Once the RSSI crosses the threshold set by your roaming aggressiveness level, the device background-scans for alternatives.
On – Via iwconfig or wpa_supplicant (e.g., bgscan parameters).
Wireless devices continuously measure the strength of their current connection using Received Signal Strength Indicator (RSSI), which is calculated in decibels milliwatts (dBm). what is roaming aggressiveness in wifi
Prompts the device to switch APs more frequently. Ideal if you walk around a lot.
: If your laptop stays connected to a weak signal from a router in another room even when you're standing next to a closer one, increasing aggressiveness can help it switch faster. Once the RSSI crosses the threshold set by
Understanding Roaming Aggressiveness in Wi-Fi Wi-Fi roaming aggressiveness is a configuration setting that dictates how quickly a wireless device disconnects from its current access point (AP) to search for a stronger, closer signal from another AP on the same network. This setting directly controls the decision-making threshold of your device’s network interface card (NIC). It determines whether your device clings to a fading signal or aggressively jumps to a better one.
Enterprise Android devices sometimes feature these settings in developer options or specialized MDM (Mobile Device Management) profiles. For consumer phones, the behavior is locked by the manufacturer to protect battery life. Network-Side Alternatives Prompts the device to switch APs more frequently
You experience dropped calls or choppy Zoom meetings when walking from room to room.
If you are constantly experiencing slowdowns in specific areas of your house or office, try increasing the Roaming Aggressiveness to or Medium-High .
Most modern routers broadcast two bands: (long range, slow) and 5 GHz (short range, fast). If your Roaming Aggressiveness is set to High , your device will constantly try to jump to 5 GHz. But because 5 GHz has shorter range, you might ping-pong between bands.
The device becomes proactive. If the current signal drops even slightly below peak performance, the device begins scanning for a cleaner, stronger alternative. 5. Highest
