User:Trickygnome/wifi low level configuration

Steps:

 - down: iw dev wlan0/mon0 del (optional), stop and kill wpa_supplicant
 - rfkill unblock wlan
 - iw phy interface add wlan0 type managed (optional)
 - restart dhcpcd, restart wpa_supplicant
 - wpa_cli set_network $nid bssid/ssid $SSID
 - wpa_cli set_network $nid key_mgmt/psk NONE/$PSK
 - wpa_cli enable $nid

Note: Well, maybe it will easier to use sed commands at /etc/wpa_supplicant.conf instead of wpa_cli.
