I reformatted

[celluloid hero]

and just re-installed Mac OS X. I want to download Boot Camp and install it but now for some reason I can't connect to my network/internet. When I first used the computer I didn't have to set up any sort of network options or anything, it just ran.

Does anyone know how to fix this? (I've tried Network Diagnostics and all that crap, none of it seems to work)

thanks.
