I am helping a friend who had windows 7 on his laptop and everything Wireless Networking worked perfect. He uses his cell phones mobile hotspot as his primary internet. He got a copy of Win 8 through school and decided to use it. After the instal he could no longer connect to the phone hotspot. He then went back to Win XP as he missed placed his Win 7 disc. Same issue happening. Can see all SSIDs but will not connect. I brought over a liveUSB of Ubuntu and WiFi worked perectly. We found his Win 7 disc and reinstalled however the computer will only connect to routers and still will not connect to my hotspot. I know my hotspot is fine as I connect everything else to. I have uninstalled and reinstalled the OS, drivers, hardware and the device will work fine with Linux but not Windows of any flavor (since trying Windows 8). Please help
