How can I set up the drivers for the RTL8821CE network adapter on Ubuntu 20.04?

So, I’ve been struggling a bit and could really use some help. I recently got my hands on a laptop with an RTL8821CE network adapter, and I decided to give Ubuntu 20.04 a shot. Everything was going smoothly at first—great interface, smooth installation, all that good stuff. But now I’m stuck and it’s driving me crazy!

The issue is that my Wi-Fi isn’t working at all. I thought I could simply connect to my Wi-Fi network and get started, but it seems like the drivers for my RTL8821CE adapter aren’t set up properly. When I go to the Wi-Fi settings, it just says “No Wi-Fi adapter found,” which is frustrating because I know the hardware is there. I’m pretty sure it has something to do with the drivers, since I read that many users have had similar issues with this adapter on Ubuntu.

I’ve tried a few things already—like checking the additional drivers section, but nothing seems to show up there for my network adapter. I even attempted some terminal commands that I found in forums, but I’m not the most command-line savvy person, and I think I might have messed something up. Plus, each time I reboot, it seems like I have to go through some of the same steps again.

I came across a GitHub repository that mentioned some steps for installation, but I’m a little intimidated by the whole build and install process. Should I be following these steps? Is there an easier way to get the drivers working?

If anyone out there has successfully set up their RTL8821CE on Ubuntu 20.04, I’d really appreciate a step-by-step walkthrough. A few tips on what commands to enter in the terminal would be super helpful, or maybe some links to resources that break it down for beginners? I’m just eager to get my Wi-Fi up and running so I can dive into all the cool stuff with Ubuntu. Thanks in advance for your help!

    1. To resolve your Wi-Fi issue with the RTL8821CE network adapter on Ubuntu 20.04, you’ll need to install the proper drivers. Since the drivers aren’t included by default, you can utilize a GitHub repository that contains the necessary driver for your specific adapter. First, open your terminal (you can do this by pressing `Ctrl + Alt + T`) and install the necessary packages by executing the following command:

      sudo apt update && sudo apt install build-essential dkms git

      Next, clone the repository with the following command:

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

      Change into the cloned directory and install the driver using these commands:

      cd rtl8821ce
sudo ./dkms-install.sh

      After running the installation script, reboot your laptop. Upon reboot, your RTL8821CE wireless adapter should be recognized, and you should see available Wi-Fi networks in your settings. If you encounter any problems during installation, consult the repository’s README file for troubleshooting hints and further assistance.

      Getting Your RTL8821CE Working on Ubuntu 20.04

      Sounds like you’re really struggling with that Wi-Fi issue! The RTL8821CE is known for having some driver problems on Ubuntu, but no worries, we can try to sort this out step-by-step.

      Step 1: Check if the Driver is Installed

      First, let’s see if the driver is even installed. Open your terminal (you can do this by pressing Ctrl + Alt + T) and run this command:

      lspci -nnk | grep -A3 -i net

      This should list your network devices. If you see your RTL8821CE adapter but no driver listed, we definitely need to install the right driver.

      Step 2: Install Required Packages

      Before we go to GitHub, let’s install some packages that will help us build the driver. Run the following commands one by one:

      sudo apt update
      sudo apt install build-essential dkms git

      This installs necessary tools for building drivers from source.

      Step 3: Clone the Driver Repository

      Now, we need to get the driver from GitHub. In the terminal, run:

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

      This will download the necessary driver files to your laptop.

      Step 4: Build and Install the Driver

      Now we need to install the drivers. Navigate into the directory you just created by running:

      cd rtl8821ce

      Then, run these commands:

      sudo ./dkms-install.sh

      This will build and install the driver for you. You should see some output in the terminal.

      Step 5: Reboot

      Once installation is done, restart your computer:

      sudo reboot

      Step 6: Check if Wi-Fi Works!

      After rebooting, check your Wi-Fi again. Hopefully, you can see your available networks now!

      Troubleshooting

      If it still doesn’t work, you might need to ensure that secure boot is disabled in your BIOS/UEFI settings. Sometimes, that can block the drivers from loading correctly.
