Wich I found out by myself and didn't read somewhere e.g. at http://wireless.kernel.org/en/users/Drivers/iwlwifi . If it's that clear and obvious, why not state it there? I would have saved me 50 Euros and some hours...

Well, I have although I would have no idea where you could buy it. As
you may guess it is a Broadcom device and comes with my job.
