Minimum RSSI

What is Minimum RSSI?

Minimum RSSI is a setting on some WiFi access points that kicks devices off when their signal drops below a certain strength. The idea is to force a device with a weak connection to disconnect so it will (hopefully) reconnect to a closer, stronger access point.

Think of it like a bouncer at a restaurant who removes guests once they get too far from their table. The guest is expected to find a closer seat, but sometimes they just get thrown out and wander around confused, trying to sit back down at the same table they were just removed from.

Why it matters

In theory, Minimum RSSI solves the "sticky client" problem where devices cling to a distant access point instead of roaming to a closer one. In practice, it often creates a worse problem: reconnection loops. When an access point kicks a device off, the device does not always know where to go next. It may reconnect to the same access point, get kicked off again, and repeat the cycle.

This is especially bad for devices that do not support modern roaming protocols like 802.11v (BSS Transition). Older laptops, printers, smart home devices, and IoT gadgets are the most likely to get stuck in these loops, losing their connection repeatedly.

What you can do

• Leave Minimum RSSI disabled unless you have confirmed that all devices on your network handle it gracefully
• If you want to improve roaming, enable BSS Transition (802.11v) first; it gently suggests that devices move rather than forcing them
• Lower your access point transmit power instead of using Minimum RSSI; this naturally limits each AP's coverage area without forceful disconnections
• If you must use Minimum RSSI, set the threshold conservatively (for example, -80 dBm) to only kick off devices with truly unusable signal
• Test any Minimum RSSI changes by walking through your space with a phone and watching for disconnections
• Check that printers, smart speakers, and IoT devices still stay connected after enabling this setting

What Network Weather shows you

Network Weather detects whether Minimum RSSI is enabled on your access points and warns you if it could cause reconnection problems.
