What Multi-Link Operation Does on Wi-Fi 7 Routers

Multi-Link Operation, usually called MLO, is the feature everyone talks about when they pitch Wi-Fi 7. It's the reason new routers from Netgear, TP-Link, Asus, and Eero can advertise speeds that look like marketing fiction. The thing is, most people who buy a Wi-Fi 7 router never enable MLO or never notice whether it's on. That misses the point of paying for Wi-Fi 7 in the first place.

This guide explains what MLO actually does and what kind of speed boost you should expect. It also covers which devices support it and when leaving it off is the right call.

The Old Way of Picking Bands

Before Wi-Fi 7, your phone or laptop connected to one band at a time. Either 2.4 GHz, or 5 GHz, or with Wi-Fi 6E, 6 GHz. Switching between bands required the device to fully disconnect and reconnect. That's why you'd see brief blips when walking around the house.

Routers tried to smooth this over with band steering. The router would push a device toward whichever band looked better. The handoff still took a real moment, though, and traffic in flight could drop during the switch.

The other limit was that each band has a maximum speed. Even if you had a really fast device, a 5 GHz connection topped out at whatever the 5 GHz protocol could handle that day. The 6 GHz band could go faster, but it was a separate connection. You didn't get to add them together.

What MLO Changes

MLO lets one device hold connections to two or three bands at the same time. A laptop with a Wi-Fi 7 card can pull traffic over 5 GHz and 6 GHz at once. The radio talks to both bands in parallel, and the router treats them as a single combined link.

This does two things. First, it adds raw throughput. If you can grab 1.5 Gbps from each band, your effective speed can land closer to 3 Gbps. Second, it adds reliability. If one band gets interference from a neighbor's router or your microwave, the other band picks up the slack without your device noticing.

That's the part that matters more for daily use. Most people don't actually need 3 Gbps. They do notice when video calls glitch or game packets drop. MLO makes those problems less frequent because the second band catches what the first band misses.

How Much Faster Is It Really

Benchmarks vary based on the router, the client device, and the conditions. A common pattern is that a single-band Wi-Fi 7 connection on 6 GHz gets you something like 1.8 Gbps in a clean test. That same device with MLO across 5 GHz and 6 GHz hits 2.4 to 2.8 Gbps under similar conditions.

The boost isn't a clean doubling. The radio has to coordinate both links, and some overhead eats into the gain. Even so, getting 40 or 50 percent more throughput from a feature toggle is meaningful if your internet connection can keep up.

Most home internet plans don't keep up. If you have a 500 Mbps cable plan, MLO gives you no real-world speed boost on your internet. Where it helps is for local network traffic. Big file transfers between a NAS and your laptop get faster. So does 4K streaming off a Plex server or backing up to a network drive.

What You Need to Use MLO

The router has to support Wi-Fi 7 and MLO. Almost all Wi-Fi 7 routers do at the firmware level, but some early models from 2024 had MLO disabled and added it later through updates. Check your router's firmware update history if MLO doesn't show up in the admin panel.

The client device also has to support Wi-Fi 7 with MLO. As of 2026, that includes iPhone 16 Pro or newer, Samsung Galaxy S24 or newer, and laptops with an Intel BE200 or BE201 card. Current AMD Wi-Fi 7 cards also qualify. Older devices fall back to single-band connections and ignore MLO entirely.

Both ends need to agree on the same MLO mode. Some routers offer two modes called STR (Simultaneous Transmit and Receive) and EMLSR (Enhanced Multi-Link Single Radio). STR is the high-performance one. EMLSR is the lower-power version used by phones to save battery. You don't usually have to pick. The device negotiates the right mode automatically.

How to Turn MLO On

On a Netgear Nighthawk RS series router, log in at the 192.168.1.1 login page, then go to Wireless > Advanced > MLO. Toggle it on and apply. The router will reboot briefly.

On an Asus router with the latest firmware, the path is Wireless > MLO. There's a toggle and a dropdown for which bands to bond. Most users want 5 GHz + 6 GHz bonded.

TP-Link Archer BE800 and similar models put it under Advanced > Wireless > MLO. The default is usually off in firmware until you turn it on the first time.

Eero handles MLO automatically and there's no toggle in the app. If you have a Wi-Fi 7 client and a Wi-Fi 7 Eero, MLO is active when both ends support it.

When to Leave MLO Off

MLO sounds like a pure win, and most of the time it is. There are real cases where you should leave it off, though.

Mesh nodes are the first one. If your Wi-Fi 7 router uses MLO with the main radio, mesh nodes that don't support MLO can drop their 6 GHz broadcast. Asus has this issue with AiMesh nodes from the AX era mixed with newer BE nodes. If you lose 6 GHz coverage in the room with your mesh node, turn MLO off at the main router. See if 6 GHz comes back.

Apple devices have had bugs with MLO since Wi-Fi 7 launched. Connections drop, reconnect, and drop again. Apple shipped fixes in iOS 18.3 and macOS Sonoma, and most of these have been resolved through 2025 and 2026. If you have older Apple hardware that's still acting up, turn off MLO and check that side first.

If your internet plan is under a gigabit, MLO doesn't help your internet speed. The 5 GHz band on its own already handles a gigabit just fine. Turning MLO on for a 500 Mbps internet plan adds complexity for no real gain. If something acts up after enabling it, you don't lose much by switching it back off.

What MLO Doesn't Do

MLO doesn't extend your wifi range. Both bands have the same coverage they always had, and MLO just runs them in parallel. If your laptop was on the edge of the 6 GHz signal before, it'll still be on the edge with MLO on.

MLO doesn't improve 2.4 GHz performance for IoT devices. Smart bulbs, plugs, and sensors don't speak Wi-Fi 7. They sit on 2.4 GHz like always, regardless of what the rest of the network is doing.

MLO doesn't help if your wifi card is the bottleneck. A Wi-Fi 6 laptop on a Wi-Fi 7 router still connects at Wi-Fi 6 speeds. MLO needs Wi-Fi 7 hardware on both ends.

If you've paid for a Wi-Fi 7 router and own at least one Wi-Fi 7 device, turning MLO on is usually the right call.
