RTL8821CE driver malfunctioning
Solution 1:
From the comments...
Uninstall your current dkms driver (https://github.com/tomaspinho/rtl8821ce)...
cd rtl8821ce # old source folder
sudo ./dkms-remove.sh # uninstall old dkms driver
And try this one... https://github.com/shubham151/rtl8821ce. (git clone https://github.com/shubham151/rtl8821ce.git). Don't follow the ReadMe there for how to install it, rather, follow the same procedure that you did before, so that you get the dkms install.
git clone https://github.com/shubham151/rtl8821ce.git # git clone new driver
cd rtl8821ce # new source folder
chmod +x dkms-install.sh # make executable
chmod +x dkms-remove.sh # make executable
sudo ./dkms-install.sh # install new dkms driver
