Lenovo L15 - no wlan found

[miodas007]

I have problem with WIFI on Lenovo L15 (on Windows everything works fine). Device detected on the windows is Realtek RTL8852AE WiFi 6 802.11ax PCIe

I have the newest BIOS:

sudo dmidecode -s bios-version
R19ET35W (1.19 )

Your device uses the driver rtw89pci. Let’s build it. From the terminal:


sudo apt update
sudo apt install build-essential git
git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make install
sudo mkdir /usr/lib/firmware/rtw89
cp rtw8852a_fw.bin /usr/lib/firmware/rtw89
sudo modprobe rtw89pci

Your wireless should now be working.

After each kernel version update, you must rebuild:


cd ~/rtw89
make clean
git pull
make
sudo make install
sud modprobe rtw89pci

Please retain the files and these instructions for that time.

[miodas007]

sudo mkdir /usr/lib/firmware/rtw89
cp rtw8852a_fw.bin /usr/lib/firmware/rtw89

I had rtw8852a_fw.bin file under rtw89 directory previously - and I when t tried :


sudo modprobe rtw89pci
I've got:


modprobe: FATAL: Module rtw89pci not found.


But following by your advice I build it from this repo, overwrite driver and modprobe works fine !! Thanks.

I build it from this repo, overwrite driver and modprobe works fine !! Awesome! Glad it's working as expected.

Please use thread tools at the top to mark Solved. The searchers will appreciate it.

Hello, I'm having the same problem on my Lenovo Legion 7 with the same wifi card. I tried all the steps and I get an error on the last step: "sudo modprobe rtw89pci." The error reads:


modprobe: ERROR: could not insert 'rtw89pci': Operation not permitted

Can you help me resolve this? Thank you!

Edit: Nevermind problem solved when i disabled SecureBoot in bios. No more error message and now wifi works!! Thank you!!!

Any suggestions?

[chili555]

cp: cannot stat 'rtl8852au*.bin': No such file or directory
make: *** [Makefile:61: install] Error 1I assume this is a freshly cloned version of the driver; that is, in the last few weeks.

What, exactly do you have for firmware in the folder?


ls ~/Documents/rtw89 | grep bin

I have:


rtl8852au_config.bin
rtl8852au_fw.bin
rtw8852a_fw.bin
If you do not have those, try to refresh the driver file:


cd ~/Documents/rtw89
git pull
ls | grep bin

Now do you have the firmware files? If so, try again:


make clean
make
sudo make install

Reboot.
