1 year ago Hi, I had got the same error. Then I used this driver https://github.com/morrownr/8821cu-20210916 to replace the old one, and the network recoverd.
Can confirm, this one compiles without errors and works afterwards.
But I have one additional question, someone may know to fix.
Very often my WiFi won't work anymore, when I reboot after an update/upgrade my Ubuntu 22.04 LTS by:
sudo apt update & sudo apt upgrade
Then the WiFi-Adapter won't work anymore until I completely recompile "reinstall" it (only uninstall and install without recompiling won't work).
I wrote some automated script to do that for me, so that I don't have to input the commands all the time by hand:
#!/bin/bash
# Change into sourcecode directory
#cd ~/Downloads/rtl8821cu/ # Previous repo (not working currently)
cd ~/Downloads/8821cu-20210916 # Current working repo
# Grab changes if there are some
git pull
sudo make clean
sudo make
sudo make uninstall
sudo make install
#---------------
#Edit: Optional Modprobe
#sudo modprobe 8821cu
#---------------But that is soooo annoying, because I need to wait that the driver got recompiled and reinstalled -_-. So, has anyone the same problem and know how to avoid that behaviour?
Kind regards, Deph

And maybe add another command to make it work
sudo modprobe 8821cu@Dephrilibrium's steps worked for me
And maybe add another command to make it work
sudo modprobe 8821cu
Thanks for the hint. Personally I use the auto modeswitch described by the author in the repositories README.md, but I will add it in a second.
Kind regards, Deph

Unfortunately, it not works for me. Until a definitive solution shows up, I will keep the kernel 5.17.15 as default in my Ubuntu 22.04.

rtw_phydm_set_rrsr(adapter, temp_rrsr, FALSE);Heyho everyone,
yesterday I've made an update/upgrade of my ubuntu 22.04 LTS. Thereby, the latest kernel (6.2.0-26-generic) was installed, and my dongle showed no WiFi anymore in the taskbar network-window.
After playing around and a lot of restarts and recompile-tries, I came up with the idea, that linux is may confused by the different drivers, still stored within the different kernel-version folders in /lib/modules/ (see Makefile: MODDESTDIR := /lib/modules/$(KVER)/kernel/drivers/net/wireless/).
Therefore I decided to delete all my older kernel version folders (sudo rm -r 5*), restarted the PC and recompiled with my script above https://github.com/brektrou/rtl8821CU/issues/206#issuecomment-1435713760. One restart later, everything worked well again.
Hope that helps, if some is struggling with the same problem.
