Model: Archer TBE550E  
Hardware Version: V1
Firmware Version: 5.4.0.3119

I have a Win11 desktop computer with a new TP-link Archer TBE550E PCIe card.

When testing internet speed, I have a OK download speed (400 Mbit/s), but only 5 Mbit/s on upload.

When using my mobile phone from the same WiFi location, I have the same down and upload speed!

In my routers client list, I can see that my desktop is connected with AC mode, but my mobile with AX mode. I have changed in the device manager to use AX, but it still connects with AC. I have restarted everything. My router is a Icotera i4882 WiFi 6 Router. I have TP-link firmware 5.4.0.3119

Why is my desktop computer low on upload?

Hi,

 

Can you please tell us the numbers for the "Aggregated link speeds" shown by Windows 11? (within the "Properties" of the Wi-Fi connection)

  @PerLar Yes, it is 2402/2402 (Mbps)

Ok, that should mean Windows shows the connection as Wi-Fi 6, 802.11ax, because 2402/2402 is not possible in AC mode. Is that so?

 

A reported transmit link speed of 2402 Mbps usually indicates the connection is fine in the upload direction.

 

Can you try a different Internet speed test website and see if that also gives you only 5 Mbps?

Thanks, Yes that is correct. WiFi 6 and 5 GHz

 

I have tried two different speed tests - same result
