Ubuntu: Unable to connect to wireless internet(wifi) through KDE plasma desktop


I installed the KDE plasma desktop through Ubuntu software center. I am on Ubuntu Lucid Lynx.

After the install, I'm unable to connect to my WiFi connection in the KDE session. But I can connect to my WiFi perfectly through GNOME session. I've tried a lot without much success. Also KDE doesn't store my password correctly and keeps prompting for authorization again and again.

  • Some of the things that I noticed:

    1. Network is detected, Network name and strength is also displayed. Other characteristics also appear properly.
    2. When the credentials are supplied, it accepts them and continually displays the message "Setting network address". However this process never succeeds.
    3. At this stage the password is repeatedly asked many times but the connection is never established.
  • Some of the other things that I did:

    1. I have also tried other things like restarting my modem and the computer. That didn't work.
    2. I tried to restart nm-applet and KNetworkManager. That didn't work either.
    3. ifconfig display all my interfaces and Mac addresses correctly.

Since it's working fine GNOME the drivers are fine. This is sure a KDE specific issue. Other threads related to this on the interwebs don't offer much information either.

Please share a solution for this.


Try wicd

  1. To install

    sudo apt-get install wicd  
  2. Then set KDE to use wicd on: SystemSettings â†' Information Sources
