Wireless troubleshooting - how?

Hey!
I have one wireless network that I have been having issue connecting to.

I’m trying to troubleshoot but journalctl has absolutely no useful output.

Though I know connman is involved somehow the archlinux documentation on connman does not seem to match the setup on SFOS.
So:

  1. Where is the actual config of wireless neworks stored?
  2. Where is logging of attempted connections routed?

SFOS 3.3.0.16 on a F5122 (Xperia X dual sim)

OK - journalctl was apparently stuck thus no new messages were being appended.

From lsof I learnt connman stores working setups in:
/home/.system/var/lib/connman

It seems that pending configs may be stored in a tmpfs of some type /net however this folder/filesystem is not accessible from devel-su, it could also be that this is a DBUS path…

I captured wireless traffic with wireshark and am still baffled -
What I see is probe request and probe responses but it never moves beyond that.
