What MLO means on a Wi-Fi 7 router and whether to enable it
Multi-Link Operation (MLO), a Wi-Fi 7 feature, is meant to send data across several frequency bands at once, but its benefits are still limited in practice. For most users it is safer to leave it off.
Wi-Fi 7, the latest wireless networking standard, introduces Multi-Link Operation (MLO), which manufacturers promote as a way for a router to connect to several frequency bands simultaneously and split internet traffic between them. In theory this means faster and more stable connections, but, as technology site Engadget reports, the promise has not yet been fully delivered in practice. For most users, turning MLO off is the safer choice for now.
What MLO improves
MLO builds in part on band steering, a feature of older routers that automatically moves a device between frequency bands to keep the connection as fast as possible. Switching is not always smooth: a router can get stuck on a crowded band, which slows speeds, or the connection can become unstable while it moves between bands. MLO would address both problems by sending part of the data over all three bands at once.
Why the benefits are limited
The term actually covers two different implementations. Simultaneous Transmit and Receive mode uses several radios in the router to connect to multiple bands at once, and it is the version usually advertised. Enhanced Multi-Link Single Radio mode uses one radio that constantly monitors all bands and switches to the best one, without the interruptions sometimes caused by traditional band steering. In a February 2026 report, hardware testing site Rtings found that no Wi-Fi 7 router supported the full multi-radio version.
Compatibility adds further issues. Only Wi-Fi 7 supports MLO, so devices connected to a Wi-Fi 6 or older access point get none of its benefits. If a phone, laptop or network card is not Wi-Fi 7 compatible, it cannot use MLO at all, and enabling the feature may cause network instability.
What to do
If a Wi-Fi 7 router is only part of your network, or you have no compatible devices — which describes most people — it is better to disable MLO. If your network is fully Wi-Fi 7 and you have a suitable laptop, it is worth testing performance with MLO on and off.
Settings differ by manufacturer: UniFi and eero routers offer MLO options in their apps, while Linksys places them in its web interface. MLO is usually disabled by default, but some ASUS routers ship with it enabled, so the settings are worth checking.
