Yes, that's exactly what I tried to do. From what I read from the man page of iwconfig, I thought iwconfig wlanx ap <mac> should be enough to connect to an ap without specifying the essid. Maybe I didn't understand the correct usage of iwconfig. However, one of our test cases failed because of this: Steps to Reproduce: 1. set up the SSID name with Open/None in AP 2. reload the driver 3. interface up 4. send the command 'iwconfig wlan0 ap <MAC address of the AP> Expected Results: the association is established successfully.

Hmm, so setting the ssid to NULL would make it impossible to connect to any network, no? I don't think I understand what you want to achieve. Are you, by any chance, trying to get it to connect to an AP without ever specifying an SSID? That can't really be supported (nor ever was by mac80211). johannes ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
