Effect: Enabling allows devices that support UAPSD to save battery power by keeping their Wi-Fi radio in sleep mode for more time. Like a lot of features that are off by default, this can cause issues for some clients, especially older or IoT devices. This is another setting that relates to multicast traffic, typically coming from streaming or smart home devices such as AirPlay or Chromecast. It trades latency and support for non-registered multicast traffic for a reduction in bandwidth usage.

Google Maps Integration - Upload your own custom coverage maps or configure your map using the built-in Google Maps API. Minimum RSSI is a concept where clients will be dropped from the AP once they reach a certain threshold. This should keep clients from associating to the AP in the basement when they are on the 2nd floor, and situations like that. A good general RSSI to shoot for is around -70 dBm, but you may want to raise or lower that depending on your noise floor, network layout, and what you are trying to achieve. Wireless Uplink functionality enables wireless connectivity between APs for extended range. One wired UniFi AP uplink supports up to four wireless downlinks on a single operating band, allowing wireless adoption of devices in their default state and real-time changes to network topology. The UniFi Controller also offers configurable reporting and analytics to manage large user populations and expedite troubleshooting. Guest Portal/Hotspot support Connectivity Monitor Type controls what mesh APs attempt to reach, to determine if they are online. This is only available when wireless meshing is enabled.Wi-Fi Speed Limit allows you to restrict the amount of bandwidth available for clients connected to the network.

Broadly speaking, higher transmit power means longer range, higher signal-to-noise, and higher throughput. Higher power levels can also increase co-channel or adjacent-channel interference, so it is a balancing act. Note: A new feature added in version 7 is a warning, letting you know applying these changes is going to disrupt users that are currently connected. That’s why you might see a little triangle with an exclamation mark on the “Add New Wi-Fi Network” button in the bottom right. Effect: This enables 802.11v, which helps with saving power and the roaming process. It’s still up to the client device to support 802.11v and make a decision based on the given information. Recommendation: Leave enabled, unless you have connectivity or roaming issues. As a normal troubleshooting step, disabling band steering is a good thing to try. It’s possible that band steering causes issues for your devices on your network, even though it doesn’t cause issues on mine.This setting controls whether mDNS is enabled on the wired network, and any wireless networks that rely on it. Multicast DNS is mostly used to discover devices like a Chromecast or printer. If you have AirPlay, Chromecast, Sonos, Bonjour, or similar devices and you want to be able to discover them on other networks, Multicast DNS should be enabled. Note: Fast BSS Transition works with both pre-shared key (PSK) and 802.1X authentication methods. Older devices should not experience connectivity issues with this enabled. Effect: Enables OTA (over-the-air) Fast BSS Transition, which allows devices that support it to roam between APs faster. Without this setting enabled, roaming from AP to AP may take a few seconds, and during that time data cannot be sent or received. In most cases you won’t notice this, but latency-sensitive and real-time applications like a voice call can perform poorly. Slow roaming with a VoIP call may result in gaps in the audio. With 802.11r fast roaming enabled, the roams should be nearly unnoticeable. You’ll still want to set switch priorities individually if you have a network with several switches or links between switches. The lowest priority wins, so your core switch should be 0 or 4096, and the 2nd tier of switches should be 8192, etc. Recommendation: Turn on if battery life is important, and older/IoT device connectivity is not. Disabling this is a good troubleshooting step if you have performance or connectivity issues.

Multicast Enhancement (IGMPv3) is on under Wi-Fi settings → multicast management. This allows multicast traffic to be converted to normal unicast traffic when possible.Statistics: Ubiquiti organizes and visualizes your network(s) traffic in clear and easy-to-read graphs.
