I've noticed on both Android and on my NetworkManager controlled laptop that roaming between APs is not working very well. I have had to manually scan and switch an annoying amount of times throughout the day. On my Android phone it does not switch until it is completely disconnected from the internet, but that is probably the Android projects fault for leaving bgscan unset. NetworkManager sets more aggressive background roaming if the access point is using enterprise authentication[1]. The network I'm connecting to uses many different routers with the same SSID and no authentication, so this does not get set for my use case. I was told by a user on the NetworkManager irc that this problem would be better handled by wpa_supplicant. Some ideas for improving the situation: * wpa_supplicant detects if there are multiple BSS's using the same SSID on scan (or maybe connection?) and exports some boolean or property based off of that, NetworkManager then sees that the connection is roaming and sets bgscan to its more aggressive value. * wpa_supplicant detects if there are multiple BSS's using the same SSID and then changes its roaming/bgscan settings to be more aggressive. This might be difficult because it would clash with whatever is configuring NetworkManagers choice of "bgscan." It probably would make sense to allow this detection to be turned off. P.S: I'm 16 years old and have never used a mailing list before, please feel free to tell me if I did something wrong.
