Hello everyone, if anyone had a problem witth 8821ce, here is what i did to make it working properly even with Hidden network (in Kali Linux last version):

git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
chmod +x dkms-install.sh 
chmod +x dkms-remove.sh
./dkms-remove.sh
./dkms-install.sh 

if the precedent commands does not work properly or they display errors: try these next ones in the same folder where you cloned the repository:

make all
make install
modprobe 8821ce

[Optional] to verify our module if it is working and added properly :

dkms status
modinfo 8821ce
