Ubuntu: WiCD Network Manager “Connection Failed: Bad Password” [SOLVED]
If you’re familiar with correctly entering your WPA2 password after an Ubuntu update and now your Netbook won’t connect using WiCD, I got the solution that worked for me.

Uninstall network-manager and restart WiCD
Open a terminal and type:
$ sudo apt-get remove network-manager ... $ sudo /etc/init.d/wicd restart
You may have to restart wicd daemon twice in case you don’t see the wireless networks right away.

dude…you rock. I pounded my head against my keyboard for 45 mins wondering why i couldn’t get that to work. I uninstalled network-manager from the Ubuntu Software Center and installed Wicd manager so i thought it was already uninstalled.
Kudos to you my friend.

FOR ANYONE LOOKING TO DO THIS, BE WARNED IT DOES NOT WORK FOR ME. NOW MY COMPUTER DOESNT EVEN IDENTIFY AN WIRELESS NETWORKS. DO THIS AT YOUR OWN RISK. IT COULD WORK OR IT COULD SKREW UP EVERYTHING. THE RISK IS YOURS…
