I just installed a a dlink 520+ into a dell dimension 2100 PC. driver installed correctly. i can see wireless connections, i can see my SSID, i can connect to it. I can see the IP, subnet, etc, signal strength is good, but i cannot connect to the internet. here is what i have tried.

Using Dlink's own software and disabling windows:

I put a my laptop right next to the PC and saw the wireless, and internet works fine.

Any ideas?
