Model: Archer TX20E  
Hardware Version: V1
Firmware Version:

Hi, I have installed the Archer TX20E AX1800 PCIe-Card in my computer and the Download speed in my Wlan (FritzBox 5530 AX Fiber, Wifi 6) ist great, but unfortunately the Upload-Speeds are very slow and nowhere near the speeds it should get (Fiber 500/500):

 

Windows says the adapter is connected via Wifi6, 1201/1201 (Mbps) but I only get this speed:

 

Archer TX20E AX1800:

 

So basically Download-Speed is fine for me like this, but the upload speed should be much more. At the same location as the pc, with my Pixel 7 I get these speeds:

 

 

What can I do to fix the slow upload-speeds on my PC with the Archer TX20E AX1800?

 

And if I check the connection of my Desktop in my FritzBox, it doesn't show 160MHz, MU-MIMO and 11k like other Decvies, eventhough on the product-page it states that MU-MIMO is supported:

 

 

cheers

Hi, How long have you had the adapter?

Did it work the same with a different computer?

 

It is also suggested to install the following driver to see whether it helped or not:

Thank you very much and best regards.
