To configure the wireless network, you can either specify the wireless settings, or you can use WiFi 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 router is NETGEAR-3G.
–
The wireless mode (80.211n, 802.11g, or 802.11b) 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.

•
Push 'N' Connect (WPS) automatically implements wireless security on the 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 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 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 2-9.
Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the 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 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-ofsight 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.
•
Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
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 Wireless 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:
Figure 2-1
•
Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the router. Restricting access by MAC address
adds an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
•
Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies wireless network
‘discovery’ feature of some products, such as Windows XP, but the data is still exposed.
•
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-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication
implemented using IEE 802.1x and RADIUS servers.
•
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 router’s SSID and security settings and, at the same time, connect the wireless client securely
and easily to the router. Look for the
symbol on your client device (computers that will
connect wirelessly to the router are clients). WPS automatically configures the network name
(SSID) and wireless security settings for the router (if the router is in its default state) and
broadcasts these settings to the wireless client.
Some considerations regarding WPS are:
•
WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not
supported by WPS.
•
NETGEAR’s Push 'N' Connect feature is based on the WPS standard. All other Wi-Fi-certified
and WPS-capable products should be compatible with NETGEAR products that implement
Push 'N' Connect.
•
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 2-13.
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”.
•
Entering a PIN. For information about using the PIN method, see “Using PIN Entry to Add a
WPS Client” on page 2-11.
Using a WPS Button to Add a WPS Client
Any wireless computer or wireless adapter that will connect to the 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 router WPS button to add a WPS client:
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin and default password of password, or using whatever LAN address and password
you have set up.

Note: If no WPS-capable client devices are located during the 2-minute timeframe, the
SSID will not be changed, and no security will be implemented on the router.
Using PIN Entry to Add a WPS Client
Any wireless computer or wireless adapter that will connect to the 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 router, and allows it to
generate the SSID and WPA/WPA2 security settings when it implements WPS. After WPS is
implemented, the 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.
To use a PIN to add a WPS client:
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin and default password of password, or using whatever LAN address and password
you have set up.

Chapter 3
Protecting Your Network
This chapter describes how to use the basic firewall features of the Wireless Router to protect your
network.
Protecting Access to Your Wireless Router
For security reasons, the 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 adminCfor the router user name and password for the router password. You can
use procedures in the following sections to change the router password and the amount of time for
the administrator’s login time-out.
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.
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.
Changing the Built-In Password
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin, default password of password, or using whatever password and LAN address you
have chosen for the router.

3. To change the password, first enter the old password, and then enter the new password twice.
4. Click Apply to save your changes.
Note: After changing the password, you must log in again to continue the
configuration. If you have backed up the router settings previously, you should
do a new backup so that the saved settings file includes the new password.
Changing the Administrator Login Time-out
For security, the administrator login to the router configuration times out after a period of
inactivity. To change the login time-out period:
1. In the Set Password screen, type a number in the Administrator login times out field. The
suggested default value is 5 minutes.
2. Click Apply to save your changes, or click Cancel to keep the current period.

Blocking Keywords, Sites, and Services
The router provides a variety of options for blocking Internet-based content and communications
services. With its content filtering feature, the router prevents objectionable content from reaching
your PCs. You can control access to Internet content by screening for keywords within Web
addresses. Content filtering options include:
•
Keyword blocking of HTTP traffic.
•
Outbound service blocking. Limits access from your LAN to Internet locations or services that
you specify as off-limits.
•
Denial of service (DoS) protection. Detects and thwarts denial of service (DoS) attacks such as
Ping of Death, SYN flood, LAND attack, and IP spoofing.
•
Blocking unwanted traffic from the Internet to your LAN.
The following section explains how to configure your router to perform these functions.
Blocking Keywords and Sites
The router allows you to restrict access to Internet content based on Web addresses and Web
address keywords.
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin, and default password of password, or using whatever password and LAN address
you have chosen for the router.

