The first upgrade to 5.11 (1616168001) worked fine. Both Wifi and BT of the intel ax210 worked. The second version of 5.11 (1617215757) came with linux-firmware that broke the Wifi (BT still works fine).

This is the output of dmesg | grep iwlwifi

This is the exam same issue reported in here ([arch link)[https://bugs.archlinux.org/task/70071]).

I am currently trying to revert to the previous firmware version. I will report back.

I will try asap.

For the moment I can say that I tried 20210315 and 20210208 from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git.

The former (newer) causes the issue above, the latter (older) fixes it.

I will try the workaround suggested now.

The workaround works. Using the pop provided linux-firmware package and removing iwlwifi-ty-a0-gf-a0.pnvm restores the wifi.

Thank you.

For what it's worth, this is the output of lspci

03:00.0 Network controller: Intel Corporation Device 2725 (rev 1a)

I think the mainline 5.11 has a better name for it. Not important, but I just add it here.

The workaround works for me too, thanks! Thanks @bflanagin

jackpot51 commented 3 years ago

I have applied the workaround here: https://github.com/pop-os/linux-firmware/pull/11

We don't have the AX210 in-house, but we do have a number of other Intel WiFi cards to test with. If there are no regressions, this workaround will be released

Others on reddit with the same issue have also verified the workaround works without any side effects. Thank you for your time.

Can it be confirmed that linux-firmware 1.196+system76~1617760239~21.04~be8660e fixes this issue?

eliasfarah commented 3 years ago

Yes, working good Intel AX210 =)
