The ASUS RT-AX1800S is priced at $69.99, while the TP-Link AC1200 is about 20% cheaper at $55.86. Both routers are designed to enhance home internet connectivity but cater to different user needs and preferences. The ASUS model boasts advanced features suitable for high-demand environments, while the TP-Link option offers robust performance at a more budget-friendly price.
WiFi Technology and Speed
The ASUS RT-AX1800S supports the latest WiFi 6 (802.11ax) standard, allowing for ultra-fast speeds up to 1800 Mbps. Meanwhile, the TP-Link AC1200 operates on the older WiFi 5 (802.11ac) standard, achieving speeds up to 1200 Mbps. This makes the ASUS router approximately 50% faster in terms of potential peak speed. The ASUS model utilizes MU-MIMO and OFDMA technologies, ensuring efficient data handling, especially in environments with multiple connected devices.
Coverage and Antenna Design
In terms of coverage, the ASUS RT-AX1800S features four external antennas that support its dual-band operation, while the TP-Link AC1200 also has four antennas equipped with Beamforming technology. Both routers aim to extend WiFi coverage and improve signal strength, making them suitable for medium to large homes. However, the ASUS router's advanced technologies may provide a slight edge in performance, especially in densely populated areas with multiple connected devices.
Device Connectivity
The ASUS RT-AX1800S includes five Gigabit Ethernet ports, consisting of one WAN and four LAN ports, which can support a wired connection for devices needing stable internet access. In contrast, the TP-Link AC1200 also offers four Gigabit LAN ports, making both routers well-suited for gaming consoles, smart TVs, and PCs. However, the additional WAN port on the ASUS could be advantageous for users requiring multiple wired connections.
Security Features
Security is a strong point for both routers, but they approach it differently. The ASUS RT-AX1800S includes AiProtection Classic powered by Trend Micro, offering comprehensive security features without a subscription. In comparison, the TP-Link AC1200 uses the latest WPA3 security protocol, enhancing personal network cybersecurity. While both routers prioritize user safety, the ASUS's offering may provide broader protection for users concerned about online threats.
Setup and Management
Setting up the ASUS RT-AX1800S can be straightforward, though it may require more initial configuration due to its advanced features. The TP-Link AC1200, on the other hand, boasts an easy setup process via the Tether app, available on both Android and iOS, allowing for quick network management. This ease of use can be a significant advantage for those who may not be tech-savvy or who prefer quick setups.

This makes the TP-Link model about 20% more affordable, which can sway budget-conscious consumers. However, the additional features and capabilities of the ASUS may justify the higher price for users seeking a more robust and long-term solution.
Which should you buy?
Deciding between the ASUS RT-AX1800S and the TP-Link AC1200 ultimately depends on your specific needs. If you're looking for a high-performance router with advanced features and future-proofing capabilities, the ASUS RT-AX1800S is the better choice despite its higher price. However, if affordability and ease of use are your primary considerations, the TP-Link AC1200 offers excellent value for its cost, making it suitable for general use, especially in smaller households.
