MLO requires MS Windows 24H2 installed which supports MLO. You might be able to connect to it without that, but I don't know what would happen.

There are 2 'versions' of MLO, a 2 band (5 and 6Ghz bands) and a 3 band (2.4, 5, and 6 bands) version.

Wi-Fi 7 introduces two advanced modes of operation for Multi-Link Operation (MLO): STR (Simultaneous Transmit and Receive) and EMLSR (enhanced Multi-Link-Single-Radio).

STR (Simultaneous Transmit and Receive) allows a device to use multiple links (radios) at the same time for higher throughput and lower latency, ideal for high-performance devices like access points and laptops. In contrast, eMLSR (enhanced Multi-Link Single-Radio) uses a single radio but switches rapidly between channels by "listening" on multiple links, making it more power-efficient while providing dynamic switching for responsive performance, which is better suited for battery-powered or mobile devices.  

I am NOT sure all router's and Deco's support EMLSR.

My BE68 Deco's do. However, I can't see a true advantage using one over the other?

  @jzchen,

Yes aware of how it works, but my BE65 Deco that had MLO but only the combined 5 and 6Ghz bands. That Deco was replaced with a BE68 and it has both a 2 band and 3 band MLO.

Those 2 methods do have some difference in operation, see arxiv_org/html/2501.04149v1 for details (replace ._. with '.').

I have some issues using the 3 Band MLO... like my iPhone that can connect to the 2 Band MLO, but NOT the 3 Band MLO. My PC seems to have a problem with Screen Sharing when connected to the 3 band MLO, it takes longer to connect, and sometimes I have to restart it many time to connect to the phone. Not an issue with the 2 band MLO.

The Deco app on the phone, doesn't fully support MLO, in that it is NOT listed for a CONNECTION PREFERENCE on a device...

The TP-LINK TBE550E I have has an LED on the base, and on selection for the LED Color will indicate a 320Mhz Channel Connection that WiFi 7 can do (faster speed with wider channels).

They call that LED display 'Spectrum', like a 'rainbow' of changing color on the base. That ONLY works on the 3 band MLO, not the 2 band MLO.

Now in reading how they work, the 2 band made sense to me, each band uses a single antennae, one for in, the other for out vs. somehow sharing the 3 bands (EMLSR).

From the link above this is what they 'found':

IV Conclusion and Future Work

==========================

As I discovered, in some cases, the 2 band version is better for me, while the TBE550E conforms to the above diagram for indicating that it connected to a 320Mhz wide channel wiht the 3 band... however, I've not tested only the 6Ghz SSID on that device, my D/L speed is 5 to 10 percent faster using MLO.
