Because I screwed up something on my homebuilt Windows 7 64-bit machine and I'm not sure what. It seems to be running fine after a BIOS update and some scanning with Norton Utilities, but I can't connect to our wireless network. The network is working (I'm on it with my laptop) but while the system says I'm connected to the network and have internet access, I can't get anywhere on IE or Firefox.

The best I can figure it is a software or BIOS setting that I'm missing. I can't wait to get a Mac...
