I did a test of the AX58U, AX82U, and AX86U. Out of the 3 I was most surprised at the AX86U results. It performed alright, but definitely not as good as the AX82U. Any ideas? The AX82U achieved 50 Mbps+ better than the AX86U. The AX86U should be better right?

Thanks in advance!

Comparing router speed is like going fishing. In the same stream you can get big fish and small fish. Many factors affect upload/download speed from the internet. I can get 10-20 percent difference in speed test within a couple of minutes. As for the WIFI connection with AX/WIFI 6 the bandwidth from the router to the client depends on number of radios in the router and client, if DFS channels are used and the router gets a RADAR bounce, interference from other neighborhood routers and etc.

I fully understand Colin's <sigh> We get tired of explaining over and over again the inconsistencies of internet/WIFI. Speed is not important! Connection quality is important. Most Asus routers will give you GREAT connection quality. Granted, it may have to be tweaked for your environment.

I think we should number the answers to repeated questions. Put the number in a forum post title to make it easy to find. Call this one "666" ?

Thanks for the reply, bbunge. I appreciate it. I was just surprised by the results, but your answer makes sense and is helpful. It's just frustrating when you spend money on something that you believe should perform better and it doesn't appear to.

Are there any threads you would recommend reading for optimizing the AX86U?

Many thanks =D

What works for me:
Use Dual Band SmartConnect
Disable Airtime Fairness Universal Beamforming and Roaming assistant for both bands.
2.4 GHz @ 20 MHZ on channel 1, 6, or 11
5 GHx @ 160 MHZ on channel 36 (this will allow eight 20 MHz channels to be used and older clients that do not like DFS channels will still connect)
WPA2/WPA3

These settings work for me on Asus Factory Firmware and Merlin 386.2_2
Be patient after making changes as the 5 GHz will have to clear for RADAR.

Super helpful. Thanks!

I've heard a ton about Merlin. What are the main benefits of installing their firmware vs the native firmware?

If you test speed from the same location and using the same channels, and you repeatedly get the same results, then I would disagree with the <sigh> comment, I think your question is quite valid. I also disagree with the "Speed is not important! Connection quality is important.", because what is quality? Speed is measurable, and given the same speed, you usually approximately get the same quality (whatever that means) and pings. However, you cannot expect the same or better "quality" given the 50 Mbps+ difference in speed, its nonsense.

Regarding the reliability of the speed test. For example, on Speedtest.net, I constantly get the same results with a +-1% difference, at any time of the day or night, and we cannot assume that the Pavl's internet stability is different. So the "Many factors affect upload/download speed from the internet." comment is only partially true and may be not applicable to the current case, because even if this statement is true and Pavl anyway gets the same difference given the large number of tests, then, again, his question is valid.

AX82U can indeed perform better than AX86U, I've seen similar differences when comparing AX86U to AX58U and even to AX56U (when using 80MHz channels only). My impression is that the routers based on BCM675x system-on-a-chips are better performers in certain environments, maybe due to different hardware implementation or drivers, who knows.

Thank you, Volt! I appreciate your response. I was actually doing a controlled test of all 3 routers (AX86U, AX82U, AX58U) at different distances. I decided to do a reset on the 86U last night and it seems like that helped with the results. I've at least managed to get some faster results than the AX82U.

I did think it was interesting what bbunge was saying about it needing to clear for RADAR.
