Question ASUS USB-AX56 Wireless USB Adapter Peaks At 1.0Mbps down and 400Kbps up no matter where or what device it’s connected to

[A1ua]

I first took this device off of a family member back in November 2024. Back then and up until about February this year it’s been preforming very well, averaging over 100Mbps+ download with a great upload too. Then sometime and Feb comes around now all of a sudden it’s pulling the speeds i’ve stated in the title… Here is a list of things I’ve tried so far to no avail:

- Reinstalling the drivers
- Using the device on both USB 2.0 and 3.0 with and without the extension card
- Playing around with Wireless Mode, AdaptivityPara, EnableAdaptivity and HLDiffForAdaptivity options in it’s properties
- Using it on my laptop and running threw all the above while being close to the router (no speed changes)

Another important important note I just remembered! A couple days ago, 1 of the 2 TV’s in the house is now facing the same issue. The problem one is connected to the Router, while the other that is fine is connected to the Modem. The problem TV is getting around the same speeds as the AX56 USB wifi adapter even after hard resetting the TV and reconnecting to the router.

The router is a TP-Link Archer AX53 AX3000. The modem is a standard Starlink one.

Just connected the Wifi adapter to the Starlink modem and now it’s pulling 170Mbps on my laptop… The issue with that is my computer is too far away from the Starlink modem to stay connected and not drop out twice every minute. So any help regarding the router or Wifi adapter would be great, thanks!! (soz for long post) ᗜˬᗜ

ALSO!!! My phone and majority of other devices run fine on the router. So far I’ve only noticed the USB Wifi Adapter and the TV.

I have a Wifi card on my PC, but for a multitude of issues I am aware of (Distance, Age, Antennas, position on the motherboard), it runs pretty bad, but at least better than the USB Wifi Adapter for now.

If you look at the network status page for the wifi there someplace should be what is called a "speed" hard to say exactly where microsoft puts this so you may need to click around.

It is two number xxxx/yyyyy.

There are not really the speed when you are talking wifi they represent the data encoding method. This might give you a idea if the device thinks it has poor signal levels. Can you tell if it is connected to the 2.4 or 5ghz radio. I tend to always use different SSID so I can force things to connect where I want.

Wifi is very hard to troubleshoot everything is kept locked up in the wifi chips. Years ago you had much more access to the chips functions but the FCC wanted to avoid hackers doing stuff like increasing transmit power so they forced this lock down.

It would be really nice if they let you see the actual signal levels the device is getting on the different channels and if maybe there is more interference on one rather than the other.

The link speed? It reads 1201/1201Mbps and primarily connected to 5ghz i believe. It auto connects to 2.4ghz sometimes, but it bares no different results.

That is extremely strange. What 1201 means is you are using wifi6 using 1024 qam, 2x2 mimo, and 80mhz radio channels.

This only happens when you have a extremely good signal. qam1024 most times only works very close to the router.

You have what is called a MCS code of 11 generally when you have signal issues the router will negotiate something less complex. 11 is as high as it goes for wifi6.

So the wifi radio chip itself thinks it is getting good singals, why it will not transfer data I guess is the real question.

Do a network reset then visit www.speedtest.net and www.librespeed.org and post result links or images
