Wireless Performance and Gateway Location
The range of your wireless connection can vary based on the physical placement of the
gateway. The latency, data throughput performance, and notebook power consumption of
wireless adapters also vary depending on your configuration choices.
For best results, place your gateway according to the following guidelines:
•Near the center of the area in which your computers operate.
•In an elevated location such as a high shelf where the wirelessly connected
computers have line-of-sight access (even if through walls).
•Away from sources of interference, such as computers, microwave ovens, and
2.4 GHz cordless phones.
•Away from large metal surfaces.
•To provide the best side-to-side coverage, put the gateway in a vertical position.
•The time it takes to establish a wireless connection can vary depending on both your
security settings and the gateway location. WEP connections can take slightly longer
to establish. Also, WEP encryption can consume more battery power on a notebook
computer.

NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
Set Up Your Wireless Network
To set up the wireless network, you can enter wireless settings, (see Configure Wireless
Settings Manually on page 13), or you can use Wi-Fi Protected Setup (WPS), (see Use Push
'N' Connect (WPS) Wireless Setup on page 16). To wirelessly connect to the gateway, a
computer or wireless device must be configured with the same wireless settings as the
gateway.
•The default wireless network name (SSID) for the gateway is the last six digits of the WiFi
MAC address. NETGEAR recommends that you change this name for better wireless
security and to make it easier to recognize your network when you want to connect to it
wirelessly.
•By default the gateway works with WPA and WPA 2 wireless security. The default
password is the 13-character device serial number.
•To use Push 'N' Connect (WPS), your wireless computers and equipment must support
WPS technology. See Use Push 'N' Connect (WPS) Wireless Setup on page 16.
Configure Wireless Settings Manually
You can manually configure the wireless settings and security for both the 2.4 GHz and
5
GHz networks in the Wireless Settings screen.
To view or configure the wireless settings:
1. If you are located near the gateway, use an Ethernet cable to connect your computer to
the gateway while you are changing the wireless settings.
Note: If you connect wirelessly to the gateway and then change its
wireless network name (SSID) or wireless security, you will be
disconnected after you click Apply.
2. Log in to the gateway.
For more information, see Log In to Your Gateway on page 10.
3. In the main menu, under Setup, select Wireless Settings.

NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
4. Specify the Wireless Network settings for each network:
•Name (SSID). The name of the wireless network.
•Region. The location where the gateway operates.
•Channel. The available channels depend on the region. Some countries have laws
specifying which channels should be used. To reduce interference when using more
than one access point, NETGEAR recommends using 5-channel spacing between
adjacent access points (for example, use Channels 1 and 6, or 6 and 11).
•802.11 Mode. This value is set to Up to 145 Mbps by default. You can specify the
mode to support faster equipment or legacy equipment.
5. Specify the security options for either the 2.4 GHz or the 5 GHz network or both.
By default the gateway is set up to work with both WPA and WPA2 wireless security. (This
security option is already selected.) You can specify the network key, which works like a
password to access the wireless network.
a. Set up WPA or WPA2 wireless security:
•WPA-PSK. This setting provides the TKIP encryption type and a pre-shared key
password.
•WPA2-PSK. This setting provides the AES encryption type and a pre-shared key
password.
Note: Configure your wireless computers with the same WPA2 or WPA
settings as your gateway so that you can connect.
b. Depending on the WPA settings that you select, enter the required information.
For WPA-PSK or WPA2-PSK, enter the pre-shared key, which is a password between
8
and 63 characters. The default WPA password is the 13-character serial number of
your gateway.
Note: By default, the gateway is set up to work with WPA and WPA2
wireless security, both of which are newer than WEP. Typically, the
only reason you might need to set up WEP would be to allow access
to older wireless computers or devices that cannot support WPA.
6. Click Apply.
Wireless Configuration
16
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
Note: If you plan to use WPS, and you want to keep your wireless settings

