Hi,

I bought a new TP Link Archer AX10 (AX1500, V1.2 hardware revision) yesterday, but i already seem to encounter some issues :

Wifi : 

- The 2.4 Ghz wifi is slow for no reason, i reach an average of 50 to 90 mbps down and 5 to 18 mbps up, with a more than capable device (iPhone 13 Pro Max) right in front of the router. The issue can be replicated on other devices, including a PC with an Intel AX201 

It seems that the range of the 2.4 Ghz isn't great either, it generally seems to drop down at the same level as the 5 Ghz one, for instance if i go in my garden i'll have 2 bars/3 on both 2.4 and 5.0, and would still achieve over 200 mbps on 5.0 vs around 50 on 2.4

My ISP speeds are 400 mbps down/20 mbps up, and i have a steady close to max speed on wired or 5 Ghz.

This problem renders the 2.4 Ghz band virtually useless since i get slow speeds and better results even regarding range on 5 Ghz, and it's quite annoying since i'd like to leave only "essential" devices on 5 Ghz and everything else on 2.4

QoS : 

- I tried to set the QoS based on my ISP speeds and prioritized my main computer, but after doing so, the said computer wouldn't get more than around 15 mbps down. Why is that ? I ended up having to disable QoS

Any help is appreciated, thanks
