What I've tried:

How to install Wi-Fi driver for Realtek RTL8821CE on Ubuntu 18.04?

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiv9P-j9a_4AhV1R2wGHRfSAu8QFnoECAkQAQ&url=https%3A%2F%2Fwww.geeksforgeeks.org%2Finstalling-realtek-rtl8821ce-driver-to-use-the-wireless-network-interface-in-ubuntu%2F&usg=AOvVaw2KZvMj-eakKJ60i6-3euG8

there seems to be a network adapter on the official ubuntu website: https://ubuntu.com/certified/component/753

but I don't know how to install this network adapter. I'm currently asking this using usb tethering with mobile data.

Any help will be greatly appreciated. Thank you!

I had a similar issue. After updating linux firmware, reinstalling Linux, Windows I finally discover that there are two factors which cause it:

  1. Windows Hibernate
  2. Windows fast startup

With Windows fast startup turned off and Windows shutdowned (not hibernated, sleeped etc.) I have Wifi on Linux. Windows has to block the wifi adapter when not shut down completely.

I hope this will help you get it running !

If you can connect using an ethernet cable or some other method, you can share wifi using the bluetooth of your cellular device, try running the command

sudo apt install rtl8821ce-dkms --reinstall

This worked for me on my Hp 14s laptop. Hope this helps!
