Has your modem been hard reset recently? if so, it may require that you bridge the modem out to work with the router- ESP. if you use Verizon DSL. If so, contact your ISP, and ask for assistance in bridging out the modem.

double check whether you have the ethernet wires back to front

Reset the router for 30 second.
There is a reset button on the router. For WRT54GC the reset button might be at the bottom of the router. There is a flap that you need to turn around. You will see a small reset button. Press it and hold it down for 30 seconds.
release the button. wait for 1 minute. unplug the power to the router and plug it back in.
wait for 1 minute and see if poer light becomes solid.
If not then try to reset the router again.
if the power light is solid then it is in working condition.
Once you reset the router it will come back to the factory default settings.
You will need to reconfigure the router for Internet connection.
If the pwer light is not solid and keep on flashing then it is not in working condition.

This is a sign of a bad router already, so if its still under warranty you can go have this unit replace from Linksys , since this is already a hardware problem...

If your router's internet light is red it means to say that there's no connection. You really have to call Tesco.
