Description Sérgio M Basto 2020-12-18 23:16:34 UTC

As reported in several places and by several we still need use rtl8821ce code from https://github.com/tomaspinho/rtl8821ce/ to make wifi working 



https://forum.manjaro.org/t/rtl8821ce-wireless-adapter-not-working/38014/4 
https://github.com/tomaspinho/rtl8821ce/issues/176

rtw88_8821ce doesn't work [1]  can't connect  [2] , I also see this [3]
Firmware seems it loads well .

Comment 1 Flavio Grossi 2020-12-23 09:45:22 UTC

I can confirm the issue with the following hardware from a lenovo BGCN24WW

Same issue here, RFE4 is not supported, laptop Asus M509DA:

I use the old driver as I need the wifi, no lan port.

Comment 8 xrootware 2021-03-07 20:20:46 UTC

Have some problems with built-in kernel driver and adapter 8821ce on lenovo laptop. Kernel 5.11. Random disconnects. BTW https://github.com/tomaspinho/rtl8821ce/ works fine.

Comment 9 Flavio Grossi 2021-04-14 07:22:30 UTC

it seems to have been fixed (at least for my model) with recent kernels.

I'm on 5.11.12 right now (on fedora). Will report back if i have any issues with stability or anything else.

Comment 10 Sérgio M Basto 2021-04-14 09:58:00 UTC

That is a good new , I will try kernel 5.11.12 (on fedora) as well .

For users that doesn't use Fedora, attention Fedora kernel may have backports from 5.12 kernel ... ( I haven't time to check where is the fix on vanilla kernel )

Comment 11 Flavio Grossi 2021-05-04 10:17:22 UTC

little update: this seems to work fine, but i repeatedly (every 5 minutes at least) have this in dmesg:

anyone seeing something similar? Has it already been reported?

Comment 12 Sérgio M Basto 2021-05-04 10:29:43 UTC

After upgrade to F33, I also see this message: 
Apr 24 14:53:28 ideapad.local kernel: ------------[ cut here ]------------
Apr 24 14:53:28 ideapad.local kernel: purge skb(s) not reported by firmware

Thanks for the report

Comment 13 Flavio Grossi 2021-06-27 17:07:50 UTC

Unfortunately with the 5.12 kernels it seems to provoke an hard freeze of the operating system after a few minutes.

Switching back to a 5.11 kernel seems ok.

Anyone has the same problem? Cannot even produce a useful log because no traces of the crash survive the freeze (but i heavily suspect the wireless driver is the culprit here)

Comment 14 Sérgio M Basto 2021-07-01 22:39:46 UTC

seems that works for me without ooops messages with kernel 5.12.12-200.fc33.x86_64

Comment 15 Flavio Grossi 2021-07-02 07:27:17 UTC

It's weird but it was unusable for me on 5.12 kernels, it would cause an hard freeze within minutes of use

However, adding

options rtw88_pci disable_aspm=1

when loading the kernel module seems to have fixed it for me on 5.12 kernel (and it got rid of the kernel traces on the 5.11 one)

Hope this helps anyone

I resolved this by replacing the rtl8821ce with OEM Asus Atheros QCA9377.
