The AC88U uses all the 8 ports, of the switch chip or it may have 2 switch chips (i havent seen the architecture yet).

The RT-AC88U adds an RTL8365MB, which handles four of the 8 LAN ports.

How are the switch chips connected? Do they have a 1Gb/s link between them or a 4Gb/s link? Or are they connected like the mikrotik RB1100AHx2?

More interesting to me is the major gains of the newer model came from the beamforming feature. Without it the results were only about 5% apart, well within the probable margin of error. And there lies the advantage of systematic testing over anecdotal comments. I had hoped that the newer routers might benefit from better circuit design or higher quality fabrication, but without that particular feature there is little difference.

I don't think you told us what your client was that you used in the garage?

Is it an AC class client? How many streams / antennae? Hand held device or an AC (wall powered) laptop?

You believe that less than 10% difference is not significant. I disagree with that, in theory.

I think the large improvements of the beamforming feature is directly related to the better design (both hardware and firmware). It just doesn't offer much when it is disabled.

Asus hasn't revealed it, but since the RTL8365MB only has an RGMII interface, I assume that's how it's linked to the other switch.

The greatest improvement was beamforming in the AC68U -- 39% better speed on 5G.

Next biggest was replacing the stock 5dBi antenna with 9dBi (advertised) -- 28% improvement on 2.4G.

Because of the variability of the test measurements differences smaller than 8 or 10% are probably not statistically significant. I'm not going to bother running a full statistical panel on these but from years of experience analyzing lab measurements that's a pretty good guess.

My 7-word summary from all of this is "turn beamforming on and use good antennas."

Nice work.

I would guess 5G is with 802.11ac explicit beam forming. Your result suggests that it's working so well that it overshadows any gain from using a 9dBi antenna. While on 2.4G, universal beam forming is used which helps but does not work as well as explicit beam forming. The gain from a 9dBi antenna is more prominent.

Slightly off topic: while most discussions on this forum essentially focus on PHY layer to improve range (and throughput), little discussion on MAC layer. I don't know if it's due to less tweaks possible on MAC or lack of expertise on this aspect. E.g. 10% increase of MAC efficiency on a 1300Mbit/s link is a whopping 130Mbit/s increase in throughput at your best spots.

I read on another thread some folks can achieve 90% utilisation of link rate.. lol.

That was a topic of exploration some time back - bonding two layer 2 AC1300 connections across a WiFi bridge with two AC3200's, but the firmware wasn't capable back then, and it's likely not capable now...

I would guess you didn't catch what he was thinking. lol. I bet he meant to connect two AC5300 routers by ethernet cables. And here was his reasoning: AC5300 => 5.3Gbit/s total throughput. One gigabit ethernet port provides 1Gbit/s. 5.3Gb1 requires 5 to 6 ports to make most effective use of all throughput.

Hence, 4 ethernet ports are definitely not enough for bridging two AC5300 routers, not to mention leaving some ports for other devices. Whether link aggregation like this is possible or not is another topic..lol I had too much time reading into junk!

No - it was a thought experiment about how to bind the two 5GHz radios on the layer two as an ethernet bridge using the linux bonding driver - the Asus firmware basically can't handle that...

two AC1300 3*3:3 streams would have been interesting...

seems reasonable and practical...

Would be nice if Asus turns up the interesting things on the RTL... it has management capabilities on the layer 3...

Guys how are you?

Can someone tell me a place I can buy this router and be shipped to Brazil? Amazon and Newegg both sites have the router but won't ship worldwide this one.....

Thanks

Maybe because I'm at the phone, sorry

Just a question, I can't find the support page at Asus website to download the fws for this one, where can I find the latest firmwares from Asus to the 5300?

Thanks

Asus hasnt put it live yet.

So for now or I use the one that comes with router or I need to use this latest beta right?

yes, although the one I posted shouldnt be a beta. beta firmware usually starts with a 9, official firmwares start with a 3. So the one I listed is official, I just dont think its been released on the automatic download servers.

Do you guys think that my 9dBi antennas that I bought for my N66U will work for the 5300 and if they do will the router benefit from it if I replaced only 3 of them with it?

I did get two different routers over the past few weeks (one of them is a new hardware revision of a previous model, which will require firmware-level changes). I haven't received an RT-AC5300 most likely because the hardware is virtually identical to the RT-AC88U, so it might not be necessary. The main reason why I haven't blindly tried to support it yet (like I did for the AC3100) is the absence of GPL for that specific model.

Beside, the two shelves devoted to my mini lab setup are getting a tad crowded right now.

Regardless of the fact that the specs match the AC88U, they should still send you another unit. Whether you choose to support it or not is entirely up to you.

They all need to match... you'll need four at least

Not entirely sure, here is the only listing I found regarding the antenna on the 5300 from the manual.
