High aggressiveness can drain laptop batteries faster because the Wi-Fi card must work harder to constantly scan for nearby networks. How to Change the Setting (Windows) How To Change WiFi Roaming Sensitivity or Aggressiveness
A balanced approach recommended for most users. what is roaming aggressiveness in wifi
Roaming Aggressiveness a setting for your Wi-Fi adapter that determines how "eager" your device is to switch from its current wireless access point (AP) to a nearby one with a stronger signal It will cling to the current AP with
At the end of the spectrum, the device is effectively stubborn. It will cling to the current AP with a "death grip," only letting go when the signal is nearly gone. The advantage of this setting is stability. In environments with high radio interference, a weak signal is often better than no signal. Constantly switching APs can cause momentary disconnections, and if a device roams too eagerly, it might disconnect from a usable signal only to find no better alternative, resulting in a "ping-pong" effect where it rapidly jumps back and forth between APs. However, the downside is severe latency. A device set to low aggressiveness will often stay connected to a distant router long after a closer one is available, resulting in slow speeds and packet loss because the device is straining to hear the distant AP. the device is effectively stubborn.
You move around a large office or house with many access points and find your device gets "stuck" on a weak, distant signal.
