i checked my journalctl -b and i could see constant errors like this

That's not a error - wpa logs signal quality changes (the signal quality is ok)

This is kinda normal because NM enabled wpa_supplicant's debug output, but the 3s frequency there is excessive.
The trigger might be some power saving or roaming or whatever causing frequent reconnects.

Please don't grep for random strings, post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

read the note

seth · 2026-01-11 11:24:54

Which one? This has nothing to do w/ resolved.

Disable systemd-networkd, but I doubt that to be the cause either.

cat /proc/$(pidof wpa_supplicant)/cmdline

It would seem either you or NM have risen the debug level, there's nothing else to explain the excessive signal logging.

so was there a problem within the wpa_suplicant from core. and should i change it to one from core testing brach.

seth · 2026-01-11 13:58:40

and should i change it to one from core testing brach.

No, see https://wiki.archlinux.org/title/Offici … positories
In doubt wait.

Unlike the wiki note the merge request is relevant but it was opened 7 months ago and I haven't seen this excessive signal reports during that time (or ever) - but it might be chip dependent.
Upstream patch is https://git.w1.fi/cgit/hostap/commit/wp … 2d9c69166a

i think the core-testing did the work for now
this is the log now : http://0x0.st/PXeb.txt

For clarification: Do not cherry pick stuff out of the testing repos!
You can switch to ALL packages from ALL testing repos or none at all.

Picking isolated packages *can* work at times but also *can* (more often than never) result in major issues and is generally a terrible idea.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Thanks.

So should i stick with the core and build only the wpa_suppliacnt from the testing.

That's exactly the opposite of what seth said.

To add some context, also for future readers:
In this particular case, looking at the build history and dependencies of wpa_supplicant:
Using the binary from the testing repo is unlikely to cause any further problems - and after all it's your system and you can do whatever you want.

What you need to understand is that this isn't a reasonable general strategy and the rule of thumb is that
if you've to ask, you better do not dive into the testing repos
(let alone cherry picking it) because you're unlikely prepared to deal with things going wrong (which will more typically be the result)

More experienced users (and certainly the developers/packagers) might very much habitually break these guidelines, but they will also then not show up on the forum because their system no longer boots.
They know what they're doing, understand what the potential consequences are, how to safeguard that and in doubt get out of the mess they created.

akai · 2026-01-11 15:02:11

mm. OK

wait till the package hits the main core repo unless your competent enough to mix and match testing packages with non testing packages, theres always a chance you can run into dependency issues down the road, there are a few example threads on the forums showcasing this e.g. https://bbs.archlinux.org/viewtopic.php … 7#p2282077

but really, if the testing package is working fine for you then i don't see a reason why you can't use it, as long as you disable the testing repos and move back to the package in the core repository after that version moves there it's fine

on a side note i wonder why wpa supplicant is in core when alternatives like iwd are in extra lol

I was gonna say because iwd depends on other pacakges from extra, but wpa_supplicant depends on https://archlinux.org/packages/extra/x86_64/pcsclite/
So … for traditional reasons and cultural heritage

Ok so i changed from wpa_supplicant to iwd as Network manager backend. And removed wpa_supplicant.

well thats one way to fix it, for correct configuration with networkmanager see:
