After the update yesterday I can't connect to the wireless. Wireless is working fine on other devices (Windows pc, iphone etc.). I tried the basic solutions, turning airport on/off, changing networks, restarting mac. Is there any simple solution why it happened? I am thinking of 1) restoring mac to the backup from the time machine 2) restoring it to factory settings?... would it change anything?.. Any comments greatly appreciated. Btw, I am not an advanced user.
