Connect to WiFi network using Mac Terminal
As of Snow Leopard (Mac OS X v10.6.x) and possibly earlier, you can do:
networksetup -setairportnetwork $INTERFACE $SSID $PASSWORD
Where...
$INTERFACE
is the "enX" style identifier for your AirPort card (usuallyen1
, but it'sen0
on MacBook Airs anden2
on Mac Pros, and can vary for other reasons as well)$SSID
is your network name, such as"Simon's SSID"
. Enclose it in quotes if it contains spaces.$PASSWORD
is your WEP, WPA-PSK, or WPA2-PSK password.
If you look at the man page or help/usage statement for networksetup
you'll see that it has other AirPort-related subcommand for getting or setting the power state (AirPort card on/off), and for managing the Preferred Networks list and 802.1X profiles (if your network uses 802.1X, such as a WPA Enterprise or WPA2 Enterprise network would).
Figured it out:
sudo airport -A
Here is a little guide on using airport in the Command Line
Apparently you can use
$ airport
as a command. I would try
$ airport -help
and see if it brings up some options.
