Hi I am using Archer C60 V3.

Frimware Version: 1.1.0 Build 20191106 rel.36548(5553)

Hardware Version: Archer C60 v3.0

I buy this router previous month. When I enable traffic statistics and chech whether which device is using more bandwidth and there is nothing to be shown. I also enable QoS to check and limit the bandwidth but its not working anymore. I dont know whats the problem. My internet package is 4MBp/s when i download a movie IDM show the speed about 450kb to 500kb/s but in QoS its show my devices using 30kb to 40kb/s only.
