Firmware Version:

1.1.8 Build 20220321 rel.13967(4555)

Hardware Version: Archer AX90 v1.0/v1.20

I have Comcast with my ISP --> 900 Mbit/s service (fibre channel)

 

CLIENT

Model: Dell Precission 3561

 

 

 

PROBLEM

AX wifi download speeds is slow for this equipment with this price !!!

 

845 Mbps down - plugged directly to the router

430 Mbps - 5GHz-2 - client speed next to router 

 

 

I WANT TO SOLVE the 5GHz-2 (ax only) download speed issue. The Archer AX90  Tri-Band Wi-Fi 6 is NOT performing as advertised.

 

 

TP Link configuration

Disable QoS.

Change the Channel Width for the 5GHz-2 band to 160 Mhz and test:

 

 

You may check this story for additional details on 160Mhz channel width setting.

Hello  @terziyski 

I run some test, changed the the channel width to 160MHz for 5GHz-2. The result is higher a bit but still not enough. Please see the pic below:

To avoid any other conditions that are limiting your bandwidth - disable QoS on your AX90.

Here's your bottleneck according to the screenshots you posted:

 

If your Dell Precision 3561 wireless adapter is Intel Wi-Fi 6 AX201, you should be able to achieve 1200mbps on the screenshot above ( 5 GHz-2: 1201 Mbps (802.11ax) )

If you try the same with 5 GHz-1 band which is 4804 Mbps (802.11ax, HE160), you should be able to achieve full ISP speeds.

Here are the AX90 technical specs:

 

 

Since the nature of the wireless ethernet connection is half-duplex, you won't be able to utilize your full ISP speed on 5 GHz-2 band.

The QoS was switched off after you advised me it some time ago. How can I limit only to 5GHz-1 channel? How can I be connected only to 5GHz-1 with one device? Should I switch off the 5GHz-2?

Many thanks

It's easy actually - just use different SSIDs for different wireless bands. Thus you'll know to which wireless band of your AX90 you're connected at any time.

When you need a wireless client device to use your full wireless radio bandwidth connect it to the 5GHz-1 band SSID. If a wireless client device is not so bandwidth demanding, you can connect it to 5GHz-2 band SSID, to offload the 5GHz-1 band.
