I’m using the TP-Link Archer AX53 Indian Version (Hardware V1.8) and noticed that the WebUI does not include any QoS settings, even though QoS is available in the TP-Link Tether app. When I enable QoS through the app, the connection becomes unstable — my loaded latency jumps from the usual 40 to 60 ms but when i enable qos  the loaded latency goesto 120–225 ms, making it unusable for gaming and other real-time tasks. Without QoS, the router performs normally. Since QoS is an important feature for managing bandwidth and ensuring stable latency, please add full QoS controls directly to the WebUI and improve its stability on the AX53 Indian variant. This would greatly enhance usability and performance for many users. I have a archer c6 that have better loaded latencyof 5ms 

i am sharing the results too in link
