Ruling out that there’s a hard switch that disabled the radio (doesn’t seem like it since you’ve used it recently), try to reinstall the following packages and reboot:

pamac reinstall linux510 linux-firmware manjaro-firmware

dunno why it’s installing rtl8821ce driver again :frowning:

Your system is still configured to automatically invoke DKMS for that driver upon installation, upgrade, or re-installation of any kernel package.

For some reason, the removal script (from the GitHub instructions) didn’t work.

Try it manually,

sudo dkms remove (modulename) --all

If you want to check current configured ones:

dkms status

47

removed. dkms status showing none

48

What do you mean? What did you run?

dkms status

And its removal? (You need to use sudo to remove it)

51

done.

sudo dkms uninstall --no-depmod -m rtl8821ce -v 1.0.0.r128.gf93db73 --all

This is quite the adventure!

Can you force re-install linux510, linux-firmware, and manjaro-firmware, and then reboot? Hopefully it doesn’t try to rebuild the dkms module for the Realtek driver.

okay i’ll check it
