Is the MLO support on ASUS routers worth it? ASUS RT-BE88U and TUF-BE3600 – MBReviews Leave a comment

After months of ready for the driver updates and the firmware upgrades to align, we lastly get to see the promised MLO function in motion. I admit I used to be skeptical that it could come in any respect on cheaper entry factors, resembling the U7 Pro and the Zyxel NWA130BE, nevertheless it’s right here and it really works higher than anticipated. Well, higher than what I noticed on each the RT-BE88U and particularly the TUF-BE3600.

I can already see the offended feedback saying that I can’t examine SMB {hardware} with consumer-grade routers and positive, I assume it’s not that truthful, however then once more, the two aforementioned routers do include a hefty price ticket, whereas additionally lacking the 6GHz radio band.

But the level will not be whether or not it is best to go along with Ubiquiti or Zyxel as a substitute of ASUS, but when the MLO efficiency is worth the additional money that’s required to get the newer WiFi 7 routers. I did check the ASUS RT-BE88U very just lately and it’s positively a novel gadget. Kind of as a result of as you possibly can see, it does have the large quantity of ports, a standard function on the RT-AX88U and the AX88U Pro.

But some are 2.5GbE, one helps 10Gbps and there’s a 10GbE SPF+ slot as properly. You don’t see that usually on wi-fi routers. So it’s not simply MLO that has been added to the RT-AX88U Pro to develop into the RT-BE88U, there are modifications in {hardware} as properly, and they do go deeper than the ports. We get extra RAM and a extra highly effective CPU which can make a distinction for demanding functions, resembling VPNs.

And then there’s the TUF-BE3600… This is the first WiFi 7 router from ASUS that I examined and I don’t actually really feel comfy calling it WiFi 7 when the 6GHz radio is lacking. Something that’s true for the RT-BE88U as properly. But, whereas the RT-BE88U nonetheless justified its price ticket with the additional options, moreover MLO, the TUF-BE3600 doesn’t. Don’t get me mistaken, it’s pretty properly outfitted, considerably much like the RT-AX86U Pro, however that’s all.

It has a bizarre form, however doesn’t actually stand out of the bunch as a WiFi 6 router, not to mention as a WiFi 7 one. Oh and it solely has one 2.5GbE port. But that price ticket, oh boy, did ASUS push it excessive. At least they did some justice to the RT-BE86U which has acquired a 10GbE port, whereas the RT-BE55U appears to be as unremarkable as the TUF-BE3600. Wait till they get cheaper as a result of they’ll in a short time. Also, make sure that to take a look at the RT-BE92U which does support the 6GHz radio.

That being mentioned, how was the MLO efficiency on the RT-BE88U and the TUF-BE3600? Let’s begin with the ASUS RT-BE88U.

I initially checked the throughput utilizing a WiFi 7 adapter and ensuring that the server connection skilled no bottlenecks (10GbE ports on either side). And, as might be seen in the graphic, we do get to see an enchancment when the 5GHz and the 2.4GHz radios had been aggregated, however solely close to the router, at about 5 toes. Moving farther didn’t make a lot of a distinction and that features the lengthy vary check, at 70 toes.

This is all upstream, whereas downstream, the enchancment can also be clearly seen close to the router, whereas farther away, the place the sign attenuation would go above 80dB, we see a less-than-impressive throughput. It’s higher not utilizing MLO in any respect on this case. This is in stark distinction with the Zyxel NWE130BE and the Ubiquiti U7 Pro which carried out so significantly better.

Then once more, these two did have the benefit of supporting 6GHz. I additionally did test the bufferbloat utilizing FLENT and should you remembered the secure 50ms (and typically much less) latency common of the two aforementioned entry factors, this isn’t in any respect the case with the ASUS RT-BE88U.

Depending on the channel bandwidth, it may possibly both keep proper under 200ms or go greater or decrease than 500ms. And that could be very removed from superb. Enabling MLO did appear to enhance issues by fairly a bit truly, however a mean of 250ms will not be one thing anybody ought to brag about. It’s nonetheless unhealthy.

And that’s utilizing both the 80MHz or the 160MHz on the 5GHz radio and the 40MHz channel on the 2.4GHz radio band. Now let’s take a look at the ASUS TUF-BE3600. Things are positively a lot totally different than earlier than.

We see that aggregating the 5GHz and the 2.4GHz radio bands doesn’t supply a greater throughput upstream, with a small exception at 30 toes. Downstream, it’s globally decrease than the single-radio efficiency.

But what was curious was that at 70 toes, the place the sign attenuation was barely above 80dB, the shopper wouldn’t see the MLO community in any respect. And it’s worrying as a result of when separated, the two radios had been certainly seen, with a usable throughput. I assume a bit extra work must be put right here by way of software program or perhaps it’s simply the {hardware} that may’t deal with the multi-link operation load.

Now let’s try the bufferbloat. I as soon as once more used FLENT and we will see that whereas the 5GHz radio was set to make use of the 160MHz channel bandwidth, the common latency is someplace round 150ms, with some regarding spikes each 10 to fifteen seconds.

Using the 2.4GHz radio, we see that the common latency is near 200ms and a bit extra secure than earlier than. Aggregating the two radio bands, we get the worse out of each worlds, about 200ms common latency and much more fluctuations, so issues don’t look good in any respect. What does that imply for us? Is the MLO efficiency sufficient to justify getting a brand new ASUS router? I can’t discuss those who support the 6GHz radio, but.

But I can say that you shouldn’t get a brand new ASUS router based mostly on MLO alone. First, as a result of the efficiency will not be that good and secondly, even when it was, paying $100 extra only for it doesn’t sit proper with me. Again, you may get higher entry factors inside the similar worth vary. Sure, you’ll want some additional tools, however the efficiency can be considerably higher. Now, is the existence of the RT-BE88U justified? This router has different benefits that far outshine its typically spotty MLO efficiency, so it does make sense so long as you want these additional options. As for the TUF Gamin BE3600 you already know that my opinion is to get one thing else if the worth is something above $200.
