That file is installed on my system, yet I get the above error messages. $ ls -l /lib/firmware/rtw88/rtw8821c_fw.bin -rw-r--r-- 1 root root 139472 Dec 16 17:54 /lib/firmware/rtw88/rtw8821c_fw.bin $ sha1sum /lib/firmware/rtw88/rtw8821c_fw.bin 69c087a1963953c2e0e8a8338237e0689b4d7c40 /lib/firmware/rtw88/rtw8821c_fw.bin So something else must be broken.
