Public bug reported: When using this version of wpa_supplicant with my company WPA2-Enterprise wireless setup, I'm experiencing far too frequent roaming events (even when not moving around) accompanied by hiccups in connectivity. I also see these messages in the wpa_supplicant log:
dbus: wpa_dbus_property_changed: no property RoamComplete in object /fi/w1/wpa_supplicant1/Interfaces/3 dbus: wpa_dbus_property_changed: no property RoamTime in object /fi/w1/wpa_supplicant1/Interfaces/3 dbus: wpa_dbus_property_changed: no property SessionLength in object /fi/w1/wpa_supplicant1/Interfaces/3 Having done a little research, at least the dbus errors seem to be fixed by this commit upstream: https://w1.fi/cgit/hostap/commit/wpa_supplicant/dbus/dbus_new.c?id=23d87687c2428f3b94865580b0d33e05c03e6756 So I built a version of wpa_supplicant including this particular patch and installed on my machine. Apart from solving the dbus errors completely, it seems to have had a positive impact on the frequent roaming and unstable connectivity as well (I've run for a day with no burst of roaming events at all, where they used to happen every few minutes most of the time.)
