I bought a new Lenovo Ideapad 5 without any OS. I installed Ubuntu 20.04 on it. However, in Settings -> Wi-Fi I see "No Wi-Fi Adapter Found". I already spent hours trying to solve this problem. I don't know, what I'm missing.

Here, I paste the output from some common commands I found.

sudo lshw -C network

Also, in Software & Updates -> Additional Drivers there is "No additional drivers available"

I have no idea, what to do next. Please, help.

  • Check secure boot in bios. Is it off?

  • Secure boot was enabled. I just changed it to disabled. Should anything be changed now? Commented Jul 19, 2021 at 7:08

    If it isn't up yet, that would be your best bet... or you could try to upgrade kernel.

    Try hard reboot once more. If that doesn't work, ensure that you hit save changes before leaving. Ive made that mistake before.

To get the realtek 8852 PCI adapter working with Ubuntu, follow these steps:

  1. Download dependencies:

     sudo apt-get update
     sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git
  2. Install 'fix':

    git clone https://github.com/lwfinger/rtw89.git
    cd rtw89 && make && sudo make install
  3. load module:

    sudo modprobe rtw89pci

    If you are lucky, this is all you will need to do. The driver should be loaded. If not, you will likely know. The driver load attempt will have caused an error. If this is the case, click the source link below for details.

  • Thank you. I installed Ubuntu today, so I'm not losing anything. I'll try to install this again with disabled Secure Boot and I hope this will solve my problems Commented Jul 19, 2021 at 8:11
  • I know it will. It is a common issue. Secure boot looks for windows signature to decide if an app is secure. Other distros such as RHEL have gone as far as to dupe the software signatures. Ubuntu just provides you with the info to do it yourself if needed. The easier option is just to say good riddance.

    So I disabled Secure Boot and installed Ubuntu again. I still have the same problems. Basically, nothing changed from the previous output Commented Jul 19, 2021 at 8:53
  • @NateT I believe OP will require firmware.

    Thanks. This helped me, it did the job. I installed Ubuntu 22.04.3 on a Lenovo Thinkpad G4
