I have tried almost everything including this one, none of them worked. My macbook pro 15″ is still not connecting to any secured wifi routers… Curse that

renew your dhcp lease
remove your preferred wifi-connections
delete your stored network passwords (keychain)
restart and reconnect to your wifi-connection
done.
