Actually I don't think my patch disables that functionality. If there're multiple AP with the same essid "foo" and one of them has MAC "00:...:ff", then: iwconfig wlan0 essid "foo" This will make the station associate with the first AP with essid "foo". iwconfig wlan0 ap "00:...:ff" This will disassociate from the previous AP, and then associate with the first AP with MAC "00:...:ff". Am I missing anything here?

If you want to connect to an AP with the SSID "foo" and the BSSID "00:...:ff" you need to make two calls, e.g. iwconfig wlan0 essid "foo" iwconfig wlan0 ap "00:...:ff" Your patch disables that functionality. johannes ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
