Initial boot and connect (device remained connected) On this run I'm seeing an agent connecting and issuing an explicit connect call rather than IWD autoconnecting. This is fine, and will create a new .open profile.

IWD will not autoconnect to a random open network without a profile. On your first boot you are forcing a connection which should generate a profile, but on the second boot no profile exists. So that is where I could check, where is the profile going? can you "ls" that directory on the _second_ boot to see if it exists? > > ----- > > @Arend: Here the requested output (debugging enabled; PATCHES ALREADY > APPLIED!). > > ----- > > tavla@tavla:~$ sudo cat /sys/kernel/debug/ieee80211/phy0/fwcap > ap > sta > wme > 802.11d > 802.11h > rm > cqa > ccx > cac > dualband > ampdu > ampdu_tx > ampdu_rx > amsdurx > amsdutx > radio_pwrsave > btamp > p2p > proptxstatus > mchan > vht-prop-rates > p2po > anqpo > txpwrcache > stbc-tx > stbc-rx-1ss > > ----- > > Best regards, > > Martin
