Boot Up - Wireless Network Auto Connect - Burden

Asked by SteveLW

Hey there,

When I boot up my Linux Ubuntu Gutsy Gibbon, it almost always auto-connects to an unsecured wireless networks "A" or "B" in my neighborhood instead of the secured wireless network "C" in my home. The computer does not remember to connect back to "C" each time I boot. How do I change this? Any help is greatly appreciated. Note that I will need step-by-step instructions and I am no Linux guru who can fix something with a short response that tells me to change a configuration file.

Thanks all!

Steve

Hi !

in the NetworkManager configure dialog, you have to remove the networks you do not want to connect automatically from the list of saved networks.

Hello,

There is nothing on my computer that I can find that says "Network Manager." Under the System / Administration menu, I have "Network" and "Network Tools" which I don't see the dialogue you describe. How do I get to Network Manager? Is that a bundled Ubuntu utility out of the box or something special I have to add in ???

Just right click on the network icon in your systray : that is NetworkManager

Thanks, I found the four blue bars icon in the system tray bar which now is see is an applet for NetworkManager. When I right click, I see options for "Enable Networking", "Enable Wireless", "Connection Information", and "About." Clicking on "Enable Networking" toggles networking on and off. Clicking on "Enable Wireless" toggles wireless on and off. Clicking on "About" shows "nm-applet 0.6.5". Clicking on "Connection Information" just shows "Active Connection Information" with no option to change anything. When I *single* click on the NetworkManager icon, I see list of wireless networks in my neighborhood. I cannot find anything or way on how to delete these from a list. Can you tell me more detailed steps?

Sadly, this functionality is not implemented in the GUI interface yet -- you have to delete unwanted networks from the command line. Here is how:

1: Open a terminal.

2: Type "sudo /etc/dbus-1/event.d/25NetworkManager stop" without the quotes and press Enter.
    If you are prompted for your password, enter it.
    This will shut down the Network Manager subsystem.

3: At the prompt, type " gconftool-2 --recursive-unset '/system/networking/wireless/networks/<network>'" without the double quotes, replacing <network> with the name of the network you no longer wish to associate with, and press Enter.
    The single quotes MUST STAY, otherwise spaces or odd characters in the name of the network you wish to delete will cause errors.
    If the command finishes sucessfully, you will be returned to the prompt without a message.
    Repeat the above command multiple times with different network names if you want to delete multiple networks.

4: Type "sudo /etc/dbus-1/event.d/25NetworkManager start" without the quotes and press Enter. This will restart the Network Manager subsystem.
    NetworkManager should no longer associate with your unwanted networks.

Sorry I misanswered : this is a functionality of Knetworkmanager wich is the equivalent applet for KDE, and I assumed that the same option was available in GNOME

Can you help with this problem?
