** Description changed: + UPDATE: There is a new open firmware that seems very promising: + http://wireless.kernel.org/en/users/Drivers/carl9170 + 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. 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. The lshw output for this wifi device is: *-network description: Wireless interface physical id: 1 logical name: wlan0 serial: 00:25:86:e5:52:c9 capabilities: ethernet physical wireless configuration: broadcast=yes ip=192.168.2.4 multicast=yes wireless=IEEE 802.11bg TP-Link TL-WN821N is supported since kernel 2.6.31-19 (Karmic Koala), according to this wiki page: https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsTP-Link#USB uname -a : Linux szaturnusz 2.6.32-16-generic-pae #25-Ubuntu SMP Tue Mar 9 18:03:39 UTC 2010 i686 GNU/Linux cat /proc/version_signature : Ubuntu 2.6.32-16.25-generic-pae
