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
