I recently purchased a Gateway NV7921u and the first thing I did was install Win 7 Ultimate on it as this is what I have on my other PC's. For some reason, now the built-in webcam does not work, the multi-gesture touchpad only utilizes one finger, only half of the touch-sensitive keys work above the keyboard and, most importantly, I can ONLY get on the net WIRELESSLY. If I plug in an Ethernet cable and hardwire it I lose my connection entirely and it is driving me bonkers. Gateway says it is a driver issue so I click the link for say, the webcam driver or the WAN driver and download them (I also use a program called driver detective that does this for me), the driver(s) don't even show up anywhere! Help!!!!!
