I cannot renew my IP address.. What can I do help!? Ive tried to repair the connection. Ive also plugged and unplugged the modem. I also tried start/run/cmd/ipconfig and Start Menu -> Run -> ipconfig /renew... didn't work. p.s I have a linksys modem.

You could try the repair button, right click on the little icon at the bottom that shows you are connected and click on repair, if that doesn't work then re boot the router. Just a thought

Is the router configured as DHCP? Please give us more info to work on, thanks.
