Wifi disconnecting (iwd)

mathbike · 2022-09-19 00:14:35

My internet is disconnecting constantly. This has been going on for months and I’ve been too busy to really get into it and learn the things I need to in order to diagnose and repair the problem. But it has recently become almost unusable. Disconnecting every few minutes. Other devices on the network do not have any issues.

To deal with it I’ve been just restarting iwd:

systemctl restart iwd.service

and that was working for a while.

I do not have another network manager (that I’m aware of) installed, and have never used anything other than iwd for wifi.

Some things:

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

How do I go about diagnosing this problem? What do I need to learn about?

That's just the head of the journal, we'll need the entire thing.
Don't copy and paste out of the pager.

To redirect the journal into a pastebin service:

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

Thank you for the response seth.

Should I just paste the link?

What exactly are we looking for?

seth · 2022-09-20 06:39:44

firmware crashes, beacon losses, … anything to explain the disconnect.
There's no indication for that in the posted log - is it supposed to cover a conneciton loss?

If not, please post an older log (eg. "… -b -1 …" for the previous one) that covers such incident.

mathbike · 2022-09-20 21:39:10

Ok, I'm not exactly sure when it's happened so I don't know which specific logs to post, so I'll just post next time it happens.

But you've already helped me a lot though because now I know where to look and what to look for.

Won't systemd-networkd.service conflict with iwd.service?

seth · 2022-09-21 05:46:27

Not unless you https://wiki.archlinux.org/title/Iwd#En … figuration
systemd-networkd doesn't manage carriers itself, https://wiki.archlinux.org/title/System … ss_adapter
