I have installed W8 recently, but the problem is that computer does not recognize wifi adapter (alfa AWUS036H).
Computer recognize other devices, for wifi says you have to plug in ethernet cable. I tried adapter on laptop for problems, but there was working.

See if you can find a driver that will work here (http://www.alfa.com.tw/in/front/bin/ptlist.phtml?Category=105397).

I've tried this already but it doesn't work.
Guess I'll have to wait until official release.

There are many devices that the manufacturer's have not provided updated drivers yet. Hopefully shortly for many as the Win 8 code is nearing completion.
