I have a wireless network in my home and use it with my laptop computer. My desktop is connected to the router and the modem and works fine. My laptop is able to pick up the network and shows excellent connectivity but cant connect to the internet. When I try to repair the connection it says unable to renew IP address. When I go to the command prompt and try to do it manually it says
An error occurred... no operation can be performed on a local area connection while it has its media disconnected.

I know someone changed the network key but I think I changed it back and it still gives me this message. Is there anyway I can find the network key on my desktop computer?

Any help is greatly appreciated.

Thanks
