Thread: wlan0 is not working with NetworkManager, but works fine with ifup.

  1. #1

    Default wlan0 is not working with NetworkManager, but works fine with ifup.

    Hi All!

    I have a problem: I made office wireless network working (WPA-PSK) with few clicks in yast, but it's not working with NetworkManager at all, no matter what I tried.

    My configuration:
    OpenSUSE 11.4, KDE 4.6.1 from releases, kernel (tried both default and desktop), installed all intel-wireless related packages (detected as Intel 6000 family).
    Dell Latitude E6410.

    Here is the NetworkManager log, message repeated forever:
    Code:
    Mar 25 12:03:00 sbaiduzhyi NetworkManager[11651]: <info> (wlan0): supplicant interface state:  starting -> ready
    Mar 25 12:03:00 sbaiduzhyi NetworkManager[11651]: <info> (wlan0): bringing up device.
    Mar 25 12:03:00 sbaiduzhyi NetworkManager[11651]: (nm-device-wifi.c:3782):real_set_enabled: runtime check failed: (priv->supplicant.iface == NULL)
    Mar 25 12:03:00 sbaiduzhyi NetworkManager[11651]: <info> (wlan0): taking down device.
    Here is the /var/log/messages at exactly same time:
    Code:
    Mar 25 12:03:00 sbaiduzhyi NetworkManager[11651]: <info> (wlan0): supplicant interface state:  starting -> ready

    KDE NetworkManager plasmoid reloads about 3 times a second, making any context menu in system tray absolutely unusable.

    Try this first:

    Configure and use Networkmanager-GNOME in KDE4 to avoid serious issues with WiFi/UMTS.

    And then reply if it helped. Helps in a lot of strangely different setups and situations.

    Best regards.

    Hello,

    did you configure kwalletmanager?, its necessary to handle WiFi keys for Networkmanager.

    From KDE menu System Settings -> Account Detail -> Wallet

    Regards

    kwallet is enabled and configured. Looks like it's really problem with kde networkmanager. Works perfectly with cnetworkmanager. I don't want to use gnome applet in KDE env, but looks like I'll have to eventually...

    Try the network manager plasmoid first See this thread for reference :
    Knetworkmanager not start on login

    Of course, I worked with plasmoid only since SUSE 11.2. This time I tried default one first, it just showed none of my configured wireless connections. Then I worked with plasmoid - the same story, plus it makes many other plamoids unusable. That's really strange because it worked fine in 11.3 with wired connections...

    This is very strange indeed. I don't experience any of this problems in 11.4 and didn't have them in 11.3 as well. Maybe somethings broken in your install ? How did You upgrade ? What are your repositories ? Did You try this with the default 11.4 KDE version ?

    Thanx for your interest.

    I am using KDE 4.6.1 from Releases, with krusader from playground. Mainly because of *-debuginfo packages. Tryed networkmanager-related packages from playground too, but it didn't got better, so I reverted them back to core. Maybe today will try to create configuration with gnome applet, then will check if KDE's will work with that configuration.

    But did You try with KDE 4.6.0 ?
