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.
