iwd service loses connection to public wifi after ~5 min

Hey everyone!

I've had this problem for a long time and though I've given it multiple tries, I can't seem to find a solution anywhere to this problem.

Whenever I use open wifi on transportation, the connection drops after around 5 min. regardless of usage. This doesn't happen on any other device I have, nor have I heard this happen to anyone else. I can't ping the gateway through the ip address given with ip route, but I don't exactly know if this is how it's supposed to work.

This the status log from the iwd service

I know that I'm leaking some ip addresses, but I suppose it's alright when it is a public wifi.

Unfortunately I'm not living in my public transportation, so there might be some delay before I can test your proposed solutions to my problem. Hope you can help me!

Re: iwd service loses connection to public wifi after ~5 min

The log starts w/ you restarting iwd, please post "sudo journalctl -b" for a full boot covering the problem ("… -b -2" for two boots ago)
Whatever you do, please never use "-x" because it only clutters the output w/ useless noise.

AddressRandomization=network

This is often a problem, see networkmanager wiki on randomization, so try the behavior w/ "disabled".

I'll do that in the future, thanks! Here is the "journalctl -b" for that time:

I've tried disabling it, which didn't do anything.

Re: iwd service loses connection to public wifi after ~5 min

There's a high frequency of iwd restarts - I initially thought it might relate to the dameon reload (because of the failing backup) but this here seems to be a clean incident:

I assume "passengers.t39.dsb.dk" is your public transport.

And restart IWD.

There is NOTHING in the journal segment that would remotely suggest a connection failure.
iwd doesn't register a deauthentication, there's no kernel or firmware error. Nada.

What gets us to https://wiki.archlinux.org/title/Broadcom_wireless - welcome to hell.
=> Do you have a wifi dongle (that is not! fucking! broadcom!) and that you can test in the Statsbaner to rule out (or confirm…) the NIC/driver/broadcomsituation as the direct cause?
