    Have you tried (and is it possible) installing an older kernel-firmware?

    I have locked mine to 20190118-lp150.2.12.1

    I could not find anything specific on the hardware side. I have now decided to plug in a USB dongle which work on another installation. Strangely, the dongle does not work.

    Here is how far I got with the dongle:
    Code:
    sudo ip link set wlan1 up
    brings up the interface.

    Code:
    sudo iwlist scan
    now lists the wireless networks.

    Code:
    nmcli dev wifi con mywifi password key
    Error: No network with SSID 'mywifi' found.

    As the wifi device nodes are present, and you can apparently scan successfully for available wifi networks, it should be possible to connect. Are you sure that the typed SSID was correct? As you have two wifi devices connected, are you sure that they are both compatible with the wireless protocol used by your AP? It would be nice for you to post the scanning output with us to see for ourselves as well. You can also use the following command to get that information...
    Code:
    nmcli d wifi list
    Try creating a connection profile like this (and choose the preferred wifi device explicitly eg wlan1
    Code:
    nmcli c add type wifi con-name <name> ifname wlan1 ssid <ssid>
    then add the credentials...
    Code:
    nmcli c modify <name> wifi-sec.key-mgmt wpa-psk wifi-sec.psk <password>

    I could get the dongle working by blacklisting the kernel module for the internal wifi (rt2800pci).

    Still, help to get it working would be appreciated. The internal wifi seems to mess enough with the system so that the dongle cannot be activated although it works fine when alone.

    Default AW: No Wifi after reinstall of LEAP 15

    Do you try to unblock the wifi with an key-combination?

    I mentioned earlier in the thread that I have tried everything in this regard (switch/Fn-Combo/Bios). My current diagnosis is a regression in the driver or firmware The hard block is merely a symptom. This is due to the fact that blacklisting is required to get the other wlan adpator to work. I am a bit pessimistic that the issue can be solved as the driver is probably not used by many any more. It would be nice to report somewhere, though.

    Default Wake Up WIFI

    We have the same issue here after a fresh install. No WIFI Network on taskbar.



    1.Yast>System>Network Settings>Network Setup Method>NetworkManager Service>If properly set, switch to wicked and switch back to NetworkManager.


    This operation triggers the WIFI network on taskbar here. SWITCHING TO WICKED REPRODUCE THE EXACT PROBLEM THAT WE HAVE AFTER A FRESH INSTALL: No WIFI Icon ON Taskbar.


    The same can be done during the fresh install in the Installation Settings Page or Menu>>Network Configuration=Switch from one to the other> Wicked to NetworkManager.


    This method is always working.


    Other way around to wake up the WIFI


    2.Yast>System>services manager:
    3. Network Manager = Start/on boot
    4. systemd-networkd = Start/manually
    5.Apply chages and restart to see if it works.