sure that the Keep Existing Settings check box is selected. See
Advanced Wireless Settings (2.4 GHz and 5 GHz)on page 30.
Use Push 'N' Connect (WPS) Wireless Setup
Push 'N' Connect (WPS) can be a quick way to automatically set up your gateway’s wireless
network and set up your wireless computer to connect to it at the same time. WPS, also
called Wi-Fi Protected Setup, is relatively new technology, so before you decide to use it,
check to make sure your wireless computers and devices support WPS. Look for the
symbol on all the computers that connect wirelessly to the gateway.
If you do not see the symbol on all the computers that connect to the wireless network,
then you should manually set up your network first (see Configure Wireless Settings
Manually on page 13). After that, you can still use WPS to set up the wireless connection for
the computers that support WPS.
Note: All WPS-capable products should be compatible with the gateway.
For more information about the WPS standard, visit
http://www.wi-fi.org).
Two Push 'N' Connect methods are available, WPS button and PIN (personal identification
number).
Add a Client Using the WPS Button
Note: The first time you use WPS, it assigns a random network name
(SSID) and a random password to your wireless network. If you want
to keep the network name and password you specified in the
Wireless Settings screen, you must select the Keep Existing
Settings check box in the Advanced Wireless Settings screen. See
Advanced Wireless Settings (2.4 GHz and 5 GHz) on page 30.
Any computer or wireless device that connects wirelessly to the gateway is a client. After a
device is added as a client, it can automatically connect to the gateway.

Add Custom Service table, click Reset.
Port Forwarding
A firewall has default rules for inbound traffic (WAN to LAN) and for outbound traffic. Port
forwarding affects the inbound rules. These rules restrict access from outsiders. By default,
the gateway blocks access from outside except for responses to requests from the LAN side.
You can use port forwarding to add rules to specify exceptions to the default rule.
Because the gateway uses Network Address Translation (NAT), your network presents only
one IP address to the Internet, and outside users cannot directly address 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) or computer visible and available to the Internet. The rule tells
the gateway to direct inbound traffic for a particular service to one local server or computer
based on the destination port number. Directing traffic is also known as port forwarding.
Some residential broadband ISPs do not allow you to run server processes (such as a web or
FTP server) from your location. Your ISP might check for servers and suspend your account
if it finds active services at your location. See the ISP’s Acceptable Use policy.
Pay attention to the following considerations before configuring port forwarding:
•If the DHCP assigns the IP address of the local server computer, the address might
change when the computer is rebooted. To keep the address from changing, you can
assign a static IP address to your server outside the range that DHCP assigns, but in the
same subnet as your LAN. By default, the IP addresses from 192.168.0.2 through
192.168.0.9 are reserved for this purpose.
•Local computers must access the local server using the computers’ local LAN address
(192.168.0.XXX, by default). Attempts by local computers to access the server using the
external WAN IP address fail.
•Port forwarding opens holes in your firewall. Enable only ports that are necessary.
To configure port forwarding and services for specific inbound traffic:
1. In the main menu, under Advanced, select Port Forwarding.
Advanced Settings
35
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
2. From the Service list, select the service for
which you want to configure port forwarding.
3. To add a custom rule that is not in the list of
services, specify these settings in the Add
Custom Service table:
•Name. A name for the service.
•Start Port. The start port for the service.
•End Port. The end port for the service.
•Protocol. The protocol for the ports:
- TCP. TCP only.
- UDP. UDP only.
- Both. Both TCP and UDP.
•Local IP Address. Complete the local IP
address for the computer that is using the
service.
4. Perform one of these actions:
•Click Add. The Active Forwarding Rules table displays the list of forwarded ports.
•To delete a service, select the radio button in the Active Forwarding Rules table for
the service that you want to delete, and click Delete.
•To reset the selection in the Service list and to clear all the fields in the Add Custom
Rules, click Reset.
Port Triggering
Port triggering is an advanced feature that you can use to allow gaming and other Internet
applications that the firewall would otherwise block. You must know the port numbers the
application uses. Port triggering operates as follows:
1. A computer makes an outgoing connection using a port number defined in the Port
Triggering table.
2. The gateway records this connection, opens the incoming port or ports associated with this
entry in the Port Triggering List, and associates them with the computer.
3. The remote system receives the computer’s request, and responds using a different port
number.
4. The gateway matches the response to the previous request, and forwards the response to
the computer. (Without port triggering, this response would be treated as a new connection
request rather than a response. As such, it would be handled in accordance with the port
forwarding rules.)
Advanced Settings
36
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
Note: Only one computer at a time can use port triggering. After a
computer finishes using a port triggering application, there is a short
time-out period before another computer can use the application.
To configure port triggering:
1. In the main menu, under Advanced, select Port Triggering.
2. For each port trigger, enter the settings in the Port
Triggering List:
•Trigger Range. To specify the range of
outgoing ports that are monitored to trigger
the incoming port forwarding rule, enter the
start port and end port.
•Target Range. To specify the range of
incoming ports that are opened when
triggered, enter the start port and end port.
•Protocol. Select the protocol for the ports:
- TCP. Select TCP only.
- UDP. Select UDP only.
- Both. Select both TCP and UDP.
3. Select the Enable check box for the port trigger.
4. Perform one of the following actions:
•Click Apply to save your settings and
activate the port triggers.
•To remove a port trigger, select its radio button, and click Delete.
•To return all trigger and target ranges to zero, click Reset.
DMZ Host
You can use the DMZ Host screen to set up a default DMZ computer. Specifying a default
DMZ computer allows you to set up a computer that is available to anyone on the Internet for
services that you have not defined. To minimize security risks, set up the DMZ host only if
you are willing to risk open access. If you do not define a DMZ host, the gateway discards
any undefined service requests.
Advanced Settings
37
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
To set up a DMZ host:
1. In the main menu, under Advanced, select DMZ Host.
2. Select the Respond to Ping on WAN Port check box.
When you select this check box, the gateway responds to a ping request instead of the
DMZ computer.
For example, some systems tracking the performance of the broadband connections in
terms of latency and packet loss need the gateway to reply to ping requests.
3. Type the last digits of the IP address in the DMZ Address field.
The DMZ host feature is disabled when the last digit is zero.
4. Click Apply.
LAN IP Setup
The LAN IP screen allows you to configure LAN services such as the IP address of the
gateway and DHCP. The TCP/IP and DHCP default values work fine in most cases.
Note: If you disable the DHCP server, assign to your computer a static IP
address to reconnect to the gateway and enable the DHCP server
again.

