured to operate in the same
LAN network address range as the APs.
Warning: If you use the wireless repeating function, your options for wireless security
are limited to None or WEP. For more information about wireless security, see
Chapter 2, “Safeguarding Your Network.”

You can view or change wireless repeater settings for the wireless router. From the main menu of
the browser interface, under Advanced, click Wireless Repeating Function to display the
Wireless Repeating Function screen.
For each wireless radio (2.4GHz and 5GHz), the wireless router supports two modes of the
wireless repeating function, and allows you to control wireless client association:
•Wireless Repeater. The wireless router sends all traffic from its local wireless or wired
computers to a remote AP. To configure this mode, you must know the MAC address of the
remote parent AP.
•Wireless Base Station. The wireless router acts as the parent AP, bridging traffic to and from
the child repeater AP, as well as handling wireless and wired local computers. To configure
this mode, you must know the MAC addresses of the child repeater AP.
•Disable Wireless Client Association. Usually this check box is cleared so that the router is an
access point for wireless computers.

If this check box is selected, the router communicates wirelessly only with other APs whose MAC
addresses are listed in this screen. The router still communicates with wire-connected LAN
devices.
Setting Up the Base Station
The wireless repeating function works only in hub and spoke mode. The units cannot be daisy
chained. You must know the wireless settings for both units. You must know the MAC address of
the remote unit. First, set up the base station, and then set up the repeater. To set up the base
station:
1. Set up both units with exactly the same wireless settings (SSID, mode, channel, and security).
Note that the wireless security option must be set to None or WEP.
Note: The WNDR3700 router is always in dual band concurrent mode, unless you turn
off one radio. Be aware that if you enable the wireless repeater in either radio band,
the wireless base station or wireless repeater cannot be enabled in the other radio
band. However, if you enable the wireless base station in either radio band and use
the other radio band as a wireless router or wireless base station, dual band
concurrent mode is not affected.

Chapter 6
Fine-Tuning Your Network
This chapter describes features to help you manage your RangeMax Dual Band Wireless-N
Gigabit Router WNDR3700.
This chapter includes the following sections:
•“Assessing Your Speed Requirements” on page 6-2
•“Optimizing Your Network Bandwidth” on page 6-3
•“Optimizing Wireless Performance” on page 6-5
•“Changing the MTU Size” on page 6-6
•“Quality of Service (QoS)” on page 6-7
Common connection types and their speed and security considerations are:
•Broadband Internet. Your Internet connection speed is determined by your modem type,
such as ADSL or cable modem, as well as the connection speed of the sites to which you
connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical,
meaning they have a lower data rate to the Internet (upstream) than from the Internet
(downstream). Keep in mind that when you connect to another site that also has an
asymmetrical connection, the data rate between your sites is limited by each side’s upstream
data rate. A typical residential ADSL or cable modem connection provides a downstream
throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+
and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.
•Wireless. Your RangeMax Dual Band Wireless-N Gigabit Router WNDR3700 provides a
wireless data throughput of up to 300 Mbps using technology called multiple input, multiple
output (MIMO), in which multiple antennas transmit multiple streams of data. The use of
multiple antennas also provides excellent range and coverage. With the introduction of the
newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely
strong.
To get the best performance, use RangeMax adapters, such as the WNDA3100, for your
computers. Although the RangeMax router is compatible with older 802.11b and 802.11g
adapters, the use of these older wireless technologies in your network can result in lower
throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for
802.11g). In addition, many older wireless products do not support the latest security
protocols, WPA and WPA2.

•Powerline. For connecting rooms or floors that are blocked by obstructions or are distant
vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD
family of products delivers up to 200 Mbps to any outlet, while the older-generation XE
family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for
security, and you can configure an individual network password to prevent neighbors from
connecting.
The Powerline HD family of products can coexist on the same network with older-generation
XE family products or HomePlug 1.0 products, but they are not interoperable with these older
products.
•Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on
newer computers, wired Ethernet remains a good choice for speed, economy, and security.
Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A
wired connection is not susceptible to interference, and eavesdropping would require a
physical connection to your network.
Assessing Your Speed Requirements
Because your Internet connection is likely to operate at a much lower speed than your local
network, faster local networking technologies might not improve your Internet experience.
However, many emerging home applications require high data rates. For example:
• Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can
disrupt your video, plan to provide at least twice the capacity you need.
• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern
networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so
a congested network or a noisy link can cause problems.
Note: Actual data throughput will vary. Network conditions and environmental factors,
including volume of network traffic, building materials and construction, and
network overhead, can lower actual data throughput rate.

