The 8821ce DKMS is pretty bad.
We need to wait for a few months until Realtek finished 8821ce support in rtw88.

Okay, thanks for sharing an update. Hopefully, things will improve by then.
I managed to work with the previous installation (update) temporarily. Any
alternative until then, Kai?

Do you mean the DKMS works on previous kernels?

Hi Kai,

Sharing/Forwarding a previous mail in response to - "Do you mean the DKMS
works on previous kernels?"

Apologise, since I am unsure. Hope this helps!
