TP-Link AX5400 WiFi 6 Router Multi vs TP-Link Deco X55 Pro AX3000 Whole

Design and build quality

The TP-Link Archer AX72 Pro follows the traditional router design language, featuring a black chassis equipped with six high-performance external antennas. This form factor is designed to maximize signal propagation through physical antenna placement and beamforming technology. In contrast, the TP-Link Deco X55 Pro utilizes a modern mesh system design, typically housed in compact white towers intended to blend into home decor. The Deco system is sold as a pack, allowing for multiple units to be placed throughout a property, whereas the Archer is a single standalone unit. Build quality on both devices reflects TP-Link's standard for consumer networking gear, with ventilation designed to maintain thermal efficiency during extended operation.

WiFi Speed and Performance

When examining raw throughput, the TP-Link Archer AX72 Pro holds a distinct advantage. It operates as an AX5400 class device, offering speeds up to 4804 Mbps on the 5GHz band and 574 Mbps on the 2.4GHz band. This makes it well-suited for bandwidth-intensive tasks like streaming 8K or 4K videos and lag-free gaming in close proximity to the router. The TP-Link Deco X55 Pro is an AX3000 system, providing 2402 Mbps on the 5GHz band and 574 Mbps on the 2.4GHz band. While lower than the Archer, this speed is distributed across a mesh network, ensuring consistent performance throughout the coverage area rather than peak speed at a single point.

Port Connectivity

Wired connectivity options differ significantly between the two models. The TP-Link Archer AX72 Pro includes one 2.5 Gbps WAN/LAN port, one gigabit WAN/LAN port, and three gigabit LAN ports. This configuration supports multi-gig internet subscriptions but limits the number of high-speed wired devices to one without additional switching. The TP-Link Deco X55 Pro offers superior flexibility in this regard, with each unit featuring two 2.5G Gbps ports. This allows for superior wired ethernet backhaul between mesh nodes and supports multi-gig device connectivity such as NAS drives directly on multiple units within the system.

Coverage and Range

Coverage is the primary differentiator for these devices. The TP-Link Archer AX72 Pro relies on six high-performance antennas and beamforming technology to concentrate signals towards devices. While effective for standard homes, it remains a single point of failure for signal strength in larger or multi-story properties. The TP-Link Deco X55 Pro is designed to eliminate weak Wi-Fi and dead zones, covering up to 6500 square feet of seamless high-performance Wi-Fi 6. By using multiple nodes, the Deco system performs better than traditional Wi-Fi boosters and range extenders, ensuring consistent signal strength in every corner of the house.

Device Capacity and Efficiency

Both routers utilize modern WiFi 6 technologies to manage network traffic. The TP-Link Archer AX72 Pro employs MU-MIMO and OFDMA technology to boost throughput and efficiency. MU-MIMO allows the router to communicate with multiple devices simultaneously, while OFDMA enables sharing a single data stream between multiple devices. The TP-Link Deco X55 Pro is engineered to connect more than 150 devices with strong and reliable Wi-Fi. This high device capacity makes the Deco system particularly suitable for smart homes with numerous connected IoT devices, cameras, and personal electronics operating concurrently.

Security Features

Network security is a critical component of modern routing hardware. The TP-Link Archer AX72 Pro includes standard security protocols expected in this class, focusing on network encryption and access control. The TP-Link Deco X55 Pro highlights a specific commitment to cybersecurity, noting that TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) Secure-by-Design pledge. This indicates that the Deco device is designed, built, and maintained with advanced security principles in mind, offering users additional peace of mind regarding firmware integrity and vulnerability management.

Price and Value

Cost is a major factor for consumers choosing between a high-speed traditional router and a mesh system. The TP-Link Archer AX72 Pro is priced at $139.99, offering high-speed AX5400 performance at a competitive entry point. This represents strong value for users who do not require extensive coverage beyond a single unit's reach. The TP-Link Deco X55 Pro is priced at $199.99 for the system, which typically includes multiple units to achieve the stated coverage. While the upfront cost is higher, the value proposition lies in the elimination of dead zones and the inclusion of multiple 2.5Gbps ports across the system.

Which one should you buy?

Choosing between the TP-Link Archer AX72 Pro and the TP-Link Deco X55 Pro depends on your specific home layout and connectivity needs. If you live in a smaller space and prioritize maximum raw speed for gaming or media consumption at a lower price, the TP-Link Archer AX72 Pro is the logical choice. However, if you need to cover a larger area up to 6500 square feet, require support for over 150 devices, or want more flexible 2.5Gbps wired connections across multiple rooms, the TP-Link Deco X55 Pro is the superior investment for whole-home connectivity.
