When the Internet light on your Westell router won't come on, it could be the result of various factors, including the need to check the power supply or to power cycle your equipment. In some cases, a simple reset of the router's settings can help with the Internet connection.
Ensure the power supply cable to the Westell router is connected if none of the lights, including the Internet, are lit. If the cable is plugged in and the lights are still not lit, plug the cable into a different wall outlet. If you are using a power surge protector or other supply source, remove the cable from it and plug it directly into a wall outlet.
Check your modem's Internet connection if the Westell's Internet light is not working. If the modem's Internet light is not lit, unplug its power supply cord for at least 30 seconds. Reconnect the cord and check the Internet light. If the light comes on but the router's Internet light remains out, unplug the power supply cable to the router. Replace the cable after 30 seconds. If you use a cable modem, check your TV for an outage. You can also contact your cable service provider directly to determine if there is an outage.
Power cycling the computer, modem and Westell router can sometimes resolve an issue with the Internet. Turn off the computer and unplug the modem and router. Plug in the modem and allow it to fully load. When the Internet light is on, plug in the router. Wait for the Internet light to come on before proceeding. Turn on the computer and check your Internet connection when it fully loads.

As a last resort, you can restore your router's default configuration to factory settings if the Internet light on the Westell router continues to stay off. Locate the "Reset" button on the back of the router. Use a paper clip or pen to press and hold down the reset button. Hold the button down for at least 30 seconds. Release the button to complete the process. All of the security settings for the router will be erased. You will need to access your router's admin page at "192.168.1.1" in a Web browser to establish new settings, just as you did when you first installed it.
