I was wrong. MLO is now available on the Ubiquiti U7 Pro and I tested it! – MBReviews Leave a comment

I’ve retested the U7 Pro Max very not too long ago and I used to be upset by the gradual progress that Ubiquiti made in direction of the event of the MLO. Nicely, they did launch a beta firmware that helps it and I additionally managed to lastly make it work on the shopper finish, so I needed to run some assessments on the U7 Professional.

I hoped that the U7 Professional Max MLO check can be out there shortly after, however I’m not certain whether or not there’s sufficient curiosity from the customers (it’s extraordinarily time-consuming). Additionally, I’ve already run some assessments on the Zyxel NWA130BE which was a lot faster than the Ubiquiti WiFi 7 entry level to unlock this cool function, so test it out as nicely.

When you haven’t watched that video, know that I relied on a Qualcomm FastConnect 7800 adapter from MSI, and I did should run an unofficial driver replace since regardless of claiming the assist for MLO from the get-go, MSI didn’t actually allow it. In the intervening time I posted the article (three months after the video and the precise check, MSI has made the unofficial firmware replace official).

I used Home windows 11 with the experimental replace 24h2, however know that the Linux v 6.11 is now absolutely launched and will assist MLO as nicely. Once more, three months later, issues have gotten considerably higher when it comes to MLO assist.

The Ubiquiti U7 Professional is restricted by a 2.5GbE port, however I nonetheless used a 10GbE server simply to verify no bottlenecking will happen. And, to energy up the entry level, I relied on the Zyxel XS1930 change which suports PoE++ and does have a number of 10GbE Ethernet ports out there. Regardless of its age, it’s nonetheless a beast of a tool. Now, let’s see how simple it’s to arrange MLO.

When you haven’t enabled the entry to the beta firmware variations, then MLO is not going to be enabled but, however I managed to get my arms on the most recent firmware which is v7.1.24 and I may discover the MLO function below Settings and WiFi. Scroll a bit decrease and MLO will probably be there subsequent to the three WiFi Bands. Allow MLO and select which radio bands will probably be aggregated. You possibly can go for any mixture of two and even all three on the similar time.

Then, from the Radios part, you possibly can configure the channel and the channel bandwidth for every radio. Earlier than seeing the outcomes that I acquired, we have to discuss in regards to the WiFi 7 adapters as a result of not all are the identical, nor will they carry out identically.

Plainly the consensus is that the Qualcomm FastConnect 7800, the one which I’m utilizing is the very best one thus far as a result of it’s makes use of the MLMR, so we do get true multi-radio knowledge switch, supporting simultaneous Tx/Tx and Rx/Rx over a number of hyperlinks. On the similar time, as Mediatek states, the hyperlinks are statically assigned and can’t change to different frequencies dynamically, one thing that the Intel BE200 can as a result of it makes use of the eMLSR mode, an abbreviation from the Enhanced Multi-Hyperlink Single Radio.

The title offers it away that the regardless of the power to hearken to a few hyperlinks on the similar time, we’re nonetheless coping with a single radio knowledge switch. As I stated once I examined the Zyxel NWA130BE, I feel the Qualcomm method is nearer to the what MLO was initially envisioned, not that the Intel BE200 is unhealthy, fairly the opposite, apparently with the ability to present the next throughput if sure situations are met. Now let’s see the outcomes.

I needed to partially retest the U7 Professional for recent knowledge as a result of the most recent firmware updates labored in favor of a greater single-client throughput each upstream and downstream. We do see a much better throughput at 5 and 30 ft utilizing solely the 6GHz radio and the 320MHz, however even the downgrade to 160MHz didn’t have a heavy influence, particularly lengthy vary.

That being stated, I configured the MLO to make use of the 5GHz on 160MHz and the 6GHz utilizing the 320MHz channel bandwidth. And the Home windows 11 was in a position to verify that the 2 radio bands have been certainly aggregated.

They have been, after all and the efficiency is attention-grabbing, reaching the max attainable throughput throughout the 2.5GbE restrict at 5 ft, and we additionally see an enchancment at 70 ft.

