Network device manufacturers have made a lot of big promises about Wi-Fi 7 and one of the biggest is the potential of Multi-Link Operation. New to the Wi-Fi 7 standard, MLO is meant to allow routers to connect to multiple frequency bands simultaneously and split your internet traffic between them. In theory, that means faster internet speeds and more stable connections — but in practice, MLO is still a promise yet to be fulfilled.

MLO in some ways builds on band steering, a feature of earlier routers that lets them switch between different frequency bands automatically to offer the fastest connection. The problem is that switching isn't always flawless, which can cause slow speeds if a router gets stuck on a crowded band or instability as the router moves between them. Implemented properly, MLO would solve both of those problems by sending a portion of the data you send and receive all different three bands at once, but a few hurdles mean you're almost certainly not getting the full benefits right now.

The first problem with MLO is that the term actually refers to two different implementations. Simultaneous Transit and Receive mode is MLO as it's frequently advertised , using multiple radios in the router to connect to several bands simultaneously. Enhanced Multi-Link Single Radio mode uses a single radio that constantly monitors all available bands and switches to the best available option, but without the signal interruptions sometimes caused by traditional band steering. In a February 2026 report, hardware testing site Rtings found that not a single Wi-Fi 7 router actually supported the full multi-radio version of MLO.
