My laptop (Ollee L116HTN6SPW) has a Realtek 8821CE WiFi card.
Now at hirsute, this is "supported" in the linux-image-5.11.0-16-generic kernel,
and it works "well" for both WiFi and Bluetooth. However, this module (driver)
causes frequent freezes, randomly but usually within a few minutes of running
(thus very soon after boot): screen display remains frozen, no response to either
keyboard or mouse input. All I can do is to hold the power button to power off,
then reboot.
After reboot, I do not see any crash reports, nor logs about the freeze.
Please let me know if I should try to collect some info, and how.

For now I use the DKMS module/driver from /github. com/tomaspinho/ rtl8821ce
https:/
(having blacklisted rtw88_8821ce), and it seems to work perfectly.
