Thread: wifi adapter Archer T4U now not connecting with post 4.12.14-lp151.28.36-default kernels

    Default wifi adapter Archer T4U now not connecting with post 4.12.14-lp151.28.36-default kernels

    I've discovered that since upgrading beyond kernel 4.12.14-lp151.28.36-default (so with both 4.12.14-lp151.28.40-default & 4.12.14-lp151.28.44-default) wifi connections have not been recognized in NetworkManager and will not connect. The connection works fine with 4.12.14-lp151.28.36-default.

    My system is Leap 15.1 and the device is model Archer T4U Version 3
    ID 2357:0115 (driver rtl8822bu).

    So, I'm back to using
    4.12.14-lp151.28.36-default until the issue is solved. I did try to see what the problem might be but it's beyond my tech skills.

    Have you put in a bug report? There was a bug report put in about 28.40 relating to another wi-fi controller and that was fixed in 28.44.

    Thanks for the suggestion. I was thinking that with some help I could explore further and narrow the problem down before making a bug report.

    Cheers

    There is no driver installed......

    The rtl8812au does not match to your device.
    Only rtl8822bu matches, but you have only the debug package installed.

    You can choose between these packages from these Repo:
    rtl8822bu-kmp-default or rtl8812AU_8821AU-kmp-default
    https://download.opensuse.org/reposi...Update/x86_64/

    I appreciate your help with this and I'm not sure what I'm doing wrong as I did uninstall rtl8822bu-debugsource and then each in turn installed first rtl8822bu-kmp-default and then rtl8812AU_8821AU-kmp-default and booted each time into the 28.44 kernel but nothing has changed - there's no wifi connection with either driver.

    I'm willing to explore this further with your guidance. Thanks.

    There is also a problem with wpa_supplicant, so if you use wicked, install the version from the OSS Repo:
    Code:
    zypper in -f wpa_supplicant-2.6-lp151.4.4
    If after reboot all is ok, lock the wpa_supplicant:
    Code:
    zypper al wpa_supplicant
