Network controller driver of RTL8852ce does not work on 20.04

Question

Wifi is not available on my new Ubuntu 20.04 (kernel 5.15.0-76). I think it should be problems with network drivers.

I follow the step of https://github.com/juanro49/rtl88x2ce-dkms but it doesn't work after reboot. I wonder if there is a specified driver for Realtek 8852CE.

Was this problem there in the previous OS? Please mention what you hade previously. — Rishon_JR, Jul 02 '23 at 12:49
It is the first time I install Ubuntu on this laptop and this problem occurs. — Topsail, Jul 02 '23 at 13:14
Please edit your question to show the result of the terminal command: lspci -nnk | grep 0280 -A3 Probable correct driver: https://github.com/lwfinger/rtw89 Welcome to Ask Ubuntu. — chili555, Jul 02 '23 at 13:40
I have searched for the error and I have, so far, seen that it's harmless and may be resolved by updating the BIOS. — chili555, Jul 02 '23 at 19:42

First, please remove the ineffective driver:

sudo dkms remove rtl88x2ce/35403 --all

Next, install the correct driver:

sudo apt install --reinstall git bc
git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make install

You will probably need to disable Secure Boot. Reboot.

When your kernel version changes, then you need to do the following:

cd ~/rtw89
git pull
make clean
make
sudo make install

EDIT: Let’s load the required firmware:

cd /usr/lib/firmware/
sudo mkdir rtw89
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtw89/rtw8852c_fw.bin

Reboot.

Thank you for your help. However, the problem is still not solved after installation and reboot. Could you please offer more information on installing rtw89? – Topsail Jul 03 '23 at 06:02

Are there any clues in the message log? sudo dmesg | grep rtw – chili555 Jul 03 '23 at 12:28
Oh, an error occurs when loading this driver. I have updated the output. – Topsail Jul 03 '23 at 12:34
Please see my edit above in a few moments. – chili555 Jul 03 '23 at 12:47
Thanks! Though the problem is still not solved, there are some changes in dmesg. it seems that we are almost there. I will update the output. – Topsail Jul 03 '23 at 13:14
I am amending my edit. Please remove the file with the apparent invalid header length and try the edit again. I have changed the download location. sudo rm -r /usr/lib/firmware/rtw89 – chili555 Jul 03 '23 at 13:28
The problem has been solved with this file in your suggestion. Thank you very much! :-D – Topsail Jul 03 '23 at 13:40
BTW, I wonder what you think about the reason leading to this problem on 8852ce, sincerely. – Topsail Jul 03 '23 at 13:42
I think the issue is that you installed an older Ubuntu version, 20.04, when the device is very new. The required driver and firmware are already included in, for example, 23.04. I'm glad it's working. – chili555 Jul 03 '23 at 14:59

Network controller driver of RTL8852ce does not work on 20.04
