 loss of connectivy in wifi mode.
the computer is connected to the Access Point, but when I try to download a file or visit a web page the speed connection decrease to 0kb/sec.
After a few seconds (5-10) the connection speed return to 5-10 kb/sec for 2-3 seconds, but then the speed decrease to 0kb/sec.
Using on the same notebook windows 7 with the same acces point the wifi card works great.
