[ubuntu] Problem with WPA2 support in Jaunty...

http://ubuntuforums.org – Hello! I am brand new to Ubuntu and so glad to be out from under the crushing weight of Windows! I am very excited to learn about this OS, but I need some help. When I try to connect to wireless networks with a WPA2 encryption by right-clicking and entering the network information, NetworkManager tries to connect, but never quite makes it, and asks me for the password again. When I try to left-click and click a network, the dropdown menu doesn't even have a WPA/WPA2 encryption option. I have already tried installing wicd (didn't work), and uninstalling NM and re-installing also to no avail. I have also downloaded all of the updates I could find. Any ideas? Thanks! (HowTos)
