I have a pair of TPLINK TL-WN722N that I am using with Kubuntu 11.04.

If you want to use the new firmware then you need to install 
compat-wireless.

So I had a few issues with the stock 11.04 ath9k_htc driver and putting 
the devices into AP mode. Even when in managed mode I was getting a very

devices have been humming.
