The Archer AX55 is based on next-generation 802.11ax Wi-Fi technology, elevating your Wi-Fi experience while remaining backward compatible with 802.11a/b/g/n/ac Wi-Fi standards. The QoS feature of this device allows you to reserve bandwidth for specific devices or applications. By recognizing application and device information as well as bandwidth requirements, it ensures that high-priority data automatically receives the best possible connection. QoS also ensures that lower-priority applications, such as file downloads, never come to a complete halt. This guarantees reliable performance for critical applications even during high network congestion.
