Discussing your UniFi U6 Lite's power configuration settings
It only sets the power to its highest limit, which might actually degrade the signal. The goal here is to lower the output of multiple access points inside a building so they don’t clash. If your signal extends beyond what’s necessary, it can also help conserve energy and improve quality.
Lower transmit powers mean less energy usage, which keeps your AP running longer. Adjusting down works better when you have multiple APs. If they’re too strong and close together, they won’t roam well and you’ll be stuck on one AP, missing out on better coverage from the nearest one. Stronger power increases interference with nearby networks—acceptable in most homes but problematic in dense buildings. It seems this feature is independent of the UniFi Controller, so if space allows you can boost it. Performance gains are unlikely, but your devices still operate within their radio limits.
It may affect performance based on circumstances and amplifier quality. Similar to audio, pushing the WiFi amplifier near its maximum limits reduces signal clarity. You might also create more echoes inside your home; some help MIMO function while others cause interference that lowers performance instead of improving it. Trying different setups is recommended.