Firewall Rules
Firewall rules block or allow specific traffic passing through from one side of the router to the
other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively
allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN)
determine what outside resources local users can have access to.
The default inbound and outbound rules of the router are:
• Inbound. Block all access from outside except responses to requests from the LAN side.
• Outbound. Allow all access from the LAN side to the outside.
You can define additional rules that will specify exceptions to the default rules. By adding custom
rules, you can block or allow access based on the service or application, source or destination IP
addresses, and time of day. You can also choose to log traffic that matches or does not match the
rule you have defined.
You can change the order of precedence of rules so that the rule that applies most often will take
effect first. See “Order of Precedence for Rules” for more details.
To view or change firewall rules, select Firewall Rules on the main menu.

Inbound Rules (Port Forwarding)
Because the router uses Network Address Translation (NAT), your network presents only one IP
address to the Internet, and outside users cannot directly access any of your local computers.
However, by defining an inbound rule you can make a local server (for example, a Web server or
game server) visible and available to the Internet. The rule tells the router to direct inbound traffic
for a particular service to one local server based on the destination port number. This is also known
as port forwarding.
Note: Some broadband ISP accounts do not allow you to run any server processes (such
as a Web or FTP server) from your location. Your ISP might periodically check for
servers and might suspend your account if it discovers any active services at your
location. If you are unsure, see the acceptable use policy of your ISP.
Remember that allowing inbound services opens holes in your firewall. Enable only those ports
that are necessary for your network. Following are two application examples of inbound rules.
Inbound Rule Example: A Local Public Web Server
If you host a public Web server on your local network, you can define a rule to allow inbound Web
(HTTP) requests from outside IP addresses to the IP address of your Web server at any time of day.
This rule is shown in the following figure:

You can create an inbound rule to allow incoming videoconferencing to be initiated from a
restricted range of outside IP addresses, such as from a branch office. In this example, CU-SeeMe
connections are allowed only from a specified range of external IP addresses. This example also
specifies logging of any incoming CU-SeeMe requests that do not match the allowed parameters.

Considerations for Inbound Rules
If your external IP address is assigned dynamically by your ISP, the IP address might change
periodically as the DHCP lease expires. Consider using the Dynamic DNS feature so that external
users can always find your network.
If the IP address of the local server computer is assigned by DHCP, it might change when the
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to
keep the computer’s IP address constant.
Local computers must access the local server using the computer’s local LAN address
(192.168.0.11 in the previous example). Attempts by local computers to access the server using the
external WAN IP address will fail.
Outbound Rules (Service Blocking)
The router allows you to block the use of certain Internet services by computers on your network.
This is called service blocking or port filtering. You can define an outbound rule to block Internet
access from a local computer based on the following:
• IP address of the local computer (source address)
• IP address of the Internet site being contacted (destination address)
• Time of day
• Type of service being requested (service port number)
Outbound Rule Example: Blocking Instant Messenger
If you want to block Instant Messenger usage by employees during working hours, you can create
an outbound rule to block that application from any internal IP address to any external address
according to the schedule that you have created in the Schedule screen. You can also have the
router log any attempt to use Instant Messenger during that blocked period.

Order of Precedence for Rules
As you define new rules, they are added to the tables in the Firewall Rules screen, as shown:
Figure 3-7
For any traffic attempting to pass through the firewall, the packet information is subjected to the
rules in the order shown in the rules table, beginning at the top and proceeding to the default rules
at the bottom. In some cases, the order of precedence of two or more rules might be important in
determining the disposition of a packet. The Move button allows you to relocate a defined rule to a
new position in the table.
Services
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 the Internet sends a request for
service to a server computer, 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.
The service numbers for many common protocols are defined by the Internet Engineering Task
Force (IETF) and published in RFC 1700, “Assigned Numbers.” Service numbers for other
applications are typically chosen from the range 1024 to 65535 by the authors of the application.
Although the router already holds a list of many service port numbers, you are not limited to these
choices. Use the following procedure to define your own services.

