I recently purchased a Alfa AWUS036H, and I have yet to get it to work.
I've tried installing both the 100mw and 1w drivers on Windows 7 with nothing. I have tried installing them on Backtrack 4 R1 by running the CD in Wine and installing "Windows Drivers".
On top of that, I can't get Backtrack in VirtualBox to find any wireless connections. I find them fine outside of it in Windows 7. I've went to Network options and picked nearly every combo I could with no luck.
If anyone could help, I would appreciate it. I've searched, and I almost feel I have a faulty Alfa. But if so, I still need to know how to get WiFi in VirtualBox without the adapter.
Try importing the BT .vmdk in VirtualBox then go to Settings, networking, and select Bridged network than choose your adapter and it should work.
