    Yes, I appreciate that, hence my additional comment in post #9

    ... but you can download the src.rpm and build them by your own. I think you have to patch it for Leap 15.4.......
    I'll have to investigate that possibility, not yet had the need to build any software.

    Thanks.

    Confusion or misunderstanding on my part I feel.

    So... I've again installed "rtw88-kmp-default" (git20210919_k5.3.18_59.19-lp153.2.3) and removed both "rtl8821ce-kmp-default" and "rtl8821ce-blacklist-rtw_8821ce"

    However that seems to have be a retrograde step as after a reboot I had no wi-fi ( https://paste.opensuse.org/view/raw/270f65dc )

    The journal shows:
    Code:
    paul@HP255G7:~> journalctl -b | grep -i rtw_8821

    Remove "rtw88-kmp-default" and again install both "rtl8821ce-kmp-default" and "rtl8821ce-blacklist-rtw_8821ce", reboot and wi-fi is back working...

    Hmm... Just noticed also it didn't match the kernel 5.3.18-59.24.1 Maybe a partially updated mirror(?) I've just refreshed you repository and now am offered rtw-88 git20210924_k5.3.18_59.24-lp153.6.1

    I'll give that a try, but I won't be able to do that now until this evening.

    Thanks.

    This was a switch from rtl8821ce to rtw88 only over ssh and reboot, as you can see, now it is using rtw88.

    PS
    OBS was the problem, has build but not delivered to the Repo.........

    Default Re: c and wifi = problem

    Found time to look at this before this evening.


    I guess this is the changelog entry you referred to:

    * rtw88: 8821c: correct 2.4G tx power for type 2/4 NIC
    NIC card saves calibrated TX power index in the efuse(ROM).
    Driver loads TX power idex when interface is up.
    The problem is type2/4 NICs loads 2.4G TX power index
    from wrong position. This patch corrects the offsets.
    So, driver loads real 2.4G TX power index for type 2/4 NICs.
    2.4G performance increased when using correct TX power index.
    The link I have is on 5G so that would not be relevant.

    Reinstalling (this time the correct one) rtw88 and wi-fi is available, but at a significantly reduced bit rate as compared with that provided by rtl8821ce, as I outlined in post #8 . Also a scan only reveals 3 available access points, as opposed to (typically) 10-11 when using rtl8821ce.

    Also there are some errors in the journal, as shown:


    Code:

    I don't know if some of those (first two and the last) warrant a bug report, and if they do, where to report?


    Again, for the moment I'm reverting back to the rtl8821ce.


    Thanks.

    Default AW: c and wifi = problem

    This is the driver from kernel, you can ignore. That was the bug I mentioned and the kernel-developer said: Its an Realtek problem, they have to patch. What Realtek has done in Kernel 5.11 or 5.12.
    So after Kernel 5.12 you do not need any seperate kmp.
    Code:
    Sep 24 13:16:55 HP255G7 kernel: rtw88_8821ce: disagrees about version of symbol rtw8821c_hw_spec
    Sep 24 13:16:55 HP255G7 kernel: rtw88_8821ce: Unknown symbol rtw8821c_hw_spec (err -22)

    Code:
    Sep 24 14:14:18 laptop kernel: rtw_8821ce 0000:02:00.0: failed to get tx report from firmware
    I do not know.....

    But its working.

    Start bug reporting with openSUSE.

    https://www.realtek.com/en/products/...item/rtl8821ce

    Wifi adapter has 1 antenna?
    With USB 2.0 connection you cannot get more than ~280 Mbit/s. Maybe new driver knows about this.

    Two I believe, but I've no intention of opening up this laptop to confirm...

    It's not USB, and using the rtl8821ce driver I consistently and reliably get a link speed of 434Mbit/s between laptop and router.
