Asus AX/AXE Slow Upload Speeds

[IAAI]

Does Merlin's firmware fix the issue?

Nope

at the beginning I thought it could be software bug, but after a long time missing with fw and contacting support and they give up then end up just telling me we will issue RMA just to close their support ticket.

Now I think it could be a “hardware limitation”

I would think there would be a lot of people screaming about this issue if it was wide spread.

As a result of all the testing I've done, I've believe it is thread/parallel connection related. Using Fast.com and increasing the number of parallel connections you can achieve better upload speeds. Most all the other speed tests do not have this option and must use a limited number of simultaneous connections. Why this is a problem with this router I do not know.

Ahh, @L&LD said "I am not seeing the issue in my setup with 2x RT-AX86Us." and then he linked Merlin's firmware, so I took that to meaning that Merlin's firmware fixed the issue.

 

[whitey019]

Not so. I'm now running 386.4 and the issue persists.

 

[IAAI]

I am sure the next GT-AXE86U Pro Max will fix this upload thing

 

[W3Wilkes]

Maybe it's because I only have 250Mbps service but I don't see this issue on the current Merlin firmware on my RT-AX86U.

Guess what, AP mode gives me full speed with the same exact wifi settings

used ac88 as a modem and ax86 as AP
full speed on both

What are you using as a router?

Apparently, I need to learn to read responses fully before asking questions that were actually answered in them. Appreciate your patience ;-)

No fix yet… maybe it will never happen.

Actually, you were correct in your question. A router, in his case an AC88U, is not a modem. Although a router can contain modem functions.

I am not having any bandwidth issues with my AX86U. Used as a router on Asus firmware.

Does any know if I replace the ZenWifi AX6600 for a ASUS AX6000 (RT-AX88U) will I have the same problem? Is the problem with all ASUS routers with FIOS?

 

[L&LD]

I don't know if you would have the same problems or not in your environment, but I would suggest the RT-AX86U over the RT-AX88U any day. And over any Zen products too.

Can I ask why? I'm in the process of choosing between the two and just ordered the RT-AX86U - waiting for the shipment as we speak.

 

[L&LD]

For one, I don't know your environment.

Secondly, the RT-AX86U seems to be a more finished/polished home networking router/product than the 'lifestyle' Zen products are.

If issues arise with the RT-AX86U, a fix is usually available. Can't say I've read the same experiences for Zen owners.

Oh I thought you had like a list of benefits on the AX68U over the AX88U. Sorry to assume it was so simple
I wanted the AX88U for it's looks and 8 LAN ports, but I kept reading the AX68U should be superior. I was just trying to settle myself and find some comfort in knowing I choose the right router.

I had the ax88 and now running ax86. i chose 86 because of the followings:
In terms of uploading speed they both got the same problem.
Booting up and restarts are quicker on 86.
antennas on the 86 are better.
Looks better.
I don’t need 4 more lans.
86 was cheaper.

 

[Naggert]

86 was cheaper.

Yeah 100USD cheaper for me as it was on sale. I already bought it, but I wanted the AX88 because it had 8 LAN ports and because I prefered the looks way above the AX86.
All the tests I've seen shows that the AX86 have better wifi performance and I need better wifi peformance - I can do without the 4 extra LAN ports, but I can't do with 200mbit wifi when we've got 1gbit Internet connection. I'm really excited to see how much the AX86 can pull. I'm still waiting for the package to arrive, sadly it will be atleast another week.

 

[L&LD]

Yes, it is simple.

Current Order of Recommended Routers Late 2021

Report - 2x RT-AX68U upgrade over 2x RT-AC86U in wireless backhaul mode

RT-AX86U vs. RT-AX88U

There is a reason why I sold and replaced each proceeding router with the newer model in my own home. Lower latency, higher throughput, and a more stable and reliable network. Same reasons why many customers also choose to upgrade their networks too. Some, even against my recommendations (see the second link above).
