Thread: USB WiFI Adapter no regocnized after reboot

  1. #1

    Red face USB WiFI Adapter no regocnized after reboot

    Today a ran into a problem. OpenSuSE 15.3 fully updated, I rebooted the system due to new kernel update.

    NetworkManager did not show any WiFi Adapters. I tested around with Modemmanager, other USB WiFi-Adapter, nothing worked.
    The Adapter was shown in lsusb, but ModemManager did not show up anything.
    First I thought that is is related to kernel, udev or dbus, but that is not the case

    After hours of research, I found the solution here:
    https://www.suse.com/support/kb/doc/?id=000016939

    Results that the latest update activated that unsupported modules (not flagged as supported by SuSE), will not be loaded unless
    you allow unsupported modules.

    You may test journalctl -f, the plug in the Adapter, and look again. If it tells you that there is an unsupported module, the above link does the work.
    set 'allow_unsupported_modules 1' in /etc/modprobe.d/unsupported-modules

    After that change, NetworkManager could see the adapter and everything works again.

    Default Re: USB WiFI Adapter no regocnized after reboot

    I applied that kernel update on Monday. When I rebooted, I had no network (I am using "wicked").

    I tried
    Code:
    systemctl restart network
    That did not help.

    So I rebooted. My intention was to boot the previous kernel. But, due to a slip of the finger, I rebooted the same (newest) kernel. And this time, I had a running network.

    I'm not sure what went wrong. I will be watching closely for the next few reboots. My next planned reboot is tomorrow.
    openSUSE Leap 15.4; KDE Plasma 5.24.4;
    testing Tumbleweed.

    Hi, I tried previos kernel too, no efect.
    And I tried also change to wicked, but USB-WiFi where not recognized.

    Did you try to enable unsupported modules ?

    Is that just a reference to kernel-default-extra? I do have that installed.

    No, I had kernel-default-extra and kernel-default-optional installed before this issue

    Installation of kernel-default-extra automatically enables loading of unsupported modules, you do not need to do anything.

    Exclamation Re: USB WiFI Adapter no regocnized after reboot

    This is what I did from Opensuse 15.2 a few weeks ago:

    zypper --releasever=15.3 ref
    zypper --releasever=15.3 dup --download-in-advance

    Update was working excelent, no problems, everything worked well, also USB-network.

    About one week there have been no problem, everything worked well.

    But, updating from kernel 5.3.18-59.16-default to 5.3.18-59.19-default, and then rebooting, unsupported modules got disabled without doing nothing.

    Don't know why it happened, the required packages all where installed before, I should have worked.

    I use Linux since Suse 5.3, but I have no idea why this happened.
