Thread: unstable wifi connection using wicked

  1. #1

    Default unstable wifi connection using wicked

    Can't establish new connection (web browser, mpv was used) sometime. Active connection are ok. Restart of wicked is needed.

    only this was in log:
    Code:
    Jan 18 18:00:00  dbus-daemon[1075]: [system] Successfully activated service 'org.opensuse.Snapper'
    Jan 18 18:00:00  dbus-daemon[1075]: [system] Activating service name='org.opensuse.Snapper' requested by ':1.>
    Jan 18 18:00:00  systemd[1]: Started Timeline of Snapper Snapshots.
    Code:
    Network controller: Intel Corporation Centrino Wireless-N 135 (rev c4)
        Subsystem: Intel Corporation Centrino Wireless-N 135 BGN
        Flags: bus master, fast devsel, latency 0, IRQ 34
        Memory at f7c00000 (64-bit, non-prefetchable) [size=8K]

        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi
    Other device connected to same wifi AP works fine.

    Anyone know please how to make connection more stable ? It has never happened in Leap 15.1 and earlier AFAIR.

    Are you referencing the "mpv" media player?
    Are you trying to connect to a video stream?

    What error displays using any particular app? If you launch from a command line console, you may see an error.
    If your graphical application has already launched and fails in any way, there is usually some way an error displays, eg in a web browser in the bottom left margin (if you have that part of the web browser enabled). Of course, if you have a problem using a particular web browser, you'll have to identify which one you're using.

    And, if you are invoking your application after you login and started your user session,
    - Did you verify your network connectivity using the standard tools ping and route??
    - You can view any events and errors in real time if you open a console before you try to connect using your application, run the following command and leave it open
    Code:
    journalctl -f

    It does not happen every day.
    No info in dmesg, journalctl.
    No need to reboot Leap.

    The choice of network manager should make no difference here.

    You have name resolution problems which means that although your basic networking is working, your system can't query a DNS server to resolve the name of your target connection to an IP address.
    You should diagnose and fix this using usual methods...
    view the contents of file /etc/resolv.conf to view configured DNS servers.
    Ping the configured DNS servers to verify you have a network path to those DNS servers
    Use a utility like nslookup or dig that allows you to query the DNS servers directly, and if your configured DNS servers don't work, try others.

    You can use your imagination why you can't execute a name resolution lookup, eg
    You can't connect to a working DNS server
    You can connect to a working DNS server but it's not responding
    You've been assigned intermittently (overloaded?) DNS servers which return results only sometimes.

    If you you have problems figuring out what to do, post again.
