In practice if this is not enabled, a small Raspberry Pi connected to a far-away AP at 54Mbps will drag every other connected device's effective bandwidth down to 54Mbps until the Pi is powered off or moved to a different AP. This ensures that the access point shares data between connected clients on a time division multiplexing basis, rather than the default which allows a certain amount of bandwidth to be transferred before moving on. This ensures that clients will connect on the 5GHz channel when available.ĭevices > YOUR-ACCESS-POINT-HERE > Config > Airtime Fairness Ensure Band Steering is set to Prefer 5G.This is outside the scope of this doc.ĭevices > YOUR-ACCESS-POINT-HERE > Config > Band Steering Even if you only have one access point, plan what frequencies are around you using a third party WiFi scanner on Android or the AirPort Utility app on iOS to. Run a WiFi scanning utility and pick the least congested channel. Radio 5G should be set to VHT80 or VHT160 (HD series)Įnsure Transmit Power is set to the following.This is a great feature, but I found it to be choosing channels that were DFS (radar in the area causes intermittent dropouts of your network) or just not selecting channels 1 / 6 / 11.ĭevices Devices > YOUR-ACCESS-POINT-HERE > Config > RadiosĮnsure Channel Width is set to the following For many Apple / iOS devices, this causes them to not sleep correctly which both causes anomalies on the dashboard and kills the device battery life. This is the interval in which the access point polls the devices to check if they're alive. With these optimised settings you'll see devices always prefer 5GHz, and at the time of writing, the current method to detect 'high performance clients' is not reliable.Įnsure DTIM Mode default values is disabled With these optimised settings you'll see devices only using 2.4GHz if they either a) don't support 5GHz (thanks Google!) or b) are too far away to maintain a reliable connection.Įnsure Connects high performance clients to 5 GHz only is disabled It creates a lot more 'noise' on the dashboard in the form of anomalies when you have more than one access point within a home environment, and is useless if you only have a single one.Īt the time of writing it's also a BETA feature.Įnsure Combine 2 GHz and 5 GHz WiFi Network Names into one is enabled Settings > Wireless Networks > YOUR-NETWORK-HERE > Edit This allows you to follow along with the guide in it's entirety.Įnsure Automatically Optimise Network and WiFi performance is disabled Settings Settings > SiteĮnsure Enable Advanced Features is enabled Click here for an updated version.īelow are the key settings that I apply on any unifi installation for optimal performance.
