ASUS RT-AX1800S Dual Band WiFi 6 vs TP-Link AC1900 Smart WiFi Router -High

Design and build quality

The ASUS RT-AX1800S Dual Band WiFi 6 features a standard router form factor with four external antennas designed to optimize signal distribution. The build includes a dual-core processor with 4 VPE, indicating a focus on handling multiple data streams efficiently. The TP-Link AC1900 Smart WiFi Router -High also utilizes external antennas and beamforming technology to focus wireless connections. While specific dimensions are not provided for either unit, both are designed for typical home placement. The ASUS model emphasizes commercial-grade security hardware integration, while the TP-Link model focuses on seamless integration with its OneMesh ecosystem for extended coverage.

WiFi Standard and Technology

A significant differentiator between these two routers is the wireless standard they support. The ASUS RT-AX1800S Dual Band WiFi 6 operates on the WiFi 6 (802.11ax) standard, which is the newer generation of wireless technology. This allows for better efficiency and throughput using MU-MIMO and OFDMA technology. In contrast, the TP-Link AC1900 Smart WiFi Router -High operates on Wave 2 wireless technology, commonly known as WiFi 5 (AC). While WiFi 5 is still capable, WiFi 6 offers improved performance in congested environments. The ASUS model supports 1024-QAM for dramatically faster wireless connections compared to the standard 256-QAM often found in older AC routers.

Performance and Speed

When looking at raw speed numbers, the TP-Link AC1900 Smart WiFi Router -High claims a combined wireless speed of up to 1900 Mbps. This is achieved through 600 Mbps on the 2.4GHz band and up to 1300 Mbps on the 5GHz band. The ASUS RT-AX1800S Dual Band WiFi 6 is rated at AX1800. Although the TP-Link number is higher on paper, the ASUS RT-AX1800S Dual Band WiFi 6 utilizes OFDMA techniques to efficiently allocate channels. This means the ASUS router can communicate with multiple devices simultaneously more effectively, potentially offering better real-world performance despite the lower marketing number. Both routers support MU-MIMO to help devices achieve optimal performance.

Ports and Connectivity

Both routers offer robust wired connectivity options suitable for most home networks. The ASUS RT-AX1800S Dual Band WiFi 6 is equipped with 5 Gigabit ports, consisting of one Gigabit WAN port and four Gigabit LAN ports. This provides 10X faster speeds than 100-Base T Ethernet. Similarly, the TP-Link AC1900 Smart WiFi Router -High features Full Gigabit Ports, including 4 x Gigabit LAN and 1 x Gigabit WAN. This allows for fast, reliable wired connections for PCs, Smart TVs, and gaming consoles. Neither router appears to include a USB port based on the provided data, with the TP-Link explicitly stating No USB Port. This limits the ability to share storage or printers directly over the network for both models.

Security and Parental Controls

Network security is a strong point for the ASUS RT-AX1800S Dual Band WiFi 6. It includes AiProtection Classic, powered by Trend Micro, to protect your home network from internet threats. Additionally, it offers ASUS Instant Guard, which provides a one-click secure VPN when away from home. The TP-Link AC1900 Smart WiFi Router -High includes Parental Controls to block inappropriate content and manage access. While parental controls are useful for family management, the ASUS suite offers broader network-level security against malware and intrusions. The TP-Link model relies on the free Tether App for management and firmware updates to keep WiFi performing at its best.

Coverage and Range

Coverage capabilities are explicitly stated for the TP-Link AC1900 Smart WiFi Router -High, which claims to cover up to 1,200 sq. ft. with beamforming technology for a more efficient, focused wireless connection. The ASUS RT-AX1800S Dual Band WiFi 6 does not provide a specific square footage claim in the available data, noting instead that actual Wi-Fi coverage will vary from network conditions and environmental factors. Factors such as the volume of network traffic and building materials will impact both routers. However, the TP-Link AC1900 Smart WiFi Router -High offers the advantage of OneMesh compatibility, allowing users to form a seamless WiFi network when working with TP-Link OneMesh WiFi Extenders to expand range if needed.

Price and Value

Price is a major consideration for budget-conscious buyers. The TP-Link AC1900 Smart WiFi Router -High is listed at $49.98, making it the more affordable option compared to the ASUS RT-AX1800S Dual Band WiFi 6, which is priced at $69.99. The $20 price difference reflects the generational gap in WiFi standards. Users seeking the lowest cost for basic gigabit routing may prefer the TP-Link model. However, the additional cost for the ASUS RT-AX1800S Dual Band WiFi 6 buys WiFi 6 compatibility and enhanced security features. For users planning to keep their router for several years, the investment in the newer standard may provide better long-term value despite the higher initial cost.

Which one should you buy?

Choosing between these routers depends on your specific needs regarding technology and budget. If you prioritize the latest wireless standards and enhanced security, the ASUS RT-AX1800S Dual Band WiFi 6 is the superior choice. Its WiFi 6 capability ensures better efficiency with modern devices, and the included Trend Micro security adds significant peace of mind. However, if you need to cover a specific area like 1,200 sq. ft. on a tighter budget, the TP-Link AC1900 Smart WiFi Router -High is a capable alternative. It offers solid gigabit performance and mesh compatibility at a lower price point. Ultimately, the ASUS model wins on technology, while the TP-Link model wins on immediate cost savings.
