** Description changed: ar9170usb kernel module is crashing when used for TP-link TL-WN821N usb wifi card. If I remove it then it causes system crash, kernel panic. - The bigger problem is: wifi net connection is very unstable. Losing connection in every few minutes. - Connection speed is low, less than 100 kbps, many ip packages are lost. - Sometimes strange ssid is shown for AP with strange characters. In this case it can't connect of course. + The bigger problem is: wifi net connection is very unstable.

In this case it can't connect of course. This problems was detected, then TP-link TL-WN821N was connected to a Belkin 54g access point. (WPA-PSK TKIP) However there is no problem when it connects to La Fonera fon2100a (WPA2-PSK AES). There is no any problem to connect to same Belkin 54g AP on Windows, from same computer and same TP-link TL-WN82N.
