Datto Networking: Routers: Quality of Service (QoS)



This article describes how to configure and implement Quality of Service (QoS) on a Datto Router.


  • Datto Routers
  • Datto Network Manager


Quality of service (QoS) lets you prioritize application traffic to ensure latency-affected data, such as VoIP and video conferencing, is uninterrupted in a congested network. You can set priorities for different traffic types handled by your router, and define their maximum bandwidth share by percentage.

See this article for QoS and other LAN settings on Datto DNA devices.


Navigating to QoS settings

In Datto Network Manager, click Routers, then select QOS from the expanded options.

Setting traffic priority

The priority fields let you specify what percentage of bandwidth to allocate to the high, medium, and low priority levels.

Application QoS

This section lets you assign the priority levels you set to each type of traffic. Click each drop-down menu and choose whether that traffic type's priority should be High, Medium, Low, or Unrestricted.
