I have this TP-LINK TL-WN821N Stick, and I want to get wireless with it. But I dont really know wich module to load. The only two modules i can find wich could be the right ones are ar9170usb and ath9k_htc . When I load them with modprobe, and i type in iwconfig there is still no wlan0 .
Somebody told me I had to load ar9271, but where can I find it. How can I install it, and is it really the right one?

Please help me.
Thank you for answers
