Wifi: Roaming Aggressiveness

Roaming Aggressiveness is a powerful but niche Wi-Fi adapter setting that controls how "eager" your device is to switch between different access points (APs). If you have a single router at home, this setting will do almost nothing; if you have a mesh system or work in a large office, it can be the difference between a seamless connection and constant lag.
