Maintainership

[tomaspinho]

As of 28th February 2019, I will no longer have access to a machine with the Wi-Fi chip supported by this module. Therefore, I will no longer be able to maintain this repository from a functionality perspective.

If you are able to continue development, please contact me.

Has anyone had the chance to try our Linux 5.12-rc2, especially with a RFE 2 chip? How is it looking?

Works fine for me with no speed issues. (I never had any speed issue.)

it's that really RFE2 chip?

See #26 (comment)

OK thanks. interestingly. Can you put a link with your dmesg here? I never had any speed issue before (with 8821ce driver).

[pawitp]

There's nothing else relevant in there.

A big fat thank you from me too! Your drivers are the only that worked for me (debian sid, kernel 5.10)! The package firmware-realtek didn't help me because of the RFE2 issue detailed here!

[alium]

hi, i tried kernel (linux-zen) 5.12.0. This kernel support now 8821ce RFE2 ... but as i wrote above, the driver is not enough good. Your driver is much better (no TX drop, better speed).

Yesterday i bought a new laptop with Ryzen3 for one small company and inside is coincidentally Rtw8821ce :-D So i tried 5.12 kernel... and.... no chance :D :D this newest Realtek 8821 contain now RFE4 !! and (of course) not supported by kernel... But which driver works out-of-box? rtl8821ce from @tomaspinho ! So we need your driver and your works! Thank you so much!!!

[tomaspinho]

So I guess I'm never getting rid of this 😅

@alium Realteks driver may also be causing crashes. Linux's 5,12 version of the driver added compatibilty for my laptops version of rtl8821ce, but it causes intermittent crashes

[crazyaccess]

Well it is still crashing in Linux Generic 5.15 from ubuntu / pop repositories,

I tried installing the offical rtl8821ce's driver package from pop repos -> not working | kernel panic I tried installing the tomas pinho's driver ( was working untill recently ) -> wifi driver doesn't show up.

I partially know that its due to Pop OS's mess in the kernel...

I mean TKG said so :

[crazyaccess]

It works perfectly on Arch Linux tho

You must add rtw88_8821ce built-in module to blacklist. https://github.com/tomaspinho/rtl8821ce#wi-fi-not-working-for-kernel--59

Well i did that already, the issue presists

( actually was doing it since the 510 kernel came out :sweat_smile: )