Selected by default, the router broadcasts its SSID, allowing
wireless stations that have a null (blank) SSID to adopt the
correct SSID. If you disable broadcast of the SSID, only
devices with the correct SSID can connect. This nullifies the
wireless network discovery feature of products such as
Windows XP, but the data is still exposed to equipment like
wireless sniffers. For this reason NETGEAR recommends that
you also enable wireless security.

Wireless Station Access Control
By default, any wireless PC that is configured with the correct SSID and wireless security settings
is allowed access to your wireless network. You can use Wireless Access Point settings in the
Wireless Setting screen to further restrict wireless access to your network:
•
Turning off wireless connectivity completely.
You can completely turn off the wireless portion of the router. For example, if you use your
notebook computer to wirelessly connect to your router, and you take a business trip, you can
turn off the wireless portion of the router while you are traveling. Other members of your
household who use computers connected to the router via Ethernet cables can still use the
router. To do this, clear the Enable Wireless Access Point check box on the Wireless Settings
screen, and then click Apply.
•
Hiding your wireless network name (SSID).
By default, the router is set to broadcast its wireless network name (SSID). You can restrict
wireless access to your network by not broadcasting the wireless network name (SSID). To do
this, clear the Allow Broadcast of Name (SSID) check box on the Wireless Settings screen,
and then click Apply. Wireless devices will not “see” your router. You must configure your
wireless devices to match the wireless network name (SSID) of the router.
Note: The SSID of any wireless access adapters must match the SSID you configure
in the router. If they do not match, you will not get a wireless connection to the
router.

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 Wireless 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 router at its default LAN address of http://192.168.0.1 with its default user name
of admin, and default password of password, or using whatever user name, password, and
LAN address you have chosen for the router.
Note: If you configure the Product Family 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 router
from a wired computer, or from a wireless computer that is on the access
control list, to make any further changes.
2. From the main menu, select Wireless Settings, and then click Setup Access List to display the
Wireless Station Access List screen.

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.
Setting Up a Default DMZ Server
Warning: For security reasons, you should avoid using the default DMZ server feature.
When a computer is designated as the default DMZ server, it loses much of
the protection of the firewall, and is exposed to many exploits from the
Internet. If compromised, the computer can be used to attack your network.
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with NAT. The router is programmed to
recognize some of these applications and to work properly with them, but there are other
applications that may not function well. In some cases, one local computer can run the application
properly if that computer’s IP address is entered as the default DMZ server.
Incoming traffic from the Internet is normally 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 Ports 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.
To assign a computer or server to be a default DMZ server:

The router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a
DHCP server. The router default LAN IP configuration is:
• LAN IP addresses: 192.168.0.1
• Subnet mask: 255.255.255.0
These addresses are part of the Internet Engineering Task Force (IETF)-designated private address
range for use in private networks, and should be suitable in most applications. If your network has
a requirement to use a different IP addressing scheme, you can make those changes in this screen.

RIP Direction
RIP (Router Information Protocol) allows a router to
exchange routing information with other routers. This
setting controls how the router sends and receives RIP
packets. Both is the default.
• Both or Out Only. The router broadcasts its routing table
periodically.
• Both or In Only. The router incorporates the RIP
information that it receives.
• None. The router will not send any RIP packets and will
ignore any RIP packets received.
RIP Version
This controls the format and the broadcasting method of the
RIP packets that the router sends. It recognizes both
formats when receiving. By default, this is RIP-1.
• 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.

DHCP Settings
By default, the router functions as a Dynamic Host Configuration Protocol (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. IP
addresses is assigned to the attached PCs 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. See the
online document listed in “Internet Networking and TCP/IP Addressing” in Appendix B for an
explanation of DHCP and information about how to assign IP addresses for your network.
Use Router as DHCP Server
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the Use Router as DHCP Server check box on
the LAN IP Setup screen. Otherwise, leave it selected.
Specify the pool of IP addresses to be assigned by filling in the Starting IP Address and Ending
IP Address fields. 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
192.168.0.2 and 192.168.0.254, although you might want 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 is 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.
•
WINS Server (Windows Internet Naming Service Server), determines the IP address
associated with a particular Windows computer. A WINS server records and reports a list of
names and IP address of Windows PCs on its local network. If you connect to a remote
network that contains a WINS server, enter the server’s IP address here. This allows your PCs
to browse the network using the Network Neighborhood feature of Windows.

