How to Set Up and Manage Deco QoS Settings on the TP-Link App

Configuration Guide
Last updated: June 10, 2026

Quality of Service (QoS) is a network management feature that gives you control over your Internet experience. Think of it as a traffic director for your home network. With QoS, you can assign priority levels to your most important devices and online activities, like video calls, gaming, or streaming, ensuring they get the bandwidth they need.

This means that even when your network is busy with other downloads or devices, your high-priority tasks will run smoothly with minimal lag or buffering. To access Deco QoS settings, open the Deco app and navigate to More > QoS. Note that QoS features differ between Deco models. HomeShield models offer Scene Acceleration and Client Acceleration, while HomeCare models use a High Priority Mode.

Key Takeaways

  • QoS on TP-Link Deco lets you prioritize bandwidth for specific devices or online activities, so gaming, video calls, and streaming perform smoothly even when other devices are active on the network.
  • To find QoS in the Deco app, go to More > QoS and toggle the feature on.
  • For HomeShield Deco models, QoS offers two modes: Scene Acceleration (prioritizes specific activities, such as gaming or video conferencing) and Client Acceleration (prioritizes specific devices).
  • For HomeCare Deco models, set your Total Bandwidth, select the devices you want to prioritize, and choose a High Priority Mode.
  • You can set a time limit for how long a specific device stays prioritized by tapping the Always button next to the device in the QoS settings.

Please note that the available QoS features differ between Deco models:

  • For Deco models with HomeShield: You have access to two distinct QoS modes: Scene Acceleration (prioritizing specific online activities) and Client Acceleration (prioritizing specific devices).
  • For Deco models with HomeCare, the current QoS functionality lets you designate specific devices as high-priority and activate High-Priority Mode to ensure optimal performance.

The following section provides a detailed guide on configuring these settings for your specific Deco model.

How to Configure Deco QoS Settings

Scenario 1: For Deco models with HomeShield

Here we take Deco X50 as an example.

Step 1. To begin, open the Deco app and navigate to More > QoS, then toggle the switch to enable the feature.

Four screens: Select Scenes with custom scene, Set Scene Priority drag list, Scenes summary, and QoS dashboard with Client Acceleration.

  • Client Acceleration:

To prioritize specific devices, first select Client Acceleration, then tap Add Clients to choose all the devices you want to prioritize, and finally click Save to apply your settings.

Client Acceleration screens: Add Clients button, Select Clients list, three clients added with Save highlighted, and QoS Clients (3) highlighted.

To change how long a specific device stays prioritized, tap the Always button next to it, select your preferred duration from the options, then tap Save to confirm.

Scenario 2: For Deco models with HomeCare

Here we take the Deco M5 as an example.

Step 1. Open the Deco app, navigate to More > QoS, and click Enable QoS.

Deco app More tab with QoS highlighted, alongside the QoS intro screen with an Enable QoS button.

Step 2. After setting the Total Bandwidth, click Next. Then, select the client devices you wish to prioritize and click Add. Finally, choose a High Priority Mode, then click Done to confirm.

Three screens: Set Total Bandwidth at 500 Mbps, Select Device with a phone selected, and Set High Priority Mode with six mode options.

To change the priority duration for a specific device, click the Always button next to it, then select your desired time limit from the menu.

Two QoS screens: High Priority Devices with Always highlighted, and High Priority Duration picker options highlighted.
