Configure WiFi roaming for Gnome Network Manager

Is it possible to change/configure the WiFi roaming strategy for Gnome Network Manager? In general I would like to be able to configure how sticky it should be to connected access points (APs) and possibly give it a hint of which AP it should currently use.

For handling (wifi) connections, I'm using NetworkManager on Ubuntu 16.04.

Solution 1:

While this solution is late and temporary, one method would be to set:

wpa_cli -p /run/wpa_supplicant -i wlan0 set_network 0 bgscan '"simple:A:B:C"'

where K is how long you want to check after it has reached a certain threshold lower than B (this is based off of signal level so something like -60 would work), if anything is better than this threshold it'll search every 60 seconds instead.

So lets say you wanted your wireless card to search every 5 seconds if it has a signal level of -70, but if the current signal is better than that, search every 120 seconds, you would do the following:

wpa_cli -p /run/wpa_supplicant -i wlan0 set_network 0 bgscan '"simple:5:-70:120"'

I hope this helps, and hopefully someone can give a more efficient answer.
