I recently replaced Window8 with Windows 7 Ultimate (64bit, as I couldn't get on with Windows 8). The installation went okay until it got to detecting wireless devices. Absolutely nothing! This is a 100% legitimate version. I couldn't register it, because I could not get the Internet. What is even stranger, is I purchased Windows 7 Premium at the same time for my laptop. That version turned wireless off, and I had hell's own job getting it back again. As I needed a computer for my work, I installed Linux Ubuntu on the laptop, and that worked fine on wireless, so no problem there. The desktop also works okay on wireless dual booting with Linux Mint, but Windows just does not show any sign of a wireless device. There are at least seven other hubs in the area as well as mine, and they all show up on Linux, but nothing on Windows. What on earth is going on please! I do need Windows for some of my work.
