I recently bought a TL-WN951N PCI card, it gets detected right and the module being used is ath9k.

When trying to set it to master mode however, it prints:

$ iwconfig int1 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device int1 ; Invalid argument.

OS (from uname -a): Linux foo 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux

Anybody knows why?

If you want to answer your own question, just post an actual answer and accept it as the working solution later. Please don't put any solutions into your question :) – Oliver Salzburg Oct 10 '12 at 13:04
ok, thanks, I will do it – f0o Oct 10 '12 at 13:22

Well, apparently newer wireless-tools requires hostapd in order to set an wireless extension in Master mode. They also deny manual setting of the Master mode for some reason.

So I guess it's "Solved"
