Multi-Link Operation is a headline feature of Wi-Fi 7 routers, promising to send traffic across multiple frequency bands at once for faster, more stable connections. For businesses upgrading their networks, the pitch is attractive: less congestion and better reliability. But as Engadget reports, the reality is more complicated.
The term covers two implementations. The full simultaneous transmit and receive mode uses multiple radios to connect to several bands at once, while the enhanced single-radio mode switches between bands without the interruptions of older band steering. A February 2026 report from Rtings found that not a single Wi-Fi 7 router tested actually supported the full multi-radio version, so the advertised benefits are largely still theoretical.
Compatibility is another hurdle. Only Wi-Fi 7 devices can use MLO, so any laptop, phone, or access point on Wi-Fi 6 or older will not benefit. In a mixed network, enabling MLO can even introduce instability. Most routers ship with MLO disabled by default, though some ASUS models enable it out of the box.
The practical guidance for businesses is to avoid blanket recommendations. If a full Wi-Fi 7 deployment with compatible devices is in place, testing MLO on and off is worthwhile. Otherwise, leaving it disabled is the safer choice.
