Intel Wireless card AX1675 Ubuntu 20.04 No Wi-Fi Adapter Found

Thanks but it does not work, it can even boot, the screen freeze in computer brand moment.

Ok, lets try the backports on a working kernel

sudo apt install build-esssential
wget https://cdn.kernel.org/pub/linux/kernel/projects/backports/stable/v5.14.13/backports-5.14.13-1.tar.xz
tar -xvf backports-5.14.13-1.tar.xz
cd backports-5.14.13-1
make defconfig-wifi
make
sudo make install
make clean

You will likely see some errors but it should complete, reboot and test

Two of the same errors in the same day? https://askubuntu.com/q/1376871/
Try

sudo apt install flex

Then try the make defconfig-wifi again

Nothing changed. The error is the same, and WIFI is still not working.

I am curious that distro and kernel both have LTS, will Ubuntu 20.04 provide new handware support in furture update like kernel?

[jamesyuan]

BTW, I tried 'sudo apt-get install --install-recommends linux-generic-hwe-20.04-edge', actually 5.13 kernel is installed, I see some errors during the installation (e.g. error asscoaiting to 460 gpu driver) and I found that the laptop can not be booted (will be forwarded to initramfs interface )

[jeremy31]

Are you sure the error was the same or did it say command yacc not found?
You might have to

sudo apt install bison byacc
make clean
make defconfig-wifi

and see if it makes it through, it should say changes written to .config on the last line if it works

Hi,

Yes, this time works fine, the build takes 2-3 mins. After reboot, I can see the WIFI logo, however, the system is super slow now, it takes 2 mins to open settings, and it always shows looking for visible networks (nothing found). Meanwhile, something strange happend, for example, can't shut down (black screen with cursor), vscode can't be opened.

Lets se what this shows
