Thank you for taking care of this so swiftly. I don't believe I have much to add to the test-case. From testing locally I can see that the warnings disappear from the log and the connection _seems_ more stable. I underscore _seems_ because I have not been able to figure out which other parts of the system are actually using these particular dbus messages, if any. If nobody is actually using these, the perceived improvement could be placebo.
I will keep testing though, because I've generally been struggling with a stable wifi connection on 20.04. Thanks again. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to wpa in Ubuntu. https://bugs.launchpad.net/bugs/1879087 Title: dbus errors, frequent roaming and unstable connectivity Status in wpa package in Ubuntu: Fix Committed Bug description: * Impact extra roaming events are been generated * Test case check the wpa_supplicant log, it should have warnings dbus: wpa_dbus_property_changed: no property RoamComplete in object /fi/w1/wpa_supplicant1/Interfaces/3 the roaming events should not be too frequent * Regression potential check that wifi connection keep working correctly -------------- 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.)
