I that that madwifi.org is a Linux specific driver so I have ignored that site up to now. Setting 'countrycode=276' (Germany) allows the usage of the additional channels 12, 13. I found the answer to my antenna question on madwifi.org, too. Basically if 'diversity=1' I should let the hardware / driver select the antennas to use. Regards Markus