When in comparison with the NWA130BE, the U7 Professional is healthier when the sign attenuation went close to 80dB, however the Zyxel entry level provided a greater throughput at 30 ft. After switching the channel bandwidth to 160MHz, we see a decline in throughput close to the entry level, however a slight improve at 70 ft, so the vary is a bit higher. The NWA130BE carried out significantly better right here.

On the following step, I configured MLO to mixture the 6GHz radio band with the two.4GHz radio, the latter utilizing the 40MHz channel width, whereas the previous remained on the 160MHz. And, when in comparison with the bottom efficiency, there’s little enchancment, solely at 70 ft. So, I enabled the 320MHz channel bandwidth on the 6GHz. This time, we do see a slight bump at 5 ft, however the remaining confirmed values decrease than the bottom 6GHz efficiency.

Let’s transfer ahead and embody all three radio bands below the MLO, organising the 6GHz to make use of the 320MHz channel width. The largest shock comes at 70 ft, the place we see a throughput near 200Mbps upstream. Downstream, it additionally did impressively nicely.

After switching the 6GHz to the 160MHz width, the close-range throughput photographs up and, whereas the sign attenuation has an additional influence on the throughput, it stays spectacular nonetheless. Lastly, I aggregated the two.4GHz radio band with the 5GHz one and, whereas it did nicely when it comes to protection, the close by throughput is missing a bit, particularly when in comparison with the Zyxel NWA130BE. It felt unusual to cease right here, particularly since I normally concentrate on latency in just about all my opinions, so I made a decision to present it a attempt right here as nicely.

However I couldn’t run net-hydra on the same old 5 shopper units. First, as a result of not all are WiFi 7 shoppers, second, as a result of it will have taken me at the very least per week of testing for about 8 hours a day. I don’t receives a commission for this, so I went with a faster resolution. I used the Qualcomm shopper system and ran Flent which checks for Bufferbloat.

And, as soon as once more, I ran it on the 6GHz radio utilizing the 160MHz and the 320MHz channel bandwidth as a reference for future outcomes. I’m going to concentrate on the common latency outcomes which appear to be higher than what I expertise utilizing the Zyxel NWA130BE. We see the curve staying beneath 50ms more often than not utilizing the 320MHz width, whereas the 160MHz reveals a median of 50ms. Does MLO have an effect when set to make use of the 5GHz alongside the 6GHz radio? Sure and for the higher.

Utilizing the 160MHz channel width, we see that the latency stays at round 30ms for the primary half of the check, then a sudden bump up, adopted by a drop at about 40ms. Utilizing the 320MHz additionally reveals an general enchancment of about 10ms throughout the whole check which shouldn’t be taken frivolously.

I did see some chaos on the obtain and add graphics, however the latency outcomes are wonderful. Subsequent, I arrange the MLO to make use of the two.4GHz radio and the 6Ghz radio bands. We will see that there’s a very slight improve in latency when utilizing the 160MHz channel width on the 6GHz radio, and a extra substantial improve when utilizing the 320MHz width, hovering at a median of 50ms.

Transferring ahead, I aggregated the three radio bands as soon as once more and ran Flent. Utilizing the 160MHz channel bandwidth on the 6GHz radio, we see a promising begin, however then the latency raises near 75ms and stays there which is way from ideally suited. Utilizing the 320MHz channel width appears to include issues significantly better and the efficiency is extra constant at round 40-45ms.

Lastly, I aggregated the two.4GHz and the 5GHz radios, and it’s a reasonably contained efficiency, the latency averaging 50ms for the whole period of the check.

That’s about all for this set of check. Do let me know if you need me to run a particular kind of check. I do have to say that I’m impressed by how a lot Ubiquiti has improved the U7 Professional, and hopefully, the U7 Professional Max as nicely, however we are going to see about that particular mannequin. Throughout my assessments, I didn’t expertise any bugs on the entry level stage and there have been no crashed whereas working the assessments.

I did expertise some cussed habits from the WiFi 7 adapter facet to detect the 6GHz radio, nevertheless it was to be anticipated contemplating that I’m utilizing an unofficial firmware model. Total, issues look good, so, when you have the best {hardware}, I’d say that the U7 Professional is a much more engaging possibility proper now than it was a number of months in the past. That’s all for now. Thanks for watching and see you subsequent time.
