Hello guys OK I'm gonna give it straight to you guys I have an old GX 159 Dell Desktop I tried to install Ubuntu 10.10 on it and it worked like charm the problem is when I connect my Alfa 1 wireless adapter and connect to the network it won't let me connect to the internet. Well I have been succeeded to connect to the weather center, but I can't update or open the Internet even if I have been able to open Hotmail.com after 2 minutes it won't open anything after that

Note: I didn't install the driver for adapter and I don't know how to do it because I tried before and I failed adding I used it on more than one distro. By the way it works perfect on Windows so any idea???
