XR5 w/Gigabyte WLAN Owners - PLZ HELP!

Ok I really need some help. I just did a clean install, installed all drivers, and let windows update everything. I did not install McAfee, instead I am using avast free. Everything seemed fine, and my wireless connected, and downloaded the windows updates. After installing avast I restarted and it didnt full boot. It did the vista loading screen, then went black. I waited 5 minutes, then turned it off with power key. I then started back up, and it booted no prolem, and avast updated itself. So all was well.

Then I got onto my work computer, which is connected to the same network ass my wireless, through ethernet. I could see my xr5 in the networked computers windows, and was able to access a shared drive aswell. I tried streaming a movie over the network, that was located on the shared drive on the XR5. as soon as I opened the movie on my work machine, the XR5 did the same thing it has been doing when interacting with other computers over wireless. It froze. I waited a while, and turned it off.

Can someone with the 9262, who has the Gigabyte GN-WS30N mini WLAN Card, PLEASE try and access shared files stored in the XR5 from another computer, and if possible, try and stream music, or a movie, or just transfer something. It seemed to work when I used the XR5 to access files on another computer. It freezes the other way around only.
