    Network Manager Applet - Networking Disabled

    Okay so I have been working on this for a couple of days. I have wired network only. My Network Manager Applet says Network Disabled and enable is grayed out. I know that interfaces is setup correctly. I have tried a number of things, most recently uninstalling network-manager-gnome and reinstalling. Any help is appreciated at this point.

    Yeah, it sure is. I removed Connman and all connections failed, including wired. So I think that Connman is working behind the scenes. Also, after uninstalling Connman the Network Manager applet icon disappeared. When I reinstalled Connman (yes, I confirmed Net Man still installed) Net Man icon came back (after reboot). I had connectivity again but still have "Networking disabled" when hovering over icon and icon is gray with red exclamation. Left clicking on icon shows "No Network Devices Available" grayed out. Right clicking shows "Enable Networking" grayed out.

    Are you trying to get wireless enabled or fix network manager. Your wireless interface is disabled.

    Are you sure this is the correct driver ? driver=ipw2200

    Your right, my mistake. I had been making many changes and must have run the ls while it was off (my system has a bright light on the lcd for wireless state).

    I am trying to get Network Manager working. Apologize for the confusion.

    [main]
    NetworkingEnabled=true
    WirelessEnabled=true
    WWANEnabled=true

    I had seen this referenced in the forum. When I looked in /var/lib neither the directory nor the file were there, so I added both the directory and the file myself. Yes, I am new to this.

    ...and networking is still disabled ? That file looks fine BTW.

    Have you tried stopping and starting network manager ?

    Code:
    sudo service network-manager restart
    Kind regards

    Re: Network Manager Applet - Networking Disabled

    $ sudo service network-manager restart
    [sudo] password for sysuser:
    restart: Unknown instance:

    Seemed strange so I tried this
    $ sudo service network-manager start
    network-manager start/running, process 4678

    Stranger still right? BTW, I have the icon on the panel, I can edit connections and I have removed and re-added them many times. Usually after trying something I read.

    Enable Notifications is not grayed out and it is checked. I can also see the about - NetworkManager Applet 0.8.1
