The connman config is the same. The one iwmon snippet was with iwd masked and stopped but wpa_supplicant installed and the connect performed in connmanctl. The other is with wpa_supplicant removed and purged and iwd started, running then restarted connman then initiated a connect form connmanctl. I pored over these logs yesterday and saw a few differences, but this was one that stood out. I can look closer again tonight and see if I notice anything else that I can summarize. Keith
