Setting up a wireless nework connection via command line

Update: These commands only works for unsecured SSIDs, apparently (and obviously).

Having set up a working wireless connection to the network, it was time to get it connected. I decided to use the command line way to connect to the network.

[usr@host ~]$ su -
Password:
[usr@host ~]# ifconfig <interface> down
[usr@host ~]# dhclient -r <interface>
[usr@host ~]# ifconfig <interface> up
[usr@host ~]# iwconfig <interface> essid "<essid_in_quotes>"
[usr@host ~]# iwconfig <interface> mode Managed
[usr@host ~]# dhclient <interface>

How I Got My Wifi Running Consistently on PC-BSD 8.0

Had a hard time looking for the way to setup Wifi on my PC-BSD 8.0 installation. After much navigation, I found it nestled within System Settings -> System Network Configuration.

So I did my configuration here and expected Wifi to connect instantly with no problems. And it connected, for at least 5 mins. then it cut-off and after a few seconds it connected again only to disconnect after 20 secs. (or less). In other words, it was giving me intermittent connection.
