Thanks. Actually, I didn't get anything I believe to be helpful. So, my steps were: # ifconfig zyd0 debug # ifconfig zyd0 up # ifconfig zyd0 scan zyd0: flags=8847<UP,BROADCAST,DEBUG,RUNNING,SIMPLEX,MULTICAST> mtu 1500 lladdr 00:18:6e:35:fd:7f priority: 4 groups:

Where can I read what is "association failed (status 25)" and "deauthenticate (reason 3)"? Does anyone know what the problem is? Thanks in advance. -- Dmitrij D. Czarkoff