Remote Management
With remote management, you can allow a user or users on the Internet to configure,
upgrade, and check the status of the gateway.
Note: Use secure passwords if you enable remote management.
Passwords should contain no dictionary words from any language,
and should be a mixture of letters (both uppercase and lowercase),
numbers, and symbols. Your password can be up to 16 characters.
To manage this gateway through the Internet, you need its public IP address, as seen from
the Internet. Your ISP allocates this public IP address. But if your ISP account uses a
dynamic IP address, the address can change each time you connect to your ISP. This
problem has two solutions:
•Have your ISP allocate you a fixed IP address.
•Use the DDNS (Dynamic DNS) feature so you can connect using a domain name, rather
than an IP address.
To configure the gateway for remote management:
1. In the main menu, under Advanced, select Remote Management.

4. Enter a password in the Remote Password field.
To access the gateway, use this password from the remote computer.
5. To access the gateway remotely in your browser when you connect, specify the port
number. To determine the port number:
a. From a remote location, start a browser.
b. In the Address or Location field, enter the Internet IP address of this gateway (not
the LAN IP address), followed by a colon and the port number, as follows:
http://ip_address:pn || https://ip_address:pn
where:
ip_address is the Internet IP address of this gateway.
pn is the port number assigned on this screen.
6. Enter the password for the gateway.
7. Specify the permitted IP addresses for remote management.
a. To allow remote management from any originating IP address, select the ALL IP
Addresses check box.
NETGEAR strongly recommends not using this option unless it is required.
b. From the Address Type list, select either Single Address or Address Range.
c. Enter the permitted IP addresses.
You can enter a single IP address or up to 16 IP addresses ranges. Each range
begins with a start IP address and finishes with an end IP address in the format of
start IP - end IP.
8. Click Apply.
Configure Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
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. With
UPnP, you can specify the following:
•Advertisement period. Specifies how often the gateway broadcasts its UPnP
information. The default is 30 minutes. Lower numbers ensure that control points
have current device status at the expense of more network traffic. Larger numbers
compromise the freshness of the device status but can significantly reduce network
traffic.
Advanced Settings
41
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
•Advertisement time to live. The time to live for the advertisement, measured in hops
(steps) for each UPnP packet that is sent. Hops are the steps a packet takes between
routers. The number of hops can range from 1 to 255. The default value for the
advertisement time to live is four hops, which should be fine for most home networks.
If you notice that some devices are not being updated or reached correctly, you might
need to increase this value slightly.
To configure UPnP:
1. In the main menu, under Advanced, select UPnP.
2. Select the Turn UPnP On check box.
By default, this check box is cleared. This
prevents the gateway from allowing any
device to automatically control the
resources, such as port forwarding, of
the gateway.
3. Complete the Advertisement Period and
Advertisement Time to Live fields.
The UPnP Portmap Table displays the IP
address of each UPnP device that is
accessing the gateway and which
internal and external ports of the
gateway that device opened. The UPnP Portmap Table also displays the protocol for the
port that was opened and if that port is still active for each IP address.
4. Perform one of the following actions:
•Click Apply to save your settings.
•Click Cancel to disregard any unsaved changes.
•Click Refresh to update the UPnP Portmap Table and to show the active ports that

