<SOLVED>: Wifi gone after upgrade

[Nils0101]

Hello everyone,
I just updated to Linux Mint 19.3 Cinnamon from 19.2 - everything was fine right after the update. The wifi was working.
Right after I was asked to check my drivers (see screen shot) - after choosing either one the wifi is gone.
Looking at my network - there is no wifi at all.

Translation of pic: this computer uses an alternative driver // at the bottom don't use

Every hint would be a great help.
Thanks
Nils

[sleeper12]

Can you reinstall the driver in Driver Manager, uncheck the box, then check it again?

[Nils0101]

i did that before and nothing happened

[sleeper12]

Try:

Code: Select all

 sudo apt install --reinstall rtl8821ce-dkms 

Reboot

[Nils0101]

seems like nothing changed

[sleeper12]

Let's see:

Code: Select all

reboot?

[sleeper12]

reboot?

No need. It seems like you have no driver or it's just not showing, but I'm not sure why. Are you dual booting with Windows?

[Nils0101]

nope

[Nils0101]

should i wun this to install?

sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh

[sleeper12]

Yes, you can try that & reboot after.

[Nils0101]

still no good

[sleeper12]

See if this makes any difference:

Code: Select all

 sudo apt autoremove 

[Nils0101]

not that I could see

[sleeper12]

Maybe restart your router & machine.

[Nils0101]

[Nils0101]