Reserved IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it access the router’s DHCP server. Reserved IP addresses
should be assigned to servers that require permanent IP settings.
To reserve an IP address:
1. Click the Add button.
2. In the IP Address field, type the IP address to assign to the computer or server. Choose an IP
address from the router’s LAN subnet, such as 192.168.0.x.
3. Type the MAC address of the computer or server.
Tip: If the computer is on your network, it is listed on the same page for your
convenience. Clicking the radio button for each entry in the attached device list
fills in the fields automatically with the computer’s MAC address and name.
4. Click Apply to enter the reserved address into the table.
Note: The reserved address will not be 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.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.
Dynamic DNS
If your network has 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 will 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 to register your domain to their IP address, and forward traffic directed at
your domain to your frequently changing IP address.
The router contains a client that can connect to a Dynamic DNS service provider. To use this
feature, you must select a service provider and obtain an account with them. After you have

Using Static Routes
Static routes provide additional routing information to your router. Under normal 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.
Static Route Example
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 192.168.0.100.
•
Your company’s network 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 router, and a second static route was created to your local network for
all 192.168.0.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 192.168.0.100. The static route would look like Figure 5-7.
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 fields specify that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.

Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access

default setting for UPnP is enabled. If disabled, the router will 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 advertises
(broadcasts) its UPnP information. This value can range from 1 to 1440 minutes. The
default period is for 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.

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 a little.

Wireless Bridging and Repeating
You can build large bridged wireless networks by using the router to configure a wireless
distribution system (WDS). Some examples of wireless bridged configurations are:
•
Point-to-Point bridge. The router communicates with another bridge-mode wireless station.
See “Point-to-Point Bridge Configuration”.
•
Multi-Point bridge. The router is the “master” for a group of bridge-mode wireless stations.
Then all traffic is sent to this “master,” rather than to other access points. See “Multi-Point
Bridge Configuration”.
•
Repeater with wireless client association. Sends all traffic to the remote access point. See
“Repeater with Wireless Client Association”.

Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power
LED is on.
2. After approximately 10 seconds, verify that:
a. The Power LED is still solid green. A red light indicates the unit has failed its power-on
self-test (POST).
b. The Ethernet LAN port LEDs are lit for any local ports that are connected.
If a LAN port’s LED is lit, a link has been established to the connected device. If a LAN
port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is
10 Mbps, the LED is amber.
c. The USB and Internet LEDs are lit.

•
Make sure your computer’s IP address is on the same subnet as the router. If you are using the
recommended addressing scheme, your computer’s address should be in the range of
192.168.0.2 to 192.168.0.254. See the online document listed in “Preparing a Computer for
Network Access” in Appendix B to find your computer’s IP address.
Note: If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS generate and assign an IP address if
the computer cannot reach a DHCP server. These auto-generated addresses are
in the range of 169.254.x.x. If your IP address is in this range, check the
connection from the computer to the router, and reboot your computer.
•
If your router’s IP address was changed and you do not know the current IP address, clear the
router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1.
This procedure is explained in “Restoring the Default Configuration and Password” on
page 6-7.
•
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 quitting the browser and launching it again.
•
Make sure 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 changes you have made in the Web configuration interface, check the
following:
•
When entering configuration settings, be sure to click the Apply button before moving to
another screen or tab, or your changes are lost.

