What MLO actually does
Before Wi-Fi 7, a client connected on one band at a time: 2.4, 5 or 6 GHz. The Wi-Fi Alliance says multi-link operation supports more efficient load balancing of traffic among links, resulting in increased throughput and better reliability. Cisco Meraki's Wi-Fi 7 technical guide describes three uses for it. Aggregation combines links for more throughput. Steering moves latency-sensitive flows to the link that best serves them. Redundancy sends the same data on more than one link, so a frame lost on one can be recovered from another. [1][2]
A device that supports MLO is called a multi-link device (MLD). The router is an AP MLD and the laptop or phone a non-AP MLD. Meraki explains that association, security and encryption are handled by a shared upper MAC layer, while link-by-link work such as beacons, probes and acknowledgements is handled separately for each radio. Meraki also says MLO is mandatory for Wi-Fi 7 certification. [2]
The modes: STR, EMLSR and the rest
How much MLO helps depends on the client's radios. Meraki's guide lists the modes in the table below. It says most client vendors implement either EMLSR or multi-radio STR. EMLSR costs less and uses less power but delivers less throughput than STR. [2]
| Mode | How the client behaves | What it is good for | Status per Meraki |
|---|---|---|---|
| MLMR-STR (simultaneous transmit and receive) | Several radios transmit and receive on different links at once | Highest throughput | Commonly implemented [2] |
| MLMR-NSTR | Links must be free together before sending, which wastes airtime | - | No vendor has implemented it; not part of Wi-Fi 7 certification [2] |
| MLSR (single radio) | One link at a time, switching between them | Basic link switching | Defined [2] |
| EMLSR (enhanced single radio) | Listens on several bands, then moves all its chains to the band with a transmit opportunity | Lower power and cost than STR, with less throughput | Commonly implemented [2] |
Why the client has to support it too
MLO is negotiated between router and client. Meraki notes that an access point can run several multi-link methods at once, and the client's capabilities decide which one applies. A Wi-Fi 6 laptop on a Wi-Fi 7 router gets no MLO at all. [2]
Security is the other gate. Meraki says WPA3 and Enhanced Open are mandatory for 802.11be data rates and MLO. Protected Management Frames and beacon protection are also required. Older clients without WPA3 cannot use Wi-Fi 7 rates or MLO. GL.iNet's firmware reflects this: its MLO Wi-Fi network defaults to WPA3-SAE, which it describes as suitable for most MLO-capable devices. When 6 GHz is included, WPA3-SAE is the only option. [2][3][4]
Which devices can use it
Apple's Wi-Fi specifications page is a clear example of reading a device spec for MLO. Apple says iPhone 16, 16 Plus, 16 Pro and 16 Pro Max, the iPhone 17 models, iPhone Air, iPhone 18 Pro models and iPhone Duo support Wi-Fi 7 in the 2.4, 5 and 6 GHz bands and Multi-Link Operation. So do iPad Air (M4), iPad Pro (M5) and the M5-generation 2026 MacBook Air and M5 Pro and M5 Max MacBook Pro listed there. Other Apple models on the page use Wi-Fi 6E or earlier. [5]
The same page tempers expectations. Apple's Wi-Fi 7 rows list a maximum channel width of 160 MHz and MCS 11 (for example, 2,400 Mbps at 6 GHz). Meraki describes 320 MHz channels and 4K-QAM (MCS 12 and 13) as optional Wi-Fi 7 features, so a Wi-Fi 7 badge on a client does not guarantee them. Meraki adds that 4K-QAM needs about 42 dB of signal-to-noise, which in open spaces means being within a few feet of the access point. [5][2]
For Windows laptops and Android phones, look for both Wi-Fi 7 and MLO in the maker's specification. Wi-Fi 7 alone does not tell you which MLO mode the device uses.
Who gains now, and who is fine on Wi-Fi 6
GL.iNet lists MLO support on its Wi-Fi 7 routers, including Flint 3 (GL-BE9300), Flint 3e, Flint 4, Slate 7 and Slate 7 Pro, and Beryl 7. Flint 2 is a Wi-Fi 6 (802.11ax) router with 4x4 radios rated at 1,148 Mbps on 2.4 GHz and 4,804 Mbps on 5 GHz. It has no 6 GHz band and no MLO. [3][6]
MLO is worth paying for if you already own MLO clients, work in a busy apartment building where one band is often congested, and want EMLSR or STR to route around it. It also matters if you are buying a router to keep for many years. It matters less if most of your devices are Wi-Fi 6 or older, or if your work laptop stays on Ethernet. Those devices will connect to a Wi-Fi 7 router exactly as they would to a Wi-Fi 6 one.
Our Flint 2 versus Flint 3 comparison covers the price and hardware side of that decision. This page only explains the technology.
| Your situation | Does MLO help today? | Why |
|---|---|---|
| Mostly Wi-Fi 6 or older clients | No | MLO needs both ends to be MLDs [2] |
| One or two Wi-Fi 7 phones, laptop on Ethernet | A little, on those phones | Client mode decides the benefit [2] |
| Several MLO laptops in a congested building | Potentially yes | Steering and EMLSR or STR can avoid a busy band [2] |
| IoT devices using WPA2 only | No | MLO requires WPA3 [2] |
Questions before you decide
Does a Wi-Fi 7 router speed up my Wi-Fi 6 laptop through MLO?
No. Cisco Meraki's Wi-Fi 7 guide says the client's capabilities determine which multi-link method is used. Clients without WPA3 and Enhanced Open cannot use Wi-Fi 7 rates or MLO. A Wi-Fi 6 laptop connects to a Wi-Fi 7 router as a Wi-Fi 6 device on one band.
Which phones and laptops support MLO?
Check each maker's specifications. Apple's Wi-Fi specifications page says iPhone 16 and later models, plus the M4 iPad Air, the M5 iPad Pro and the 2026 M5-generation MacBook Air and MacBook Pro models, support Wi-Fi 7 in the 2.4, 5 and 6 GHz bands and Multi-Link Operation. Those iPhone 16 rows list 160 MHz maximum width and MCS 11, not 320 MHz.
Do I need a separate network name for MLO?
On GL.iNet's Wi-Fi 7 routers, MLO is set up as its own MLO Wi-Fi network. You select at least two radio bands, and GL.iNet says WPA3-SAE, the default, suits most devices that support MLO. Flint 2 is a Wi-Fi 6 router and is not on GL.iNet's list of MLO models.
