Wifi interface no longer shows

I’ve been using EOS since August with zero wifi issues until today.

That(!) seems really strange. Did you also have it running on other linux-distros?

So, today’s update of your system… as @ricklinux asked 275 posts before this one. :rofl: Check your pacman.log …

I’m out, finally.

WiFi hardware switch?? (keyboard or physical)??

I’ve been caught out by that more times than I care to admit!!

That was addressed hours ago - downgrading led to kernel panic. :joy:

There’s no wifi hardware switch.

Downgrading what? You can downgrade your whole system, or specific packes… it can be beasty to sort out, which pks. to downgrade.

This is a fresh install so rather irrelevant.

I downgraded iwd, hddata and ell as madseb suggested.

Did you update your “fresh install” yet?

Yes. Issue resurfaced before any update.

I’m beginning to suspect that systemd is the culprit.

And… AFTER any update and subsequent reboot?

Just a hunch:

You might have wpa_supplicant running as well. If that is the case there might be a “conflict of interests”.

systemctl status wpa_supplicant
systemctl status iwd

Did it work from a live image?
Does it still work from a live image?
Do you have a dual boot setup? - Does the wifi work there? (Windows?)

Maybe hardware failure…?

Only iwd is running.

@xircon - yes it worked from the live image perfectly.

@anon11595408 - sadly later updates did nothing.

Do you have a iwd.conf in /etc/NetworkManager/conf.d with the following content:

[device]
wifi.backend=iwd

?

No, but if I plug in a Ralink dongle the wifi works fine. I don’t think this is the problem.

I think this is more likely to be the issue: https://askubuntu.com/questions/1388335/intel-wifi-6-ax210-driver-issue

However, following the proposed solution there does not work for me (because it’s from a year ago and different distro). Replicating the method for Arch is beyond my technical capability. Sadly downgrading linux-firmware doesn’t fix it.

I tried a number of different fixes, including downgrading the kernel, upgrading it again (when that didn’t work), manually retrieving firmware, reinstalling network manager, wpa_supplicant and iwd… Finally, I disabled the wifi card in the Bios and re-enabled it and that seemed to work. We’ll see how long it shall last for…

It’s not perfect, but at least wifi is working. Next time I’m going to try disabling and re-enabling buggy wifi in the bios rather than putting myself through that - live and learn! Thank you @anon11595408, @pebcak,@xircon, @keithy, @ricklinux and @madseb for your patience and support during this ordeal.
