Can't configure wireless now that WPA2 is enabled!
I made this one: How to connect and disconnect to a network manually in terminal?
But i think it won't work since i later found out that when you put a WPA key, the whole thing gets a "little" complicated. Not so easy as iwconfi wlan0 key s:password for like WEP security. I then found out this HUGE post which has in detail information that worked in my case for WPA and WPA2 using PSK (At least in my case) I hope it helps you too:

NOTE: Make sure your card supports WPA. Happen to one of my students that he spend a week trying this and it did not work since his card did not support WPA (It did not even have anything WPA related).

I had removed network-manager as soon as I installed Ubuntu 10.04.
Earlier I used to do the following to connect (successfully) on command line:
iwconfig eth2 essid NASA
dhclient eth2
Now that WPA2 encryption is enabled, I tried this, but failed:
iwconfig eth2 essid NASA key hunter2
dhclient eth2
with error:
Error for wireless request "Set Encode" (8B2A) : invalid argument "hunter2"
Where am I going wrong?
lspci
gives:

In the command:
sudo wpa_supplicant -D wext -i eth2 -c /etc/wpa_supplicant.conf
I used wext as the driver.When I run this command, the following happens:
Trying to associate with 00:24:b2:39:f4:c6 (SSID='NASA' freq=2462 MHz) ioctl[SIOCSIWAP]: Device or resource busy
Association request to the driver failed

If by any reason you think this question is still viable or useful in anyways or that there is still a good chance it will be answered please flag it to a moderator or add a comment with the reasons why you want it reopened. Thanks!
