TX3000E slow upload speed, with excellent download speed

Model: Archer TX3000E  
Hardware Version:
Firmware Version:

I have recently installed the TX3000E and by using TCP Optimizer I have managed to get the download speeds working at full capacity on my system (around 88-99Mbps), however, upload speed remains stubbornly under 1Mbps (currently 0.8Mbps) even though the network is capable of upload speeds around 29Mbps and I am getting this on another PC next to mine (using a different Wi-fi card).

 

I have the latest drivers installed (22.70.0.6). Does anyone have any idea what to try next?

 

The Wi-Fi is supplied by TP-Link Deco M9 Plus mesh system which is optimized and working well on all other attached devices. I have TalkTalk fibre on a G.Fast connection giving 150Mbps download and 30Mbps upload generally. My motherboard is MSI H310M PRO-M2 (MS7B28) Version 2 with BIOS A.C1

@Fangorn59  Hello, 

Try to turn off Fast Roaming on Deco for a test.

And try WiFi optimizing on Deco again (Deco wifi channel may change during the optimization)

You could also test TX3000E with a hotspot WiFi or other network and see if the upload is capped within 1Mbps or not? 

When test upload, please only leave one Band turned ON at a time,either2.4Ghz/ 5Ghz. Does 2.4Ghz/ 5Ghz band upload speed perform the same. 

Can I have the photos of the speedtest on the TX3000E computer and another computer which next to it (at the same location as TX3000E), please also check the wifi link speed at the moment and let us know as well, thank you. https://www.tp-link.com/support/faq/2265/
