I recently bought a USB 3.0 Wifi adspter for my PC. It is a netgear n6210. It was working just fine with Windows 10 but I had to reinstall Windows 7 and re-upgrade to Windows 10 again. After I did that, my PC detected the adapter, but couldn't connect to the internet, so I reinstalled windows 7. Now my PC doesn't even know when I have it plugged in. I have tried every USB 3.0 port on the computer and have installed drivers from the CD multiple times.
