When devices in your home use of all of your internet bandwidth, be it from greedy downloads or concurrent video streams, this can result in network congestion.  Just like cars waiting in peak hour traffic on busy roads, network congestion causes a slowdown in the flow of information through your internet connection.  For downloads and most video streaming services that buffer ahead, you usually won’t notice short periods of network congestion.  However for time sensitive applications like multiplayer gaming, players can suffer from frustrating lag in these periods.

The Quality of Service (QoS) feature gives you hands on control to help curb this problem, by being able to set the priority and bandwidth reservation for your favourite game.

Traffic Prioritisation

Traffic Prioritisation immediately puts your gaming traffic first. 

By default, all console games and most PC games are detected and prioritised. The circles indicate when this is taking effect. You can monitor how much data is being prioritised in Traffic Overview.

  1. To add a service that has not automatically been detected, click Add Device.
  2. Select a device from the Device Selector.
  3. Select a Service or Ports to prioritise. 

Once Traffic Prioritisation is set up, we can move on to setting up Congestion Control. We must set up both of these features for QoS to be effective.

Congestion Control

QoS will automatically detect your speeds when you first start it up, but you can also manually set them using the Set Bandwidth Speeds button under the sub menu. 

If your speeds are higher than 150mbps, some QoS features can be disabled to achieve higher speeds. To do this, simply turn off Full QoS. 

To configure Congestion Control for gaming, follow the instructions below:

Select ‘Auto-Enable’ above the slider. This option automatically enables Congestion Control 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.

Set your Download slider to 70%. This is an ideal starting point, but if you experience a lot of lag, you should lower it by 10% at a time until the lag stops. After it stops, you can increase the slider by 5%, then 2%, and so on. By moving the slider and testing for lag, you can find the ideal “sweet spot” where bandwidth is maximised and lag is minimised.

From now on, when games are detected on your network, the gaming traffic will be moved to the front of the queue, eliminating lag even in tough network conditions.

Bandwidth Allocation

Some devices need more bandwidth than others, such as a PC watching Netflix. With Bandwidth Allocation, you can control how your bandwidth is shared across all of your applications or devices.

  1. In the Bandwidth Allocation submenu, you can choose either Devices or Applications to allocate bandwidth to.
  2. Drag the percentage node next to a device to give it access to more or less bandwidth
  3. Click Update Distribution to save your changes to Bandwidth Allocation.
  4. Use the Download / Upload radio button to set your bandwidth allocation for Upload. Click Reset Distribution if you want to reset your Bandwidth Allocation to default.
