Title:
  dbus errors, frequent roaming and unstable connectivity

Status in wpa package in Ubuntu:
  Fix Committed

Bug description:
  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.)
