What does router QoS mean? Should you turn it on? My family downloaded my game and it was 460, fully understanding this switch
Router QoS is a switch that divides data into fast and slow lanes; it doesn't increase bandwidth, only determines who goes first.

However, you need to correctly fill in 85% to 90% of the measured bandwidth; if you fill in incorrectly, your whole family will see slower speed. This article clearly explains the principles, pitfalls, and the positions of various switches from different brands....
