My laptop's Wi-Fi hardware has stopped working no matter what I've tried. I suspect an old driver (there were no new updates). I installed it and my wifi is back. Not only that, I can work with both 5.0 and 2.4. When my wife had the same problem (same brand laptop) I bought her one and that solved the problem too. I would recommend that now. Oh, Bluetooth was an added bonus.
