This means that older devices can take up more airtime on the network, slowing down performance for everyone else. Airtime fairness works by limiting the amount of airtime that older devices can use. This ensures that newer devices have enough airtime to operate at their full potential. The UniFi Network Controller allows you to enable airtime fairness for each of your UniFi AC Mesh units. When airtime fairness is enabled, the AC Mesh unit will prioritize traffic from newer devices over traffic from older devices. This helps to improve overall network performance and provides a better experience for everyone on your network. Minimum RSSI (Received Signal Strength Indication) is a setting that allows you to kick off devices with weak Wi-Fi signals. Devices with weak signals can often cause problems on a network, such as slow speeds and dropped connections. By setting a minimum RSSI threshold, you can ensure that only devices with strong signals are allowed to connect to your network. The UniFi Network Controller allows you to set a minimum RSSI threshold for each of your UniFi AC Mesh units. When a device's signal strength falls below the threshold, the AC Mesh unit will automatically disconnect the device from the network. This helps to improve overall network performance and provides a more stable experience for everyone on your network. Regularly reviewing your settings and making adjustments as needed is essential for maintaining optimal network performance. Network conditions can change over time, so it's important to periodically review your settings and make adjustments as needed to adapt to these changes. For example, you might need to adjust your channel selection if you notice increased congestion on your current channels.
