ASUS RT-AX1800S Dual Band WiFi 6 Extendable Router, Subscription-Free Network Security, Parental Control, Built-in VPN, AiMesh Compatible, Gaming & Streaming, Smart Home vs TP-Link Dual-Band AX3000 Wi-Fi 6 Router Archer AX55 | Wireless Gigabit Internet Router for Home | EasyMesh Compatible | VPN Clients & Server | HomeShield, OFDMA, MU-MIMO | USB 3.0 | Secure by Design

Performance and Speed

The TP-Link Archer AX55 delivers faster peak speeds than the ASUS RT-AX1800S, with a combined throughput of 3,000 Mbps—2,402 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band—outpacing the ASUS model’s 1,800 Mbps dual-band total. This difference stems from the AX55’s support for higher bandwidth and more advanced modulation, enabling smoother streaming, faster downloads, and reduced latency during gaming or video conferencing. The ASUS RT-AX1800S relies on 1024-QAM and MU-MIMO but lacks the same level of speed specification in its official data. For users prioritizing raw performance, especially on the 5 GHz band, the AX55 offers a measurable advantage.

Wi-Fi Technology and Network Efficiency

Both routers support Wi-Fi 6 (802.11ax), OFDMA, and MU-MIMO, which improve network efficiency by allowing multiple devices to communicate simultaneously. However, the TP-Link Archer AX55 explicitly highlights OFDMA as reducing latency and jitter, making it ideal for environments with many connected devices. It also includes Beamforming technology and four high-gain external antennas to extend coverage more effectively. The ASUS RT-AX1800S uses similar technologies but does not emphasize beamforming or antenna gain in its feature list. While both benefit from modern standards, the AX55’s focus on responsiveness and signal strength gives it an edge in dense device environments.

Security Features and Protection

The TP-Link Archer AX55 comes with HomeShield, a premium security service offering IoT device identification, security scans, basic parental controls, and quality of service management. These features are free and include weekly/monthly reports. The ASUS RT-AX1800S includes AiProtection Classic powered by Trend Micro, providing commercial-grade security, and offers a one-click secure VPN via ASUS Instant Guard. Both provide robust protection, but the AX55’s inclusion of a full suite of free tools—including device tracking and reporting—makes it more comprehensive out-of-the-box. The ASUS solution is strong but requires users to manage the VPN manually, while TP-Link automates much of the protection process.

Connectivity and Ports

The ASUS RT-AX1800S features five Gigabit Ethernet ports: one WAN and four LAN, all capable of 1 Gbps speeds—10 times faster than older 100 Mbps standards. The TP-Link Archer AX55 also includes Gigabit ports but adds a USB 3.0 port, enabling fast file sharing, printer access, or connecting external storage. This extra port provides greater flexibility for home offices or media centers. While both offer reliable wired connectivity, the AX55’s USB 3.0 port gives it a practical advantage for users who need expandable network storage or peripheral access without relying solely on wireless connections.

Design and Cooling

The TP-Link Archer AX55 features a redesigned case with a larger heat sink, specifically engineered to prevent overheating and throttling under sustained loads. This improved cooling ensures consistent performance across extended usage periods. The ASUS RT-AX1800S does not mention any specific thermal design or cooling enhancements in its product description. Given that both routers operate under similar power conditions (110–240V input), the AX55’s focus on thermal management suggests better long-term reliability in high-demand scenarios like continuous streaming or gaming.

Price and Value

The TP-Link Archer AX55 is priced at $65.98, while the ASUS RT-AX1800S costs $69.99—about 5.7% more. Over the past 30 days, the AX55 has averaged $72.87, indicating it’s currently selling below its typical price point. The RT-AX1800S averages $64.11 over the same period, meaning it’s slightly above its average cost. Despite the higher sticker price, the ASUS model offers built-in VPN and AI-driven security, but the TP-Link model delivers more value per dollar through additional features like USB 3.0 and a broader free security suite. At current pricing, the AX55 is about 17% cheaper than the RT-AX1800S relative to its own historical average.

Bestseller Rank and Market Presence

The TP-Link Archer AX55 holds a bestseller rank of #9, significantly ahead of the ASUS RT-AX1800S, which ranks #179. This gap reflects stronger consumer demand and wider market adoption. A lower bestseller rank often correlates with higher sales volume and customer trust. The AX55’s position suggests it’s more popular among buyers seeking a reliable, future-proof router with solid performance and added features. The RT-AX1800S, while well-regarded, hasn’t achieved the same level of traction in the marketplace despite its strong security offerings.

Which should you buy?

Choose the TP-Link Archer AX55 if you want faster Wi-Fi speeds, a USB 3.0 port, superior cooling design, and a broader set of free security features including device monitoring and reporting—all at a lower price than the ASUS RT-AX1800S. Its #9 bestseller rank confirms strong user confidence. Opt for the ASUS RT-AX1800S only if you prioritize built-in VPN access and AI-powered security through AiProtection Classic, and are willing to pay $69.99—$4 more than the TP-Link model—for those specific benefits. For most users, the TP-Link offers better overall value and performance.
