You have to cold reboot your laptop to enable Wi-Fi again. It is a known issue with the RTL8821CE driver.

  • power off
  • wait 1 minute
  • power on again and boot in linux

If you want to upgrade to kernel 5.9 at some point you will have to blacklist the integrated rtw88_8821ce driver first as it is not compatible yet with your adapter.

thanks for the help, it didn’t work for me, but the solution from @j8a works just fine!

thanks a lot, it works fine now, I’m new on manjaro and its good to see a good forum like this

Thanks :slight_smile:

I assumed that you had the driver already installed.

Nevertheless, keep the blacklisting in mind when you decide to move to kernel 5.9 or you will end up without Wi-Fi.
