I just bought a Lenovo ideapad S130 141GM and installed Ubuntu Budgie 19.04. The wifi chip is a rtl8821ce so i had to install a driver with the commands :

sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r) git clone https://github.com/tomaspinho/rtl8821ce cd rtl8821ce chmod +x dkms-install.sh chmod +x dkms-remove.sh sudo ./dkms-install.sh

After rebooting, it worked, i could see many networks, but not my box. After that i used a wifi dongle with a RTL8188EUS which worked directly out of the box and saw the same networks and my box.

My box is working on channel 6, so it is not a problem of country channel allocation. The signal level o my box is of course much higher than the signal of all others networks and there is no other network on channel 6 (I tried on other channel without success too). My provider is "Free".

Does somebody have the same problem solved and could give me a hint of where to look (I would be happy to be able to use again the usb connector occupied by the wifi dongle) ?

Thanks in advance.

  • What is "but not my box"? Uninstall your current dkms driver and try this one... https://github.com/shubham151/rtl8821ce. (git clone https://github.com/shubham151/rtl8821ce.git). Don't follow the ReadMe there for how to install it, rather, follow the same procedure that you did before so that you get the dkms install. Start comments to me with @heynnema or I may miss them. Report back. – heynnema Nov 17 '19 at 16:19

  • @heinema Well there is a small problem : frank@frank-Lenovo-ideapad-S130-14IGM:~$ git clone github.com/shubham151/rtl8821ce.git fatal: le dépôt 'github.com/shubham151/rtl8821ce.git' n'existe pas – Frank Nov 17 '19 at 16:49
  • Correct command should be git clone https://github.com/shubham151/rtl8821ce.git – heynnema Nov 17 '19 at 17:14
  • What is your MTU set to in your network connection script? – heynnema Nov 17 '19 at 17:16
  • my box = wireless ADSL router – heynnema Nov 17 '19 at 17:18

From the comments...

Uninstall your current dkms driver (https://github.com/tomaspinho/rtl8821ce)...

cd rtl8821ce          # old source folder
sudo ./dkms-remove.sh # uninstall old dkms driver

And try this one... https://github.com/shubham151/rtl8821ce. (git clone https://github.com/shubham151/rtl8821ce.git). Don't follow the ReadMe there for how to install it, rather, follow the same procedure that you did before, so that you get the dkms install.

git clone https://github.com/shubham151/rtl8821ce.git # git clone new driver
cd rtl8821ce             # new source folder
chmod +x dkms-install.sh # make executable
chmod +x dkms-remove.sh  # make executable
sudo ./dkms-install.sh   # install new dkms driver

For ubuntu 20.04 this should do the trick:

apt install rtl8821ce-dkms
