I have a strange problem... I am able to connect to Wireless network but not able to connect through the ethernet cable to same network.
I am not able to renew my IP address with ipconfig /all or inconfig /release/renew

I tried rebooting my router but it doesn't help.
I am using belkin router. I don't want to go for hard reset and re configure the router.

Is there anything I can do?

See below:-
I am confused.

Are you sure your ethernet adpater is working? Do you get a light on it?

Yes I get the light... near the ethernet cable...

Can you try pinging out?

Did you turn off your wireless radio?
