WiFi not roaming to a much stronger/faster AP

[Michał Sawicz]

I have spotty WiFi reception around the house, and I've noticed that once I roam to a 2.4GHz because I've moved out of range, coming back I'm stuck at it with very low signal despite there being much more powerful and faster BSSIDs around.

`nmcli d wifi` reports:

$ nmcli d wifi
IN-USE BSSID SSID MODE CHAN RATE SIGNAL BARS SECURITY
        74:83:C2:19:7E:BA wifi Infra 1 130 Mbit/s 82 ▂▄▆█ WPA2
* 74:83:C2:19:7E:BB wifi Infra 44 540 Mbit/s 55 ▂▄__ WPA2
        4C:E6:76:F9:5E:AF wifi Infra 52 130 Mbit/s 39 ▂▄__ WPA2

If I didn't reconnect, I'd be stuck on the 4C: BSSID still.

I am no wifi expert, but seems like roaming is controlled by WPA or IWD?
