How Wi-Fi 7 MLO Combines Multiple Links
Wi‑Fi 7 introduces Multi‑Link Operation (MLO), a feature that lets compatible devices use multiple wireless links at once instead of relying on a single band. For anyone streaming 4K video, gaming online, or taking video calls in a busy apartment building, that can mean smoother performance, lower lag, and fewer slowdowns when the airwaves get crowded. This article breaks down, in plain language, how MLO “bundles” or switches between links, what needs to happen on both the router and your phone/laptop to support it, and the real‑world conditions where it helps most (and where it doesn’t). You’ll also learn practical ways to check your own network—settings to look for, quick tests to run, and signs that MLO is actually making a difference.