• Backing up computers over the network has become popular due to the availability of
inexpensive mass storage. Table 6-1 shows the time to transfer 1 gigabyte (GB) of data using
various networking technologies.
Optimizing Your Network Bandwidth
As your network grows, it might consist of several segments of different networking technologies,
each providing different throughput. In planning your network, you should first consider which
devices will have the heaviest traffic flow between them. Examples are:
• A media center in one room streaming high-definition video from a server in another room
• A storage device that is used for backing up your computers

Next, consider the throughput of your network devices. Where possible, make the heaviest-traffic
connections using higher-speed technologies, with no lower-speed bottlenecks in the path.
Figure 6-1 shows a sample network using multiple networking technologies. In this network, the
two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the GS605
switch to the storage server. This connection should allow for extremely fast backups or quick
access to large files on the server. The PC connected through a pair of Powerline HD adapters is
limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this
example would be sufficient for high-traffic applications such as streaming HD video, the use of
older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant bottleneck.

Optimizing Wireless Performance
The speed and operating distance or range of your wireless connection can vary significantly based
on the physical placement of the wireless router. You should choose a location for your router that
will maximize the network speed.
The following list describes how to optimize wireless router performance.
•Identify critical wireless links.
If your network has several wireless devices, decide which wireless devices need the highest
data rate, and locate the router near them. Many wireless products have automatic data-rate
fallback, which allows increased distances without loss of connectivity. This also means that
devices that are farther away might be slower. Therefore, the most critical links in your
network are those where the traffic is high and the distances are great. Optimize those first.
•Choose placement carefully.
For best results, place your router:
– Near the center of the area in which your computers will operate.
– In an elevated location such as a high shelf where the wirelessly connected computers
have line-of-sight access (even if through walls).
– Avoid obstacles to wireless signals.
– Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets,
refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.
– Keep away from large amounts of water such as fish tanks and water coolers.
• Reduce interference.
– Avoid windows unless communicating between buildings.
– Place wireless devices away from various electromagnetic noise sources, especially those
in the 2400–2500 MHz frequency band. Common noise-creating sources are:
• Computers and fax machines (no closer than 1 foot)
• Copying machines, elevators, and cell phones (no closer than 6 feet)
Note: Failure to follow these guidelines can result in significant performance degradation
or inability to wirelessly connect to the router. For complete range and
performance specifications, click the link to the online document “Wireless
Networking Basics” in Appendix B.

Fine-Tuning Your Network 6-6
v1.3, October 2009
• Microwave ovens (no closer than 10 feet)
• Choose your settings.
– Use a scanning utility to determine what other wireless networks are operating nearby, and
choose an unused channel.
– Turn off SSID broadcast, and change the default SSID. Other nearby devices might
automatically try to connect to your network several times a second, which can cause
significant performance reduction.
• Set WPA2-PSK (AES) security to achieve the best wireless performance and the best security.
• Use WMM to improve the performance of voice and video traffic over the wireless link.
Changing the MTU Size
The Maximum Transmission Unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets travel
through many devices along the way. If any device in the data path has a lower MTU setting than
the other devices, the data packets must be split or “fragmented” to accommodate the one with the
smallest MTU.
The best MTU setting for NETGEAR equipment is often just the default value, and changing the
value might fix one problem but cause another. Leave MTU unchanged unless one of these
situations occurs:
• You have problems connecting to your ISP or other Internet service, and the technical support
of either the ISP or NETGEAR recommends changing the MTU setting. These might require
an MTU change:
– A secure website that won’t open, or displays only part of a Web page
– Yahoo e-mail
– MSN
– America Online’s DSL service
• You use VPN and have severe performance problems.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual
Fine-Tuning Your Network 6-7
v1.3, October 2009
• You used a program to optimize MTU for performance reasons, and now you have
connectivity or performance problems.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are
willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until
the problem goes away. Table 6-2 describes common MTU sizes and applications.
To change the MTU size:
1. In the main menu, under Advanced, select WAN Setup.
2. In the MTU Size field, enter a new size between 64 and 1500.
3. Click Apply to save the new configuration.
Quality of Service (QoS)
QoS is an advanced feature that can be used to prioritize some types of traffic ahead of others. The
WNDR3700 router can provide QoS prioritization over the wireless link and on the Internet
connection. To configure QoS, use the QoS Setup screen.
Note: An incorrect MTU setting can cause Internet communication problems such as the
inability to access certain Web sites, frames within Web sites, secure login pages,
or FTP or POP servers.
Table 6-2. Common MTU Sizes
MTU Application
1500 The largest Ethernet packet size and the default value. This is the typical setting for non-
PPPoE, non-VPN connections, and is the default value for NETGEAR routers, adapters,
and switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you don't have large e-mail attachments, for example.
1436 Used in PPTP environments or with VPN.

