The following was taken from http://www.debianadmin.com/enable-wpa-wireless-access-point-in-ubuntu-linux.html Normally, I would never repost content from some else’s site, but I’m afraid that it may disappear at some point. So, I’ll post it here. Again, I DID NOT author this content, but I’m puting it here for archival purposes just in case it disappears.
Procedure to enable WPA Wireless in Ubuntu
To update the source list run the following command
sudo apt-get install wpasupplicant
sudo apt-get install network-manager-gnome network-manager
sudo gedit /etc/network/interfaces
Comment out everything other than “lo” entries in that file and save the file
Create a file called /etc/default/wpasupplicant, add entry ENABLED=0 and save the file
sudo touch /etc/default/wpasupplicant
Reboot your system or use the following command
sudo /etc/init.d/dbus restart
Once you login back in to your machine you need to left-click the network manager icon in Gnome and select your wireless network It should prompts for password, type, etc and It will ask you to choose a password for your new “keyring”.
After enterring all the details my wireless network was connected and working fine you can see in the follwoing screen
Again, special thanks to the folks at DebianAdmin.com for providing us with this elegant solution.
