My laptop broke and I always used ICS from my laptop to get internet on my desktop now i need a wlan PCI adapter. I went to a local computer store and asked the guy he said he needed to know what kind i need and as i am new to this i honestly have no idea. So my question is how do i figure out what kind i need? i have an ibuypower nzxt windows 7 64bit amd phenom II x4 955 Processor 3.20 GHz not sure if that matters. Any help is appreciated.
