I have an ASUS Vivobook model M712D, Ubuntu 20.04, kernel 5.13.0-37, Realtek rtl8821ce with 5.5.2.1 driver.
The wireless option in Settings disappears randomly after reboot. Rebooting does not fix the problem. If I boot into Windows 10 and then return to Ubuntu, it miraculously reappears. This gets to be tiresome. Any help would be appreciated.
