@maxroby, from the line in dkms.5.11.0-11-generic:

  rtl8821ce, v5.5.2_34066.20200325, 5.11.0-11-generic, x86_64: installed

It means you're still running your 5.11 kernel with rtl8821ce-dkms compiled and installed. The same thing can also be found in the dmesg log. Is there anything wrong with the purge?

rtl8821ce has already in-tree kernel support, and it's named rtw88_foooo, e.g. rtw88_8821ce. So you need to uninstall that DKMS to try that in mainline kernel. I think your card, PCIID [10ec:c821] subsystem [17aa:c024], should have been supported.