From the main menu, under Advanced, select QoS Setup. The QoS Setup screen displays:
Using WMM QoS for Wireless Multimedia Applications
The WNDR3700 router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize
wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of
wireless data packets from different applications based on four access categories: voice, video,
best effort, and background. For an application to receive the benefits of WMM QoS, both it and
the client running that application must be WMM enabled. Legacy applications that do not support
WMM, and applications that do not require QoS, are assigned to the best effort category, which
receives a lower priority than voice and video.
WMM QoS is enabled by default. You can disable it in the QoS Setup screen, shown in
Figure 6-2 on page 6-8, by clearing the Enable WMM check box and clicking Apply.
Configuring QoS for Internet Access
You can give prioritized Internet access to the following types of traffic:
• For specific applications
• For specific online games
• On individual Ethernet LAN ports of the router
• From a specific device by MAC address

Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to
access the network and connect to other devices as needed. UPnP devices can automatically
discover the services from other registered UPnP devices on the network.
To turn on Universal Plug and Play:
1. From the main menu, under Advanced, click UPnP. The UPnP screen displays.
2. The available settings and information in this screen are:
•Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is disabled. If this check box is not selected, the router does
not allow any device to automatically control the resources, such as port forwarding
(mapping) of the router.
•Advertisement Period. The advertisement period is how often the router broadcasts its
UPnP information. This value can range from 1 to 1440 minutes. The default period is 30
minutes. Shorter durations ensure that control points have current device status at the
expense of additional network traffic. Longer durations might compromise the freshness
of the device status but can significantly reduce network traffic.
Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should enable UPnP.

•Advertisement Time To Live. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. The time to live hop count is the number of steps a
broadcast packet is allowed to propagate for each UPnP advertisement before it
disappears. The number of hops can range from 1 to 255. The default value for the
advertisement time to live is 4 hops, which should be fine for most home networks. If you
notice that some devices are not being updated or reached correctly, then it might be
necessary to increase this value.
•UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP
device that is currently accessing the router and which ports (Internal and External) that
device has opened. The UPnP Portmap Table also displays what type of port is open and
whether that port is still active for each IP address.

Actual bus speeds can vary, depending on the CPU speed, memory, speed of the network, and
other variables.
The router should work with most USB-compliant external flash and hard drives. For the most up-
to-date list of USB drives supported by the router, go to: http://kb.netgear.com/app/answers/detail/
/a_id/11280.
The router supports both READ and WRITE for FAT16, FAT32, NTFS, and Linux file systems
(EXT2 and EXT3).
File Sharing Scenarios
You can share files on the USB drive for a wide variety of business and recreational purposes. The
files can be any PC, Mac, or Linux file type including text files, Word, PowerPoint, Excel, MP3.
pictures, and multimedia. USB drive applications include:
• Sharing multimedia with friends and family—sharing MP3 files, pictures, and other
multimedia with local and remote users.
• Sharing resources on your network—storing files in a central location so that you do not have
to power up a computer to perform local sharing. In addition, you can share files between
Macintosh, Linux, and PC computers by using the USB drive as a go-between across the
systems.
• Sharing files with offsite coworkers—sharing files such as Word documents, PowerPoint
presentations, and text files with remote users.
A few common uses are described in the following sections.
Sharing Photos with Friends and Family
You can create your own central storage location for photos and multimedia. This eliminates the
need to log in to (and pay for) an external photo sharing site.
To share files with your friends and family:
1. Insert your USB drive into the USB port on the router either directly or with a USB cable.
Note: Some USB external hard drives and flash drives require drivers to be loaded in to
the PC before the PC can access the USB device. Such USB devices will not work
with the WNDR3700 router.

