Fresh install of 12.04 on a Dell LAtitude E6400 and came up with the wireless issues. I'm fairly new to linux command line, but have been using ubuntu for several years now on a dell D630 so I researched, sudo'd, reinstalled and now the light turns on and off with the external switch and Im able to enable the wireless option in the connectivity settings but it still wont see any wifi networks.

Anyhow I obviously need help to get it to connected.

Here's the results from the following commands:

Laptop connects no problems through the wire, if you look at nm-tools it says the wireless is disconnected. So how do I get it to say connected?

I like to use WICD because it is a simple and easy to use network manager. Its a very good alternative to network manager in Ubuntu and it seems to always work when Network Manager doesn't. To install it just open up the terminal. Now download the latest NetworkManager, in case you need to reinstall it if WICD doesn't work

    sudo apt-get install -d --reinstall network-manager network-manager-gnome 

Then to install it

    sudo apt-get install wicd-gtk 

And now you need to uninstall NetworkManager:

    sudo apt-get remove --purge network-manager-gnome network-manager 

Now you can find WICD in your menu Start WICD, find the network you want to use and enter the information needed, password, encryption, etcetera and choose Automatically Connect to this network. You should be good to go!

WICD may also be available in Ubuntu Update Manager so you can look there first but it is important to uninstall Network Manager completely to prevent conflicts!!

  • Thanking you! WICD worked a treat. Never thought of using a different network manager and now I feel stupid, but I can live with that. Thanks for the help and the quick reply.
