A QoS “Quality of Service” feature in a router improves online gaming and other multimedia operations by prioritizing the gaming traffic over any network traffic. It is used for gaining the best performance and improving surfing over the Internet by automatically setting the priority level for commonly used applications. You can disable or configure the QoS using the dlinkrouter.local interface while surfing the Internet. <br>Website: [a]https%3A%2F%2Fdlink-router-local.com%2F[/a]
