How to configure an ASUS RT-AX88U router to prioritize gaming traffic for a PS5?

12 June 2024

In the world of gaming, latency is a dreaded enemy. You want your actions to translate into immediate responses on screen, but a crowded network can cause infuriating delays. If you're an avid gamer and own a PlayStation 5 (PS5), then you know the importance of a stable, high-speed internet connection.

Your router plays a significant role in ensuring smooth gaming sessions. This article will guide you through the steps to configure an ASUS RT-AX88U router to prioritize your gaming traffic, reducing lag and providing a seamless gaming experience.

Understanding Your ASUS RT-AX88U Router

Before diving into the process of configuration, it's crucial to understand your ASUS RT-AX88U router's capabilities. This dual-band wireless router is renowned for its powerful features and support for Wi-Fi 6 technology. It operates on both 2.4 GHz and 5 GHz bands, and its 8 Gigabit LAN ports let you connect multiple devices.

The router incorporates Adaptive QoS (Quality of Service), which is a feature that allows you to prioritize certain types of internet traffic. This means you can assign higher bandwidth to gaming traffic, ensuring that your PS5 gets the speed it needs for optimum performance while other devices on the network won't hog all the bandwidth.

Accessing Your Router’s Interface

The first step to configure your router is to access its web-based interface. This is where you can adjust settings and customize the router's features according to your needs.

To access your ASUS RT-AX88U router's interface, you need to connect your computer to the router's network. Open a web browser and type in "" in the address bar. This will prompt you to enter your login credentials. The default username and password are both "admin," unless you've changed them in the past.

Prioritizing Gaming Traffic with Adaptive QoS

Once you've accessed the router's interface, the next step is to enable and configure Adaptive QoS. This feature will prioritize your gaming traffic, giving your PS5 the needed bandwidth for smooth gameplay.

Locate the 'Adaptive QoS' tab on the left side of the interface and click on it. Ensure that QoS is set to 'ON'. Now, select 'Game' as the category to prioritize, as this will optimize the connection for your PS5.

Configuring Bandwidth Allocation

After setting up the QoS, it's time to manage your bandwidth allocation. This allows you to determine how much internet bandwidth should be designated to your PS5.

Under the 'Bandwidth Allocation' section in the Adaptive QoS tab, you will see your various connected devices. Find your PS5 and adjust the slider to allocate more bandwidth to it. Remember, the higher the percentage, the more internet capacity the device will receive.

Securing Your Network

Prioritizing your gaming traffic is not the only thing to consider. An unsecured network can lead to unauthorized access, which can slow down your internet or, worse, compromise your data. Therefore, you must also focus on the security of your ASUS RT-AX88U router.

Under the 'General' tab, go to 'Network Protection'. Enable the 'AiProtection' feature, which includes commercial-grade security from Trend Micro. This will provide comprehensive protection against security threats and enhance your gaming experience by keeping your network stable and secure.

Enabling Port Forwarding for Your PS5

Port forwarding can further enhance your gaming experience by reducing latency and improving connection speed. It allows your router to directly send gaming traffic to your PS5, bypassing the usual network processes that can slow it down.

Go to the 'WAN' section under the 'Advanced Settings'. Locate and click on the 'Port Forwarding' tab. Here, you will need to enter your PS5's IP address and then specify both the internal and external ports which need to be forwarded. For PS5, the ports that you need to forward are:

  • TCP: 80, 443, 3478, 3479, 3480
  • UDP: 3478, 3479

Once you've entered these details, save your settings. Now, your router will prioritize the gaming traffic from your PS5, reducing lag and improving your overall gaming experience.

In essence, the ASUS RT-AX88U is a powerful router with a range of features designed to support heavy-duty tasks like gaming. By following the above steps, you can harness the full potential of this router and create an optimized, high-speed network for your PS5. Happy gaming!
