Multi‑Link Operation (MLO) is a headline feature of Wi‑Fi 7 routers. It promises to let a router use several frequency bands at the same time and divide your internet traffic across them, which should translate into higher speeds and steadier connections. In practice, however, the technology is still in its early stages.
MLO expands on an older feature called band steering, where a router automatically hops between 2.4 GHz, 5 GHz and other bands to find the fastest path. Band steering can be glitchy; a router may linger on a congested channel or experience brief drops while switching. The idea behind MLO is to avoid those hiccups by sending parts of the data stream over three bands simultaneously. Several technical obstacles mean most users are not yet seeing the full advantage.
There are actually two ways to implement MLO. The first, often marketed as Simultaneous Transit and Receive mode, uses multiple radios inside the router to talk to several bands at once. The second, called Enhanced Multi‑Link Single Radio mode, relies on a single radio that constantly scans the spectrum and picks the best band without the abrupt handoffs that can accompany traditional band steering.
A February 2026 test by Rtings found that none of the Wi‑Fi 7 routers they examined supported the full multi‑radio version of MLO. Even if a router offers a step up from older models, compatibility remains a concern. Because MLO is exclusive to Wi‑Fi 7, mixing a new Wi‑Fi 7 router with devices that still run Wi‑Fi 6 or earlier will not unlock any of the feature’s benefits. Moreover, phones, laptops or network cards that lack Wi‑Fi 7 support cannot use MLO at all, and turning the feature on might even introduce instability.
Given these nuances, there is no universal answer about whether to enable MLO. If you are adding a Wi‑Fi 7 router to an existing network but most of your devices are still on older standards, it is safer to leave MLO turned off for now. If you have invested in a complete Wi‑Fi 7 ecosystem—including a modern laptop or other Wi‑Fi 7‑compatible gadgets—it can be worth experimenting by toggling MLO on and off to see which setting delivers better performance.
How you enable or disable MLO depends on the router brand. UniFi and eero expose the option in their mobile apps, Linksys places it in the web‑based interface, and some ASUS models ship with MLO enabled by default. Most routers keep the feature off out of the box because of older hardware incompatibility, so checking the setting is a good idea to make sure it matches your setup.
