We're using ConnMan 1.30 at the moment. Try it with a _desktop x86_64 distribution_ , with a *recent kernel* as Fedora: (WORK is gnome) https://alt.fedoraproject.org/pub/alt/live-respins/ > We've been finding some instabilities with it periodically disconnecting > from some networks.

You should use raw commands "iw" and "wpa_supplicant".
