Wifi disappears after update

[batello]

Hello, I'm having a problem with my wifi: Anytime there is an update it disappears.
I connected my computer through USB Tethering, i purged my network manager and installed it back.
Usually it works but not this time.
I also checked Software and Updates to see whether I have drivers installed and it looks so
Using DKMS source for Realtek 8821C PCIe Wi-Fi driver from rtl8821ce-dkms (open source)

I don't have any more clues.
Can anyone help me?
Thank you.
