Lenovo 130 15ast - 18.04 - RTL8821ce

Question

I'm very new to Linux and this community. The computer is a gift to a friend who will only use Ubuntu and needs wifi.

I bought the Lenovo. Installed an SSD. Downloaded 18.02 and installed.

There is no wireless showing on the main screen. Ethernet is okay.

I found two articles here which had text to paste into Terminal. These ran apparently without error. Both predicted that wireless would appear after a reboot but it doesn't for me.

I notice that airplane mode can't be found in Activities. Working F5 (airplane symbol) does nothing.

I tried other text (lsm?) in Terminal which supposedly looks for installed drivers. In the long list is a Realtek network block of info. It has some text saying "unclaimed."

I read that I must be sure that secure boot in BIOS must be disabled. I don't find that in the BIOS but I've set things to l egacy boot before running terminal input above.

Much of the discussion I read here is beyond me.

Here is what I ran and results:

From: Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE)

I ran:

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

The result was:

I rebooted and found no indication of a wireless device.

From: How can I list installed network cards using Terminal?

I ran:

I rebooted and there was no sign of a wireless device

from another source, I entered

You might want to check your text - Ubuntu releases are yy.mm in format (with exception being speciality releases like Ubuntu Core 18), and there was no 2018-February release? or was the 18.02 a version for something else? in which case please clarify Also providing the links to what you followed, or at least the commands you tried & results would be useful instead of vague "found articles .. pasted into terminal.." - what articles? what commands & what output did you get (eg. what was around the 'unclaimed' ...)? — guiverc, Commented Apr 28, 2019 at 5:09
Good news, support for the rtl8221ce has been posted to the mainline kernel, not sure when it will eventually appear for us, but tomaspinho comments below, the reference. — X Tian, Commented May 29, 2020 at 13:24

I had to install a driver, following the steps here to find guides for multiple different chip sets.

In the here discussed case RTL8821CE:

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

Secure Boot has nothing to do with it. We would, however require some extra information from you to help you.

Please update the post with more information (output of lsusb , dmesg , uname -a) and we might be able to help only then.

Otherwise, the ppa at rtl8821ce has what you want. Follow the steps there. Ask questions here if you get stuck.

Please follow the instructions on that site for Lenovo Laptops:

sudo modprobe -r ideapad_laptop

To permanently blacklist:

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"

I have the same issue and tried to follow your steps, but it did not seem to work, leaving me with No Wi-Fi Adapter found.

@mrk Are you sure you had the same issue? Can you provide the output of lshw -c network and dmesg (preferably on pastebin).

So I am not quite sure whether I had the same problem - installing the driver did it for me. I added more detail in an answer bellow. Thanks for the response.
