Wifi rtl8821ce driver stopped working on Ubuntu 19.10
I was using ubuntu 19.10 and I had to install this Wi-Fi driver following instructions:
How to install Wi-Fi driver for Realtek RTL8821CE on Ubuntu 18.04?
However after an update applied and restart it just stopped working
I searched on additional drivers and this was disabled
I tried to re-enable it but nothing happened
How can I make them work back?
I had the same problem. I solved it by uninstalling the driver and installing the official Ubuntu package.
First, I uninstalled the old driver:
cd rtl8821ce/
sudo ./dkms-remove.sh
Then downloaded the driver to my phone: https://packages.ubuntu.com/eoan/all/rtl8821ce-dkms/download
Moved it via USB to my laptop.
Installed it with dpkg:
dpkg -i rtl8821ce-dkms_5.2.5.2.1.30816.20190425-0ubuntu1_all.deb
And finally rebooted the laptop.
