Belkin router I have connected router to my computer but cannot get the modem light to come on,have tried everything.

Turn everything off, modem, router and computer.

Turn on the modem first and wait for a solid data/connect light.

Turn on the router, give it two minutes.

Still if problem presists you need to reset the router

Wireless light will lit up only if any wireless computer is connected to Belkin's wireless network.
First, connect to Belkin's wireless network that you can scan.
After you connect, try to go online
It ll work...

uploaqd the firmware in the router

Well i think u r right, u must contact to Belkin support team (http://www.belkin.com/support/) or to from where u buy this. If router is in warranty period then u will get replacement.

Try hitting the reset on the back of the router. Normally need a pen to hit and hold down the little button. Although if everything is working whats the point? If you previously had setup your router and have a password on it might be blocking access to the assistant setup.

Perhaps one of your ethernet cables is bad?

When everything is connected, the "WAN" light on your router should go on, as well as the lights for whatever network connections your are using for your computer.

Obviously the cable that you used to connect your computer directly to the modem is working, so try replacing the other one.

Do a powercycle. Make sure to completely turn off the modem, router, after 30 seconds, turn on the modem first then the router.
If that will still not work, perhaps there is a need to update the software of your router.
