Dear
I am experimenting with dynamic behaviour of NM with multiple networks and how
handover occurs between WiFi/mobile network. I am moving away from the WiFi
access point as far that the NM is unable to connect to the WiFi. NM is
restarted and gets a connection to the mobile connection (lowest autoconnect
priority). Afterwards, I am moving very close to the WiFi AP but NM doesn't
connect to it.
If I execute "nmcli dev wifi list" after moving a little bit from the APs away,
I get:* SSID MODE CHAN RATE SIGNAL BARS SECURITY
demo7 Infra 7 54 Mbit/s 22 ▂___ -- STATION
Infra 1 54 Mbit/s 14 ▂___ WPA2 802.1X CONTROL Infra

This shows me that both station APs (SSID=STATION) have signal of 14% and 19%.
If I am executing "Service network-manager restart" and again ask the WiFi
signal level with "nmcli dev wifi list", I get:
* SSID MODE CHAN RATE SIGNAL BARS SECURITY

Mbit/s 35 ▂▄__ WPA2 802.1X
My robot is not moved but signal level after NM restart is noticeably higher
than before. It seems that the signal level sticks to the percentages which
have been measured at the beginning of my experiment.
Can someone help me with this issue?
Best regardsPieter Cardoen
