Follow The Steps Below to fix wifi adapter issue in Linux Mint:



1. Turn on the laptop and connect it to the internet via LAN wired connection.

You can see how to do all the steps it in this video:


Then restart the system, and If Linux Mint still does not recognize your wifi move to step 2:


2. Turn on the laptop and connect it to the internet via LAN wired connection.

2.1  Open terminal either via Ctrl+Alt+T shortcut key or by searching for ‘terminal’ from software launcher.

2.2 type the following command command, in this order, one after the other finish:

sudo apt remove rtl8821ce-dkms
sudo apt install git
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh 


Then restart the system.


If this does not work either, we will need to go the long way, step 3:

Make sure to remove the driver if you have previously unsuccessfully installed it via sudo ./dkms-install.sh and then the directory rm -rf rtl8821ce. It may be located in cd /var/lib/dkms/, delete it there too.


3. Disabled secure boot (you need to reboot after this command and enter the password chars on the blue screen):

sudo mokutil --disable-validation

3.1 Upgraded the Kernel from 4.15 to 4.18, cuz for some reason it wouldn't work with 4.15. Use uname -a to check your kernel version.

sudo apt install linux-generic-hwe-18.04 sudo apt update && sudo apt upgrade -y

3.2 Then reinstalled the dkms headers:

sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)

3.3 Pulled the github respiratory:

git clone https://github.com/tomaspinho/rtl8821ce

3.4 Entered the new directory:

cd rtl8821ce

3.5 Changed the the file permissions:

chmod +x dkms-install.sh chmod +x dkms-remove.sh

3.6 Synced the driver to the correct kernel version:

make sudo make install

3.7 Installed the driver:

sudo ./dkms-install.sh

Finally, reboot.
