Thanks!

As the Archer BE800 is one of the few routers that are "Wi-Fi CERTIFIED 7" we can actually tell from its official certificate that of all the MLO-related features talked about in that video the BE800 only supports EMLSR (Enhanced Multilink Single-Radio).

This is an incredibly pessimistic view of MLO, and what is possible to do with today's APs, just with some firmware adjustments. What RTINGS fails to cover here is that a lot of MLO's featureset is client dependent. Only a handful of clients support EMLSR, and beacon IEs do not tell the whole story of client capability and features they use. As our extensive QA labs have shown, sometimes client behavior does not even align to the intent of the manufacturer - that's why dialogue and bug reports between networking companies like Ubiquiti and manufacturers like Apple, Samsung, Intel, and others are so important. Just because a feature is advertised, for example restricted TWT, does not mean clients will take advantage of it.

EMLSR provides a huge number of benefits in a crowded RF environment: it's a huge reliability improvement by allowing clients to rapidly switch bands to optimize their connections for the lowest possible latency. Does it make your speed tests faster? No, and they're right - MLO has been marketed purely as MLMR is, bonding multiple channels for speed. But we shouldn't sleep on the capabilities of EMLSR - very rarely do clients need maximum speed for tasks like calls, posting on social media, etc, but they do need consistent low latency.

Another thing RTINGS fails to mention is that there are no current client devices, as of today, that support MLMR! This creates a catch 22 - manufacturers don't develop clients that support MLMR because there are no APs that support MLMR, and vice versa. Because MLMR utilizes multiple radios at the same time, it could have a significant impact to battery life and thermals of portable clients - there's no free lunch here, unlike previous WiFi standards upgrades where battery impact was negligible.

We at Ubiquiti are blazing our own trail by owning both the client AND access point parts of the equation. Our UDB Switch will soon be receiving a firmware update to enable multi-band, STR MLMR for its uplink. This will work with U7 Pro and other 6 GHz enabled Wi-Fi 7 APs in our lineup, just with a firmware update. Whether you bought a U7 Pro on launch day, or just got one for the holidays, we are committed to providing the best wireless featureset in the industry, and now some of the best Wi-Fi 7 client performance.

MLO is in active development on the UniFi side, with some incredible features coming in the next major release. As it is, 8.3.2 (our current GA release) brings a number of performance improvements for those existing supported clients. They did not elaborate what is missing in our EMLSR implementation, but we're always on the hunt for ways to better improve our client and user experience.

Most importantly:
"No, and they're right - MLO has been marketed purely as MLMR is, bonding multiple channels for speed."

If we start a class action suit, we would massively win or at least if people want, they can all get their money back.
Because we bought a device unable to do what was advertised.

Personally i don't care, because i know most companies (read people) have no idea what they are doing. Just take this information if you need it.

Just to be clear:

On your own website, the word AGGREGATION is used. Which would one suspect that 2.4 + 5/6 GHz is possibe.

It is NOT!

OR 2.4, OR 5.0, OR 6.0 GHz. Only faster frequency switching as you stay connected to ONE SSID.

This image has been updated from the past and is still inaccurate, even with the * and ** added.

AKA: False advertisement.

That said, even if they fix it on the router side, which with E-MLSR is not possible, there are no client devices who can Aggregate two frequencies.

For example:

Samsung S24 (any phone) on 4G mobile CAN do CA, Carrier Aggregation.
Lets say 800 + 1800 MHz and link them together.

On Wi-Fi this, for now, is NOT possible. Which was my initial question.
