[Pkg-utopia-maintainers] Bug#969319: wifi cannot connect after combined suspend & gateway reboot

[Lyndon Brown]

Package: network-manager
Version: 1.26.2-1
Severity: important

I'm on Debian Sid, with network manager configured to use iwd. I have
an Intel AX200 wifi card.

Normally the wifi of my laptop connects to my home gateway
automatically, but there's a issue where it cannot connect until
rebooted after a combined suspending of the laptop and rebooting of the
router.

My normal daily routine involves turning the gateway on first (no point
wasting electricity leaving it on over night), then getting out the
laptop and turning that on. There's no problem in this scenario. If at
any time during the day I reboot the gateway, it handles this fine (or
at least if it doesn't automatically reconnect it connects fine on
manually selecting the network from the list Gnome provides). A lot of
the time when I go off to do something else, I leave the lid open, so
no suspending, but sometimes I do close the lid and thus let the laptop
sleep, and similarly, no real issues with connecting when I get back on
it. I can select the 'turn off' wifi option and turn it back on, and it
reconnects fine.

However, something I've done instead for the past couple of nights is
to lock the user account, close the lid to let it sleep, and then turn
off the gateway. The problem I'm experiencing is that after turning the
gateway back on, and then (minutes later) returning to the laptop, it's
impossible to reconnect without rebooting. Selecting the network from
the list Gnome provides, the wifi connecting icon appears for a few
seconds, then just disappears.

Checking dmesg, this is what I'm seeing (MAC censored):

I tried turning wifi off and back on again (via the Gnome menu) and
manually selecting the network, which did not help, same failure.

I have macchanger installed, and tried switching to a new random MAC to
see if that helped (with the wifi off temporarily, obviously), but it
did not help.

I tried rebooting the gateway again, which also did not help.

I tried closing the lid for a few moments to recycle through a sleep
state, which did not help.

So I rebooted, as I did the day before when this happened, and it
connected just fine afterwards:
