[SOLVED] Frequent wifi disconnects after update

Ada · 2024-09-02 21:46:41

Hi all,

EDIT: just found this post which seems to have the same issue: https://bbs.archlinux.org/viewtopic.php?id=298989
seems like a problem from iwd and ell which should be solved via downgrading those two packages

after I updated my arch, I experience frequent disconnect in my home WiFi. It might reconnect after 30s or take several minutes.
This is the only device where this happens.
I have two networks running : Symbol on 2.4GHz and Symbol5 on 5GHz which might be interesting to understand the logs, as NetworkManager tries to connect sometimes one, sometimes the other.

my chip and driver:

lspci -v

03:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
	Subsystem: Intel Corporation Device 0080
	Physical Slot: 0
	Flags: bus master, fast devsel, latency 0, IRQ 91, IOMMU group 13
	Memory at fd700000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

I browsed the internet and the typical reason of conflicting services does not seem to be my problem, as NetworkManager should be the only service running

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

bluetooth.service                        | bluetooth.target.wants
cups.socket                              | sockets.target.wants

gcr-ssh-agent.socket                     | sockets.target.wants
getty@tty1.service                       | getty.target.wants
NetworkManager.service                   | multi-user.target.wants
NetworkManager-wait-online.service       | network-online.target.wants
ntpd.service                             | multi-user.target.wants
p11-kit-server.socket                    | sockets.target.wants
pulseaudio.socket                        | sockets.target.wants
remote-fs.target                         | multi-user.target.wants

however, I do see iwd throwing an error. I expected NetworkManager to call wpa_supplicant, but not necessarily iwd. Could that be an indication?
I also see "deauthenticating ... by local choice (Reason: 3=DEAUTH_LEAVING)" but cannot make sense of it.
Anything else helpful in this dmesg output?

journalctl is full with network related entries. Please find some 5 min log here (almost 1k lines but partially repetitive): https://pastebin.com/gL6L7KL5
Again, more iwd than expected.
There is also a lot

Removed BSSID ...from ignore list (clear)

Any other output that would be helpful?

Many thanks in advance for any help

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

Then see https://bbs.archlinux.org/viewtopic.php?id=298989
But wpa_supplicant also shows up in that snippet, so it's not that you configured iwd as NM backend - no idea what starts it from what we got, though.
But you don't want that to happen.

If you're gonna post the entire journal, please don't use -x (or -r), it's just spam.

Thanks Seth. Updated the post and will heed your comments on the future.

As of my problem: seems solved after upagrading iwd to version 2.20-2 as commented in the other thread.
