Multi-Link Operation (MLO) in UniFi Network

Multi-Link Operation (MLO) is an advanced feature that allows compatible WiFi 7 clients to connect to multiple wireless frequencies simultaneously on a single access point. Unlike traditional WiFi, which uses a single 2.4, 5, or 6 GHz frequency link at a time, MLO enables clients to stay associated with multiple links and select the optimal ones for data transmission. Clients will make this decision based on latency, throughput, or connection stability on the associated frequencies.

Requirements

To configure Multi-Link Operation (MLO) in UniFi Network, ensure the following:

• UniFi Network version 8.2.93 or higher
• A WiFi 7 Access Point (AP) running firmware version 7.1.18 or higher
• A dual or tri-band network (e.g., 2.4/5/6 GHz or any combination thereof)

Some examples of MLO compatible clients include laptops with Intel BE200 wireless adapters, the Samsung Galaxy S24 Ultra, and the Google Pixel 8 and Pixel 8 Pro. Currently, WiFi 7 APs do not use MLO for meshing.

Enabling Multi-Link Operation

1. Go to Settings > WiFi.

2. Choose the WiFi network you want to enable MLO on.

3. Toggle the Multi-Link Operation (MLO) switch to On.

Important Considerations

• Client Configuration:
  • MLO-enabled clients may not always show a noticeable improvement in throughput. MLO-enabled clients may be tuned for low latency or connection stability rather than speed; please check with your client manufacturers for more information.
• Client Decision:
  • The choice of which frequencies to use for optimal performance is made by the client device, not the network.
