Wifi connection rt802.11ac

Hardware Support
1

If anyone knows how to get Zorin to run realtek 802.11ac wifi driver I’d love to know.

2

What is the controller product name for which you are looking for a driver?

3

From experience, I have noticed this technique works on Ubuntu 18.04 and Zorin 15.

4

Realtek RTL8821CA

5

Thanks, I’ve tried this solution several times, unfortunately for reasons I’m not able to fathom I cannot get the sequential lines of command entered with the usual method of shift+enter, or any other method, so I’m lost on getting this solution to work.

6

Or more accurately perhaps, 802.11AC/ABGN PCIE WLAN WITH BLUETOOTH 4.2 SINGLE-CHIP CONTROLLER

Can you please try the answer marked as the solution here and get back to us? https://askubuntu.com/questions/990378/wi-fi-not-working-on-lenovo-thinkpad-e570-realtek-rtl8821ce

PS - What part of Aravisian’s suggested link did not work? Try the commands one by one. Such as: first line sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r) and press Enter, then second line and press Enter, and so on.

Here’s the outcome of the first sudo apt entry:

blackoak@blackoak-Lenovo-IdeaPad-S145-14AST:~$ sudo apt-get install --reinstall git dkms build-essential linu-headers-$(uname -r)git clone https://github.com/tomaspinho/rtl8821ce

You have a typo in your command:
sudo apt-get install --reinstall git dkms build-essential linu-headers
Should say “linux”
sudo apt-get install --reinstall git dkms build-essential linux-headers

Oops.
Here’s the corrected result
blackoak@blackoak-Lenovo-IdeaPad-S145-14AST:~$ sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)git clone https://github.com/tomaspinho/rtl8821ce

In respect of Software Updater can you start then stop it by clicking on Cancel. Next go to Settings button of Software Updater and click it, then go to First Tab - if the sources of your updates are set to your country’s locale, change it to Main Server, then try again. :wink:

Gave that a go, no change. I’ll uninstall Zorin and try with a fresh download.
Thanks!

Ok. Re-installed and also found this solution for the realtek driver. Go to

Although the ask ubuntu site suggests another answer, (i.e the driver for rt802.11ac as a solution for the RTL8821CE which is what I’d been unable to find previously. I tried the one below and it worked sweet as. Used the sixth step and went from there.

[Realtek RTL8821CE chipset] and then use the answer in * [7. The rtw88 driver from lwfinger for the RTL8723DE, RTL8821CE, RTL8822BE and RTL8822CE chipsets]

Thanks all for your help.
