During the Setup Wizard, a speed test would have automatically run to configure your router.

After this speed test, your bandwidth speeds will be automatically input on the QoS R-App. By default, the QoS R-App is configured to give you your full speeds provided by your ISP. However, this will not necessarily give you the best experience when gaming.

If you wish to manually configure QoS for gaming follow the steps below. To learn the best configuration for maximising your speeds, check out our DumaOS Speed Guide.


The Anti-Bufferbloat feature is designed to prevent your game data from being impacted by large downloads.

To configure Anti-Bufferbloat for gaming, first open the Anti-Bufferbloat submenu and input your expected speeds.

Next, select 'Only When High Priority Traffic Detected' above the sliders. This option automatically enables Anti-Bufferbloat only when you are playing an online game. If you have a very busy home network such as a smart home, we recommend selecting 'Always' instead.

Finally, set your Anti-Bufferbloat sliders to 70% Upload and 70% Download. With this setup, whenever you play games your speeds will be throttled automatically and local congestion will be prevented.

Bandwidth Allocation

Bandwidth Allocation allows you to prioritise devices in your home and choose how bandwidth is shared.

To ensure all connected devices are efficiently sharing bandwidth, enable ‘Share Excess’ in the Bandwidth Allocation submenu for both Download and Upload.

You can allocate bandwidth using the Bandwidth Flower. By dragging the sliders for each of your devices, you can choose how much bandwidth they are allowed to use. We recommend using the Bandwidth Flower to prioritise more bandwidth-heavy devices such as PC's.

To choose an exact amount of bandwidth to allocate, click on a device name from the list. This will open a new panel dedicated to that device, allowing you to type an exact number in Mbps to allocate.

Traffic Prioritisation

Traffic Prioritization automatically detects and prioritize game traffic, ensuring that local network queues cannot cause lag in your game. To enable this feature, make sure ‘DumaOS Classified Games’ is checked (which it is by default).

You can manually add ports to Traffic Prioritization. To do this, click ‘Add Device’ and select your device from the Traffic Prioritization Selector. Then, click ‘Next’, and select ‘Advanced’ at the top. On this page you can add individual ports (or ranges of ports) to Traffic Prioritization.

If you wish to add just one port, type its number into both the Start and End boxes beneath ‘Destination Port’. For a range of ports, type the first number of the range in Start and the last number of the range in End beneath ‘Destination Port’. After this, select your protocol and click ‘Done’.

We recommend not adding any devices manually to Traffic Prioritisation as the default setting will prioritise gaming traffic for all of your devices automatically.
