RTL8821CE doesn't connect to WIFI

Hi everyone!
So as the title says WIFI doesn’t work. I did the following instructions but it didn’t work for me:

sudo pacman -Syyu

sudo pacman -S dkms linux59-headers

(59 since my kernel version output of uname -r is 5.9.16-1-MANJARO)

pamac build rtl8821ce-dkms-git

I tried many things and none worked, when I do lspci it shows my network adapter so I doubt its a hardware problem since it worked with Windows (the OS i had hours ago).

Result of journalctl -b | grep 8821ce:

Thanks!

Kernel is EOL … pls update to “LTS-Kernel 5.4 or 5.10” or Kernel 5.11 ?!

i think … change Kernel to 5.10, rebuild rtl8821ce-dkms-git again and you have fun :wink:
