Wifi on Pop!_OS 22.04

Ryebread095 · April 25, 2022, 10:01pm

I decided to update to Pop!_OS 22.04 today and found that WiFi no longer worked despite being on a kernel that should have the drivers, 5.16.19. The Intel AX210 card was working previously on Pop!_OS 21.10 and in Windows, and I didn’t have an issue with my Bluetooth mouse. However, after the update, Pop thought there was no WiFi adapter.

The solution I came to was to install the backport Intel WiFi driver package:

sudo apt install backport-iwlwifi-dkms

After a reboot, my WiFi was working again.

I have upgraded from Pop!_OS 21.10 to 22.04 this morning, and I have experienced no issues with wifi.

I did not have the need to install the backport-iwlwifi-dkms package.

I had this issue with a fresh install of Pop!_OS 22.04 on my laptop that arrived yesterday - Ended up having to load the ax210 drivers from Intel’s site and manually copy them into /lib/firmware as I didn’t have a USB-ethernet converter…

I just upgraded a few minutes ago, no wifi issues, but some apps that weren’t blurry before are blurry, like Firefox.

Travis, are you using scaling and Wayland? If so, you’ll need to set an environment variable to tell Mozilla apps to run in Wayland instead of X11.

I was able to use this article from the Arch Wiki to fix Firefox and Thunderbird on Wayland

That was it, I needed to add export MOZ_ENABLE_WAYLAND=1 to my ~/.profile thanks!

Thanks @niwarren, this just worked for me. To save some time to future users, these are the specifics:

Using a device connected to the network download the files iwlwifi-ty-a0-gf-a0.pnvm and iwlwifi-ty-a0-gf-a0-71.ucode (presumably, versions later than 71 will also work, when they appear, check the parent URL to see if there are newer versions).
Copy those files to e.g. a USB stick
Logged in in your Framework, copy the two files from the USB stick in /lib/firmware/. You will need administrator rights (sudo), e.g. run sudo cp /media/<your_username>/<your_usb_device's_name>/<filename> /lib/firmware.

The wireless interface worked for me after a hard reset.

Hey, I’m in the same situation and have tried all of the above mentioned solutions and a few besides, and none proved effective. Checking the system logs, I see:

any ideas how to interpret these errors?

Micah_McClimans · May 7, 2022, 8:15am

Ok, it seems that both removing the latest firmware microcode file from /lib/firmware and uninstalling backport-iwlwifi-dkms seems to have fixed it for me.

I’m having intermittent WiFi issues, would this be a proper fix or is this something else?
