INCREASE WIFI TRANSMIT POWER ALFA UPDATE
INCREASE WIFI TRANSMIT POWER ALFA PROFESSIONAL

Use UniFi's higher capacity Professional and Enterprise switches.Both devices support large quantities of clients in addition to 2.5GbE uplink ports. Use higher bandwidth APs such as the U6 Enterprise or U6 Enterprise In-Wall.

Add more APs to better distribute connected clients.

This includes large quantities of active clients on a specific AP, or upstream switch.

Check for any upstream bottlenecks and remove them.

These can degrade over time and limit maximum bandwidth.

Try replacing the cable that connects your AP to your network.

The real throughput will always be about 50-60% lower. This describes the theoretical maximum throughput of a client given its current environment (signal strength, noise, channel width, etc.).

Check your wireless client's Maximum Phy Rate in UniFi Network's WiFi Insights tab.

If the basic optimizations above did not provide satisfactory results, follow these steps: These can often be found on the manufacturer's website.

Update the WiFi driver on affected clients.Update all UniFi APs to the latest version.To learn more about mesh WiFi considerations, click here.Although it is a convenient way to extend WiFi coverage, it is much less performant than a wired connection (about 50% lower for each "wireless hop"), especially in high-interference environments.Minimize the use of wireless meshing between APs when possible.Ensure that nearby APs are using different channel, when possible.When configuring the 2.4 GHz radio, only select from channels 1, 6, and 11.If interference levels are similar, prioritize picking the channel with the least utilization.This means selecting the highest magnitude numbers (e.g., -90 dBm is preferred to -80 dBm). Pick the channel with minimal interference for each AP's 2.4 GHz and 5 GHz radios.Perform a radio-frequency (RF) scan of your environment in UniFi Devices > select an AP > Insights > Scan Channels.Clients should have a minimum signal strength of -60 dBm, though -50 dBm or better is recommended for maximum performance.Signal Strength is shown in the WiFi Insights tab, or by clicking on a client device.Increase your client's signal strength by moving it closer to the nearest AP or adding an additional AP nearby.Set the Transmit Power to Auto for each AP's 2.4 GHz and 5 GHz radios.Individually configured in UniFi Devices > select an AP > Settings.These changes will not be applied to any AP Exclusions listed. Globally configured under Settings > WiFi > Global AP Settings.The 2.4 GHz radio should remain on 20 MHz to avoid excessive interference. Increase the channel width to 80 MHz or 160 MHz for each AP's 5 GHz radio.If you are looking for information to improve your wireless connectivity, click here. If you experience degraded connection quality (i.e., high latency or wireless disconnections), then you should consider reverting any changes and using UniFi's default settings which prioritize wireless connectivity, as opposed to speeds. This article explains the best practices for optimizing WiFi speeds.
