    Default AW: Realtek RTL8822BE device disconnected

    Btw, there are 2 OBS repositories building this project but they don't seem to be up2date.
    Since April 2019, nothing was change from Larry Finger in the git Repo, so it is an actual driver.

    You can also use:
    https://download.opensuse.org/reposi...leweed/x86_64/

    Uuuuu, this is even better (no kernel upgrades headaches). I was looking for rt8822be in OBS; I wasn't even sure if rtlwifi_new was the correct driver to build.

    Thank you all for the support!

    My software never has bugs. It just develops random features.

    Just an update to this thread: worked fine until the end of Nov. when no recompile and no reinstall of the rtlwifi modules made it work again.
    Based on the README file in the repo, the drivers for RTL8822BE are now on the rtw88 branch but for kernels > 5.2 it is recommended to use the default ones.

    I've tried to make install the modules from extended branch and from rtw88 branch but wireless was still not working. In the end I've removed the rtlwifi modules folder from kernel, removed the blacklist file, removed all packages installed from
    https://download.opensuse.org/reposi...USE_Tumbleweed repo or switched them to packman ones.
    After a reboot the onboard wireless card was back in business.

    Code:
    simona@devrog:~> inxi -N
    Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8168 
               Device-2: Realtek RTL8822BE 802.11a/b/g/n/ac WiFi adapter driver: rtw_pci

    OK,
    now for the normal user ....
    I use Suse SLED15 SP2, WIFI is not working, and the support told me,
    after guiding me one month incl. a fresh install, that my hardware is not supported.
    But he was so kind to give me the hint to this thread...

    The link to the driver from 10-Aug-2019, 23:49 is no longer working.
    I found a driver rtl8822befw.bin in the web.
    (Seems, that some linux distros have problems with this hardware)

    And there is the rpm-archiv in Sauerlands Post from 11-Aug-2019, 05:15
    It seems to be the easiest way (?)
    What should I do?
    Only installing the rpm?
    Which RPM? I have a rtl8822be, in the archiv is mentioned rtl8822bu-kmp-default......

    Must I do the blacklisting, as told here above?

    Greetings,
    Holger

    Please show:
    Code:
    /sbin/lspci -nnk | grep -iA3 net
    To see, which chip is inside.

    Also:
    Code:
    uname -a
    to see the running kernel.

    Its building in OBS, but you need the rtw88

    Code:
    modinfo rtw_8822be

    Use this kmp:
    https://download.opensuse.org/reposi...2.1.x86_64.rpm

    But secure boot has to be disabled in UEFI/Bios.
    And maybe you have to boot with kernel 5.3.18-22-2.1-default

    Thank you very much
    (Why am I using SLED ....?)

    Holger
    Download and install it, use Networkmanager to configure it (its easier as wicked/ifup)
    Maybe you have to switch to Networkmnager in Yast---System---Network-Configuration---global Options.

    Thank you very much, I will comply ...
    (I deleted the last post, because I had not seen your post before, my browser was a bit slow)
    Now I go on!
