    Default No WiFi card not found after update (RTL8822BE)

    Hi,
    I updated openSUSE tumbleweed today. I now have the 5.17.5-1 kernel but my WiFI stopped working, NetworkManager can't find my RealTek RTL8822BE wireless card anymore. I used to have a lot of problems with this card in the past but Larry's github repo (https://github.com/lwfinger/rtw88) has been working for me for a long time. until today. Booting with an older kernel doesn't fix the problem.

    Following the sticky in this forum:
    Code:

    Correction: I am currently running kernel 5.17.5 but the update that broke it was to 5.17.7. Neither kernel works so the issue probably isn't there.

    I also forgot to include this (and I didn't see an edit button):

    Code:
    $ sudo lspci -v

    Hi
    You need to install NetworkManager-wifi as the package was split and this is a recommends. I suspect you have disabled recommends hence the issue. Also should be at 5.17.9 kernel on 20220521 snapshot.

    Thank you, installing NetworkManager-wifi solved the issue.

    I can't remember changing that setting but zypper was indeed configured to not install recommended packages, I've reverted that change now.

    Hi
    Maybe because of texlive recommends? It was due to the packaging split in NetworkManager...

    You can delete the broadcom-wl packages if there is no broadcom Wlan Chip.
    And set them to the Locklist.
