Hi, I am facing issue with connman-1.37 regarding the wireless network access. If I restart connman that was already running, I will get not working wireless connection # connmanctl scan wifi Error /net/connman/technology/wifi: Not supported I can reproduce it on two separated Gentoo ~amd64 systems. One has Intel 9462 and the other with Intel 8265. The wireless connection never recovery unless I restart connman one more time. If I not use restart, but stop && start with sleep 3 in between for example, everything works. It looks to me like a race condition with whatever connman does to iwlwifi device upon stopping, that is still 'on going' after connmand exited, and when new one starts, it lacks code to retry bringing device up after a delay when it fails for the first time, unless it silently fails inside, somewhere. Steps to reproduce: While connman is running, run /etc/init.d/connman stop && /etc/init.d/connman start The `connmanctl scan wifi` will not work regardless of how long one will wait. The init script is the most basic one, all it does is starts/terminates /usr/sbin/connmand. Steps to reproduce with a workaround: While connman is running, run /etc/init.d/connman stop && sleep 3 && /etc/init.d/connman start The `connmanctl scan wifi` will work after a few seconds.

I'll try to reproduce it and address it if > possible. wpa_supplicant and ConnMan is a difficult topic :). What would you suggest as a replacement for wpa_supplicant? Asking because I have my one problem with patch wifi and not sure where is the problem (hardware, linux drivers, wpa_supplicant or connaman).
