"Other then MS doing it's usual hissy fit over it not being MS approved, no bumps installing and it came right up afterward. Was using it with a cheap USB wifi stick. Took seconds to connect to the net once it was loaded. Still have more options to try out, but it's already done everything I needed.

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.
