Linksys wireless router (ERT54GH) Wifi light is off.. Power is working..How can i fix it ?

Solution
Just be aware that the router you have chosen has limited range compared to some more expensive ones. Dlink says it is ideal for apartments and small homes. If you live in a small apartment it may be enough, but a larger house and this thing is going to leave you with dead spots, especially if across multiple levels.
Before I would call the router a goner I would try a few simple fixes:

1- Reset the modem as well.
2- Plug the computer directly into the modem and make sure the internet signal is present.
3- Try a different Ethernet cable, and make sure it clicks fully into place.
