TP-Link TL-WN727N V3 - cannot scan or connect to anything

Look at the bright side - one more problem fixed in 2013 :)

Confirmed, now it also works for me.

BTW, for some reason I cannot build a kernel with "device runfw".

I added the following to my kernel config:

options IEEE80211_DEBUG
device run
device runfw
device wlan
device wlan_amrr
device wlan_wep
device wlan_ccmp
device wlan_tkip

and buildkernel failed:

I removed "device runfw" from kernel config, leaving everything else  
as is. Kernel built successfully and runfw seems to work as loadable  
module.

Happy end_of_the_year!
