I have been using Atheros Wi-Fi cards for a few years now. I must say they are the best Wi-Fi cards I have ever used. Never had a problem, and pick up way more AP's while wardriving than I ever did with a broadcom based Wi-Fi card or Intel card!!!
Yes and might I add I am still running flawlessly with no connection issues and seeing 6 more access points than before with the CRAPTEL 2915 from around my hood. This puppy also works great for wardriving.
I wonder if my 2915 is what makes the bottom of my m70 so hot? I know the ram is up in there, but that's pretty much it I think. The cpu and gpu are out to the sides as well as the hard drive. Could the wireless card really be getting that hot?
I might have to look into this wireless card though, my intel card is a bit better with the newer drivers but still annoying.