Computers on your local area network (LAN) can automatically access this USB drive using a
Web browser or Microsoft Networking.
2. If you want to specify read only access, or to allow access from the Internet, see “Configuring
USB Storage Advanced Settings” on page 7-7.
Storing Files in a Central Location for Printing
This scenario is for a family that has one high quality color printer directly attached to a PC, but
not shared on the local area network (LAN). This family does not have a print server:
• The daughter has some photos on her Macintosh computer that she wants to print.
• The mother has a photo-capable color printer directly attached to her PC, but not shared on the
network.
• The mother and daughter’s computers are not visible to each other on the network.
How can the daughter print her photos on the color printer attached to her mother’s PC? This is
where the USB drive on the router can save you time and effort.
1. The daughter accesses the USB drive by typing \\readyshare in the address field of her Web
browser. Then she copies the photos to the USB drive.
2. The mother uses her Web browser or Microsoft Networking to transfer the files from the USB
drive to the PC. Then she prints the files.
Sharing Large Files with Colleagues
Sending files that are larger than 5 MB can pose a problem for many e-mail systems. The router
allows you to share very large files such as PowerPoint presentations or ZIP files with colleagues
at another site. Rather than filling up their mail systems with large files, your colleagues can use
FTP to easily download shared files from the router.
Sharing files with a remote colleague involves the following considerations:
• There are two user accounts: admin and guest.
• On the FTP site, your colleagues should use the guest user account and enter any password
(FTP requires that you type something in the password field).
Note: The password for admin is the same one that you use to access the router. By
default, it is password. The guest user account has no password.

Cannot Access the Router Main Menu
If you are unable to access the router’s main menu from a computer on your local network, check
the following:
• If you are connecting from a wireless computer, try connecting from a wired computer.
• Check the Ethernet connection between the wired computer and the router. Make sure that the
cable connections are secure, and that you are using the correct cable.
• Make sure that your computer’s IP address is on the same subnet as the router. For
instructions, click the link to the online document “Preparing Your Network” in Appendix B
to configure your computer.
The Internet or Ethernet port lights
are off.
If either the Ethernet port lights or the Internet light does not light when
the Ethernet connection is made, check the following:
• Make sure that the Ethernet cable connections are secure at the
router and at the modem or computer.
• Make sure that power is turned on to the connected modem or
computer.
• Be sure that you are using the correct cable:
When connecting the router’s Internet port to a cable or DSL modem,
use the cable that was supplied with the cable or DSL modem. This
cable could be a standard straight-through Ethernet cable or an
Ethernet crossover cable.

• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try closing the browser and opening it again, or try a different browser.
• Make sure that you are using the correct login information. The factory default login name is
admin, and the password is password. Make sure that Caps Lock is off when entering this
information.
If the router does not save configuration changes that you have made, check the following:
• When entering configuration settings, be sure to click Apply before moving to another screen
or tab, or your changes could be lost.
• Click Refresh or Reload in the Web browser. The changes might have occurred, but the Web
browser might be caching the old configuration.
Cannot Access the Internet
If you can access your router but you are unable to access the Internet, first determine whether the
router can obtain an IP address from your Internet Service Provider (ISP). Unless your ISP
provides a fixed IP address, your router must request an IP address from the ISP. You can
determine whether the request was successful using the Router Status screen.
To check the WAN IP address:
1. Start your browser, and select an external site such as http://www.netgear.com.
2. Access the main menu of the router’s configuration at http://www.routerlogin.net.
3. Under Maintenance, select Router Status.
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has not
obtained an IP address from your ISP.
If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL
modem to recognize your new router by restarting your network, as described in Table 8-1 on
page 8-1.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of the
following:
• Your ISP might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, the login name and password might be set incorrectly.

• Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account as the account name in the Basic Settings
screen.
• Your ISP allows only one Ethernet MAC address to connect to Internet and might check for
your computer’s MAC address. In this case, do one of the following:
– Inform your ISP that you have bought a new network device, and ask them to use the
router’s MAC address.
– Configure your router to spoof your computer’s MAC address.
If your router can obtain an IP address, but your computer is unable to load any Web pages from
the Internet:
• Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically, your ISP provides the addresses of one or two DNS servers
for your use. If you entered a DNS address during the router’s configuration, reboot your
computer, and verify the DNS address as described in the online document you can access
from “Preparing Your Network” in Appendix B. You can also configure your computer
manually with DNS addresses, as explained in your operating system documentation.
• Your computer might not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer, and
verify the gateway address as described in the online document you can access from
“Preparing Your Network” in Appendix B.
• You might be running login software that is no longer needed.
If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer
need to run that software after installing your router. You might need to go to Internet Explorer
and select Tools > Internet Options, click the Connections tab, and select Never dial a
connection.
Troubleshooting a Network Using the Ping Utility
Most network devices and routers contain a ping utility that sends an echo request packet to the
designated device. The device then responds with an echo reply. You can easily troubleshoot a
network by using the ping utility in your computer or workstation.

Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a running Windows PC:
1. From the Windows toolbar, click the Start button, and then select Run.
2. In the field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3. Click OK.
You should see a message like this one:
Pinging <IP address > with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
– For a wired connection, make sure the numbered Ethernet port light is on for the port
to which you are connected. If the light is off, follow the instructions in Table 8-2 on
page 8-3.
– Check that the corresponding Link lights are on for your network interface card. If
your router and computer are connected to a separate Ethernet switch, make sure the
Link lights are on for the switch ports that are connected to your computer and router.
• Wrong network configuration
– Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer.
– Verify that the IP address for your router and your computer are correct and that the
addresses are on the same subnet.

Troubleshooting 8-8
v1.3, October 2009
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote
device.
1. From the Windows toolbar, click the Start button, and then select Run.
2. In the Windows Run window, type:
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies like those shown in the previous section are displayed.
If you do not receive replies:
• Check that your computer has the IP address of your router listed as the default gateway. If the
IP configuration of your computer is assigned by DHCP, this information is not visible in your
computer’s Network Control Panel. Verify that the IP address of the router is listed as the
default gateway as described in the online document you can access from “Preparing Your
Network” in Appendix B.
• Check to see that the network address of your computer (the portion of the IP address specified
by the subnet mask) is different from the network address of the remote device.
• Check that your cable or DSL modem is connected and functioning.
• If your ISP assigned a host name to your computer, enter that host name as the account name
in the Basic Settings screen.
• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a single
computer connected to that modem. If this is the case, you must configure your router to
“clone” or “spoof” the MAC address from the authorized computer.
Problems with Date and Time
Under Content Filtering in the main menu, select E-mail to display a screen that shows the current
date and time of day. The WNDR3700 router uses the Network Time Protocol (NTP) to obtain the
current time from one of several network time servers on the Internet. Each entry in the log is
stamped with the date and time of day. Problems with the date and time function can include the
following:

Wireless Connectivity
The first steps in solving wireless connection problems are these:
1. Using your wireless card’s setup utility program, make sure that your wireless card can find
your wireless router.
2. Configure and test with the simplest wireless connection possible, and then add security.
The topics in this section describe these steps.
Using Your Wireless Card Setup Program
When you install a NETGEAR wireless card in your computer, a Smart Wizard utility program is
installed that can provide helpful information about your wireless network. You can find this
program in your Windows Program menu or as an icon in your system tray. Other wireless card
manufacturers might include a similar program.
If you have no specific wireless card setup program installed, you can use the basic setup utility in
Windows by following these steps:
1. Open the Windows Control Panel, and double-click Network Connections.
2. In the LAN section, double-click Wireless Network Connection.
Use the setup program to scan for available wireless networks. Look for a network name (SSID) of
NETGEAR or your custom SSID if you have changed it. If your wireless network does not appear,
check these conditions:
• Is your router’s wireless radio enabled? See “Restricting Access to Your Router” on page 2-20.
• Is your router’s SSID broadcast enabled? See “Restricting Access to Your Router” on page 2-20.
• Is your router set to a wireless standard that is not supported by your wireless card? Check the
Mode setting, as described in “Manually Configuring Your Wireless Settings” on page 2-4.
