Problem with Wireless Adapter in Kali VM

Hi everyone.

This is my first post here in null-byte, though I've been exploring it in the past months, getting to know the basics and some quick exploitation tips hehe. Very very cool site

Well I installed a virtual guest of kali linux in virtual box with an image specific for virtual box. I've fixed the repositorys folder and got update and upgrade etc. My problem rises when I try to get a wireless interface.

One of the first posts I read was the one on linux instalations (linux ultimate portability guide or something similar), and it said I would need a wireless adapter in order to get a wireless interface in a virtual guest. So I bought an alpha adapter following the recommendations from OTW's post on the subject - thanks for all the work you putted in this site btw, making computer security knowledge more accessible to people like me. But once I plug in the wireless adapter, and try to enable it using the devices tab in the box, the box freezes. I'm incapable of shuting it down, even when I end the virtual box tasks in task manager, once I start Virtualbox again it just says the box is shutting down.

I've been trying to fix this for the last couple of days, and I thought that maybe one of you would know if I'm doing something wrong, or maybe point me in the right direction.

Thanks in advance, and again thank you for the awesome site.
