A simple search across this very forum alone will show this to be untrue - quite a few others have the exact same issue, and I quoted a few before.
A faulty unit would be a good possibility however what are the chances that I got 3 faulty ASUS units, as I did test with brand new ones too?
Sure...
Netgear RS700 results in 700Mbps down and 400Mbps up on the 5GHz AX. Download is equal, upload is double that of GT-AX11000 (older hardware so ok I guess).
Netgear RS700 results in 1,400Mbps down and 800Mbps up on 6GHz AX (WiFi 6e). Download is equal, upload is 8x the upload of RT-BE96U on the...
Here's another interesting tidbit: I installed Ookla CLI on the NUC. It tests at 112 down and 800-ish up (ONT > Asus > NUC all hardwired).
I also installed iPerf on my hardwired ATV4K and it tests at 950 down and 950 up to the iPerf server on the NUC (ATV > Asus > NUC all hardwired).
This is...
This is much more in line with my expectations. I am closer to the router and also testing on AX, from 2 Apple and one HP clients.
I do live in a noisy environment though but on the other hand the router is a bit more capable and RSSIs, SNRs, and Noise levels are all excellent.
Just re-tested with an HP EliteBook 845 G8 which runs Windows 10 and has an Realtek RTL8822CE adapter, capable of 866Mbps.
Running Google speedtest I get 550 down and 90 up, running Ookla app on that same unit nets me 595 down and 92 up.
You can see below that client is connected at full speed...
Why would the expectation be that your upload is a one fifth of your download, when you should have the exact same bandwidth and capability in each direction?
I just also re-attached my NUC that I have an i7 in with 64GB RAM and 2TB Gen4 NVMe SSD running headless Ubuntu 22.04.3 LTS to the 2.5Gbit port on the Asus.
Installed iPerf in Docker on the NUC and ran down / up tests on the MacBook and on the iPhone and got similar results: fast download, slow...
I just did complete factory reset of the GT-AX11000 via control panel, afterwards wps hold, and afterwards reset via pinhole button.
Setup 3 SSIDs from scratch and connected only my MacBook to the 3rd one ("SMTEST-6G") without changing anything at all, factory setup.
Testing hardwired router...
I dumbed everything down to Verizon FIOS ONT connected to GT-AX11000 (on WAN port) and iPhone 15 Pro connected to the AX SSID. That's it.
That's the entire network at the moment. My testing environment is a NYC apartment with many neighbors' wifi networks leaking through the walls.
I still get...
Further updates. It would appear that this problem is not unique to my situation, looking at similar issues with other ASUS routers: here, here, here, here, and here.
Tried the Dual WAN workaround, that didn't do a thing. Also tried switching USB form 3.0 to 2.0 (I don't use USB), no dice.