Basic Functions
After you have turned on power to the gateway, do the following:
1. Check to see that the Power LED is lit.
2. Check that the numbered Ethernet LEDs light momentarily.
3. After a few seconds, check that the LEDs are lit for any local ports that are connected.
The following table provides help when you are using the LEDs for troubleshooting.
All LEDs are off when the gateway
is plugged in.
• Make sure that the power cord is properly connected to your
gateway and that the power supply adapter is properly connected
to a functioning power outlet.
• Check that you are using the 12V-DC power adapter supplied by
NETGEAR for this product.
If the error persists, you have a hardware problem and should contact
technical support.
All LEDs stay on. Clear the gateway’s configuration to factory defaults to set the
gateway’s IP address to 192.168.0.1. See Factory Default Settings on
page 49.
If the error persists, you might have a hardware problem and should
contact technical support.
LAN LED is off for a port with an
Ethernet connection.
• Make sure that the Ethernet cable connections are secure at the
gateway and at the hub or computer.
• Make sure that power is turned on to the connected hub or
computer.
• Be sure that you are using the correct cable.
Internet LED is off and the
gateway is connected to the cable
television cable.
• Make sure that the coaxial cable connections are secure at the
gateway and at the wall jack.
• Make sure that your cable service provider has provisioned your
Internet service. Your provider should verify that the signal quality
is good enough for cable modem service.
• Remove any excessive splitters you might have on your cable line.
It might be necessary to run a “home run” back to the point where
the cable enters your home.
Connect to the Gateway’s Main Menu
If you are unable to access the gateway’s main menu from a computer on your local network,
check the following:
•Check the Ethernet connection between the computer and the gateway as described in
the previous section.
LED Behavior Action
Troubleshooting
45
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
•Make sure that your computer’s IP address is on the same subnet as the gateway. If you
are using the recommended addressing scheme, your computer’s address should be in
the range of 192.168.0.10 to 192.168.0.254.
Note: If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS 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 gateway and reboot your computer.
•If your gateway’s IP address has been changed and you do not know the current IP
address, clear the gateway’s configuration to factory defaults. This action sets the
gateway’s IP address to 192.168.0.1. For more information, see Factory Default Settings
on page 49.
•Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to make sure that the Java applet is loaded.
•Try quitting the browser and launching it again.
•Make sure that you are using the correct login information. The gateway user name
admin is lowercase (Caps Lock should be off). The default password is password.
If the gateway does not save changes you have made, check the following:
•When entering configuration settings, be sure to click the Apply button before moving to
another screen, or your changes are lost.
•Click the Refresh or Reload button in the web browser. The changes might have
occurred, but the web browser might be caching the old configuration.
Troubleshoot the ISP Connection
If your gateway is unable to access the Internet and your Internet LED is on, you might need
to register the cable MAC address or device MAC address of your gateway with your cable
service provider.
Additionally, your computer might not have the gateway configured as its TCP/IP gateway. If
your computer obtains its information from the gateway by DHCP, reboot the computer and
verify the gateway address. For more information, see Reserve an IP Address for DHCP Use
on page 38.
Troubleshoot a TCP/IP Network Using a 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. You can
Troubleshooting
46
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
easily troubleshoot a TCP/IP network by using the ping utility in your computer or
workstation.
Test the LAN Path to Your Gateway
You can use ping to verify that the LAN path to your gateway is set up correctly.
To ping the gateway from a computer 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 gateway, as in this
example:
ping 192.168.0.1
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 working correctly, you could have one of the following problems:
•Wrong physical connections.
- Make sure that the LAN port LED is lit. If the LED is off, see Basic Functions on
page 44.
- Check that the corresponding LEDs are on for your network interface card and for
the hub ports (if any) that are connected to your workstation and gateway.
•Wrong network configuration.
- Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your computer or workstation.
- Verify that the IP address for your gateway and your workstation are correct and
that the addresses are on the same subnet.
Test 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. From the Windows run menu, type:
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.
Troubleshooting
47
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
If the path is functioning correctly, replies as in the previous section are displayed. If, you do
not receive replies:
•Check that your computer has the IP address of your gateway listed as the default
gateway. If DHCP assigns the IP configuration of your computer, this information is not
visible in your computer’s Network Control Panel. Verify that the IP address of the
gateway is listed as the default gateway.
•Check to see that the network address of your computer (the portion of the IP address
specified by the netmask) is different from the network address of the remote device.
•Check that your Internet LED is on.
