computer sees airport, but can't connect

[trp_m]

O.K., my computer is connected to an airport base station over LAN and can't connect to the internet. I run the Airport Admin Utility and the computer can see the airport, but I can't get the thing on the internet. I ran iTunes on it and another computer connected wirelessly (witch can get on the internet) and no shared music either. I've also fiddled with the Network Prefs every witch way I can think of. I just don't get it. Any advice would be appreciated. Thanks in advance.

Are you using DHCP? I'm going to assume you aren't connecting via WLAN to the router ("is connected to an airport base station over LAN")
Since one can get on the 'net and the other can't, it sounds as though your ethernet connection isn't set up to recieve an IP address automatically.

Go to network prefs-> ethernet-> and make sure the DHCP protocoll is activated...

Yeah, everything was set up correctly, I have no idea why it wouldn't work. Ended up resseting it to factory settings and setting up everything over again. Thanks anyway.
