Speed and Performance
The ASUS RT-BE86U outperforms the TP-Link Deco X55 Pro in terms of speed, achieving a maximum throughput of up to 6800 Mbps compared to the TP-Link's 3000 Mbps. This substantial difference makes the ASUS router a superior choice for users engaging in bandwidth-heavy activities such as online gaming or 4K streaming. The ASUS router also supports advanced technologies like 4096-QAM and Multi-Link Operation, ensuring optimal performance across its dual bands. While the TP-Link system provides reliable performance for everyday use and can handle multiple devices, the ASUS offers a significant edge for high-performance demands.
Coverage Area
When it comes to coverage, the TP-Link Deco X55 Pro excels with its ability to blanket up to 6500 square feet, accommodating larger homes and eliminating dead zones. In contrast, the ASUS RT-BE86U provides coverage up to 2750 square feet but can be expanded through AiMesh technology by adding other ASUS routers. This flexibility allows users to tailor their network to specific space requirements. For those needing extensive coverage without additional hardware, the TP-Link system stands out as the more suitable option.
Connectivity Options
The ASUS RT-BE86U features one 10 Gigabit WAN/LAN port, enabling high-speed wired connections, alongside additional capabilities for 4G LTE and 5G mobile tethering. This versatility is essential for users with high-usage scenarios or those requiring robust wired connections. On the other hand, the TP-Link Deco X55 Pro comes equipped with two 2.5G WAN/LAN ports, catering to multi-gigabit internet services and wired Ethernet backhaul. While both routers provide advanced connectivity options, the ASUS router's superior port speed makes it a better fit for users seeking top-tier wired performance.
Device Handling Capacity

The TP-Link system can support over 150 devices simultaneously, making it ideal for households with numerous smart devices and users. The ASUS router, while powerful, is better suited for environments where fewer devices are connected simultaneously. If you prioritize connecting a large number of devices without compromising performance, the TP-Link Deco X55 Pro is the more capable choice.
Security Features
Both routers offer robust security measures, but they approach it differently. The ASUS RT-BE86U features AiProtection Pro powered by Trend Micro™, providing lifetime security with one-tap scans and malicious site blocking. This proactive approach is excellent for users concerned about cybersecurity. Meanwhile, the TP-Link Deco X55 Pro includes TP-Link HomeShield, which provides essential security features such as security scans and IoT device identification, but it is not as comprehensive as the ASUS offering. If security is a priority, the ASUS router provides a more robust solution.
User Experience and Setup

Users can set up and manage their network in minutes, enhancing the overall experience. The ASUS RT-BE86U also offers advanced management features but may require a bit more technical knowledge to fully utilize its capabilities. For those who prefer a hassle-free setup, the TP-Link Deco X55 Pro presents an easier option.
Price Comparison
At $219.99, the ASUS RT-BE86U costs $20 more than the TP-Link Deco X55 Pro, which is priced at $199.99. This price difference reflects the advanced features and higher performance of the ASUS router, particularly in speed and wired connectivity. While the ASUS offers superior capabilities for power users, the TP-Link's lower price point makes it an attractive choice for users seeking solid performance without breaking the bank. If cost is a significant factor, the TP-Link Deco X55 Pro presents a compelling value.
Which should you buy?
Choosing between the ASUS RT-BE86U and the TP-Link Deco X55 Pro ultimately depends on your specific needs. If high-speed performance, advanced connectivity options, and robust security are your main priorities, the ASUS router is the clear winner. However, if you need extensive coverage for multiple devices at a lower price point, the TP-Link Deco X55 Pro is an excellent option. Assess your usage habits, home size, and budget to make the best decision for your networking needs.
