Bug 27843

can you post output of "lspcidrake -v"

in 5.10 series kernels there the in-tree rtw88 driver has gained support for 8821ce devices.


you could also try to remove any configured wireless device, and reboot back into 5.10 series kernel and try to re-configure the wireless.

does it work then ?

Re-configuring the wireless devices did not solve the problem.

ok so the new rtw88 kernel driver definately detects your hw.


is rtlwifi-firmware installed


Can you check if there are some references to the old driver in /etc ?

as root do:

grep -R rtl8821ce /etc

also please check dmesg or journal for any errors reported regarding rtw88

Canyou intstall it, reboot and try to reconfigure wireless

I cannot connect to the internet from Mageia at this moment, is there a way to download it to Windows and then move it to Mageia?

If you still have kernel 5.9 installed, you can boot with that kernel and access internet.

otherwise, download this:
http://ftp.free.fr/mirrors/mageia.org/distrib/cauldron/x86_64/media/nonfree/release/rtlwifi-firmware-20201118-1.mga8.nonfree.noarch.rpm

and save it on an usb.

then you can install it with urpmi (or doubleclicking on in should suggest installing it with the package manager)

Installing rtlwifi-firmware did not solve the problem, and upgrading the kernel version removes the driver from the system.

Hi, thanks reporting this.

Hi all,

Here, the same issue. I can't connect to wifi in Hp 250 G7 with Realtek RTL8821CE.

Greetings!

CC: (none) => joselp

In HP 250 G7 with Mageia 8 Beta 2.

The Wi-Fi works correctly if updating the Wi-Fi firmware before the Kernel.

The problem is back a few days after updating.

Closing this bug, the internet connection is good now.