Troubleshooting the ISP Connection
Obtaining a WAN IP Address
If your router is unable to access the Internet, and your Internet LED is green or blinking green,
determine whether the router is able to obtain a WAN IP address from the ISP. Unless you have
been assigned a static IP address, your router must request an IP address from the ISP. You can
determine whether the request was successful using the browser interface.
To check the WAN IP address:
1. Launch your browser, and select an external site such as www.netgear.com.
2. Access the router main menu at http://192.168.0.1.
3. Under the Maintenance heading, check that an IP address is shown for the WAN port.
If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, the problem might be one of the
following:
•
Your ISP might require a multiplexing method or virtual path identifier or virtual channel
identifier parameter.
Verify with your ISP the multiplexing method and parameter value, and update the router’s
ADSL settings accordingly.
•
Your ISP might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or PPP over ATM (PPPOA)
login.
•
If you have selected a login program, the service name, user name, and password might be set
incorrectly. See “Troubleshooting PPPoE or PPPoA”, below.
•
Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account to the router in the browser-based Setup
Wizard.
•
Your ISP only allows one Ethernet MAC address to connect to Internet, and might check for
your computer’s MAC address. In this case try either 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. This can be done in the
Basic Settings screen.

Troubleshooting
v1.0, October 2009
Mobile Broadband Wireless-N Router MBRN3000 User Manual
Troubleshooting PPPoE or PPPoA
The PPPoA or PPPoA connection can be debugged as follows:
1. Access the main menu of the router at http://192.168.0.1.
2. Under the Maintenance heading, select Router Status.
3. Click Connection Status.
4. If all of the steps indicate OK, then your PPPoE or PPPoA connection is up and working.
5. If any of the steps indicates Failed, you can attempt to reconnect by clicking Connect. The
router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, the service name, user name, or password might be
incorrect. There also might be a provisioning problem with your ISP.
Note: Unless you connect manually, the router will not authenticate using PPPoE or
PPPoA until data is transmitted to the network.
Troubleshooting Internet Browsing
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 “Preparing a Computer for Network
Access” in Appendix B. Alternatively, you can 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 router.
If your computer obtains its information from the router by DHCP, reboot the computer, and
verify the router address as described in the link to the online document “Preparing a
Computer for Network Access” in Appendix B.

Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal 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. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in your computer.
Testing the LAN Path to Your Router
You can ping the router from your PC to verify that the LAN path to your router is set up correctly.
To ping the router from a PC running Windows 95 or later:
1. From the Windows toolbar, click the Start button, and select Run.
2. In the field provided, type ping followed by the IP address of the router, as in this example:
ping 192.168.0.1
3. Click OK.
You should see a message like this one:
Pinging  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 working correctly, you could have one of the following problems:
• Wrong physical connections
–
Make sure that the LAN port LED is on. If the LED is off, follow the instructions in
Table 6-1 on page 6-2.
–
•
Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
Wrong network configuration
–
Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your PC or workstation.
–
Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.

Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to a remote device.
1. From the Windows toolbar, click the Start button, and 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 as in the previous section are displayed. If you do not
receive replies:
•
Check that your PC has the IP address of your router listed as the default router. If the IP
configuration of your PC is assigned by DHCP, this information is not visible in your PC’s
Network Control Panel. Verify that the IP address of the router is listed as the default router as
described in the online document listed in “Preparing a Computer for Network Access” in
Appendix B.
•
Make sure that the network address of your PC (the portion of the IP address specified by the
netmask) 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 PC, 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 PCs. Many
broadband ISPs restrict access by allowing only traffic from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a single
PC connected to that modem. If this is the case, you must configure your router to clone or
spoof the MAC address from the authorized PC. See the Mobile Broadband Wireless-N Router
MBRN3000 Installation Guide.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to password and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
• Use the Erase function (see “Backing Up, Restoring, or Erasing Your Settings” on page 4-1).

•
Press both the Wireless button and WPS button on the side of the router for 5 seconds. Use this
method for cases when the administration password or IP address is not known.
Note: Pressing the reset button on the router reboots the unit but does not restore the
factory default settings.
Problems with Date and Time
The E-mail screen in the Content Filtering section displays the current date and time of day. The
Wireless 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:
•
Date shown is January 1, 2000.
Cause: The router has not yet successfully reached a network time server. Check that your
Internet access settings are configured correctly. If you have just completed configuring the
router, wait at least 5 minutes, and check the date and time again.
•
Time is off by one hour.
Cause: The router does not automatically sense daylight savings time. On the E-mail screen,
select or clear the Adjust for Daylight Savings Time check box.
