You will see a series of prompts warning you that the firmware is about to be updated. Please do not disconnect the power from the router at this time as it could cause the system to fail.

Updating the Router’s Firmware via the Web Interface
The following steps show you how to update your router’s firmware using its web interface. You do not need to be connected to the Internet as this interface is built into the router itself.

Setup steps:

Locate and download the firmware file from the Belkin support site. (Type your part number into the search box in the top right corner and look for “Firmware” in the title.)
Save the file to a location on your computer where you can get to it easily, such as your desktop.
Connect the computer to one of the four LAN ports on the router (refer to image).
Open a web browser on the computer.
In the address bar of the web browser, type “http://router” or “http://192.168.2.1” and press Enter on your keyboard.
Click on Firmware Update toward the bottom right corner.
Click Choose File toward the middle of the screen to search for the file you saved previously.
Select the firmware file by left-clicking on it and then click Open in the lower-right corner of the window. This will take you back into the router’s interface.
Note—The firmware version in the image above is depicted as an example. Your file name will vary depending on your model and version.

Troubleshooting Guide

My device can’t connect to the Internet wirelessly.

If the router status light is solid blue, your router is connected to the Internet. Your device might not be connected to the router’s wireless network. Please refer to "Connect Your Wireless Devices" on page 18 for instructions.
If your Windows XP computer is running SP2, you will not be able to set up the router via the wireless setup process. You will need to update to Windows XP SP3 or complete the setup via a wired connection.

I can’t connect to the Internet wirelessly and my network name is not listed in Available Networks.

Verify that your router is on and the router status light is solid blue.
If you are far from the router, try moving closer to see if you are out of range.
Using a computer attached to the router via a network cable, visit http://router/ and ensure that Broadcast SSID is ON. This setting is found on the Channel and SSID page.

My wireless network performance is slow, inconsistent, suffers from weak signal, or I’m having difficulty maintaining a VPN connection.
Wireless technology is radio-based. Connectivity, speed, and throughput between devices decrease as distance between devices increases. Other factors that will cause signal degradation are obstructions such as walls and metal appliances. To determine if wireless issues are related to range, we suggest temporarily moving a connected device to within 10 feet from the router, if possible.Some things you can do to improve your router’s performance:

Changing the wireless channel: Depending on local wireless traffic and interference, switching the wireless channel of your network can improve performance and reliability.
Limiting the wireless transmit rate: Limiting the wireless transmit rate can help improve range and connection stability. Most wireless cards have the ability to limit the transmission rate. To change this property in Windows, go to the Windows Control Panel, open Network Connections, and double-click on your wireless card’s connection. In the properties dialog, select Configure on the General tab, then choose the Advanced tab and select the rate property.

Wireless client cards are usually set to automatically adjust the wireless transmit rate for you, but doing so can cause periodic disconnects when the wireless signal is too weak; as a rule, slower transmission rates are more stable. Experiment with different connection rates until you find the best one for your environment. Note that all available transmission rates should be acceptable for browsing the Internet.

I’ve installed this new router and some of my network clients (computers, game consoles, etc.) are now unable to connect.
Your new router came preconfigured with a network name and password. That information is printed on a card attached under the foot of the router. All clients must use this network name and password to connect wirelessly to your router. Find the network settings on your client, select the network name printed on the card from the list of available networks, and enter the password when prompted to join the wireless network.

Does the router support Wireless Protected Access (WPA) security?
The router ships with WPA/WPA2 security turned on. Windows XP and some older network hardware may require a software update to support WPA/WPA2.

I am having difficulty setting up WPA security on my router.

Log in to your router by visiting “http://router/” or “http://192.168.2.1” with your web browser. Click Security under the WiFi heading; you should now be on the Security page.
Under Security Mode, select WPA/WPA2-Personal (PSK).
Select WPA/WPA2 from the drop-down menu under Authentication.
Enter a password (8–63 characters) or a 64-digit hexadecimal number (using only numbers 0–9 and letters A–F).
Click Save to finish; your wireless connection is now encrypted.

Notes: If you are configuring the router over a wireless connection, you will have to reconnect after changing any security settings.Some older networking hardware supports only WEP encryption; if older computers cannot connect, try 128-bit or 64-bit WEP or seek software updates from their manufacturers.

I am having difficulty setting up Wired Equivalent Privacy (WEP) security on my router.

Log in to your router by entering http://router/ or “http://192.168.2.1” in a web browser; click Security under Wi-Fi heading.
Under Security Mode, select 128-bit WEP option.
You may type in a WEP key manually or generate one from a passphrase.
Click Save to finish; your wireless activity is now encrypted.

Notes: If configuring over a wireless connection, reconnect after changing any security settings.Some older networking hardware supports only 64-bit WEP encryption; if older computers cannot connect, try 64-bit WEP.A drive I plugged into the USB port is not showing up on my computer.

Try unplugging and plugging it back in; check that it’s firmly connected.
If your drive has an optional power supply, use it while attached.
The router supports FAT16, FAT32, or NTFS formats; drives in other formats will not appear.

A drive plugged into the USB port is not coming on or remains on only for a short time.
Some drives require more power than provided by the router’s USB port; use an optional power supply if available.

A printer I plugged into the USB port is not showing up on my computer.

Try unplugging and plugging it back in; ensure it’s firmly connected.
Install that printer’s driver on your computer.
Check that auto-connect is selected in USB Print and Storage Center.

A different sort of USB device that I plugged into the USB port is not showing up on my computer.
Most USB devices other than storage drives and printers must be accessed via USB Print and Storage Center.

Try unplugging and plugging it back in; check that it’s firmly connected.
Open USB Print and Storage Center; check if it appears in available devices.
Select it and click Use; it will be virtually connected until you choose to stop using it or another person requests use of it.
