I have this wireless card, works fine for months, now having major issues with it connecting to my network. It won't obtain an IP address, I can set a static one but that doesn't work properly either, it says it is connected but it is brutally slow. I tested the card in another computer and I know it works fine, also did a fresh install (tried XP x86 and x64 versions), still the same problem. I tried resetting my router but to no avail, my Macbook works fine though in OSX and XP x86. Any ideas?
