The TP-Link Archer AX21 is a dual-band WiFi 6 router engineered for households seeking a significant upgrade from older networking equipment. It delivers 1.8 Gbps total bandwidth (1200 Mbps on 5 GHz, 574 Mbps on 2.4 GHz) and is compatible with all major internet service providers. This router is ideal for families with multiple connected devices, gamers, streamers, and anyone frustrated with slow or unreliable WiFi performance.
The standout feature of this router is its exceptional range and coverage capability. Four high-gain antennas combined with advanced beamforming technology focus signal strength toward your devices, ensuring strong connections even in distant rooms or areas with obstacles. WiFi 6 technology with OFDMA support allows the router to communicate with multiple devices simultaneously, eliminating the congestion and slowdowns common with older routers handling heavy network traffic.
Setup is remarkably straightforward, with users reporting successful connections in just minutes using either the mobile app or web browser interface. The router features a modern, compact black design that fits discreetly in most home environments. Built-in security includes WPA3 protocol support and compliance with the CISA Secure-by-Design pledge, giving you confidence in your network's protection. Additional features include VPN server support, parental controls, and Alexa voice integration for hands-free management.
The primary consideration is that this router requires a separate modem for internet connectivity, which may mean an additional purchase if you don't already have one. The phone app can occasionally present setup challenges, though the web browser interface provides a more reliable alternative. As a dual-band router, it does not support the 6 GHz band available on premium WiFi 6E models.

Buying Guide: What to Look for in a Dual WAN Router
WAN Port Configuration and Flexibility
Not all dual WAN routers are created equal. Some offer dedicated WAN ports, while others allow you to convert LAN ports into WAN ports. The TP-Link ER605 features one dedicated Gigabit WAN port plus two configurable WAN/LAN ports, giving you a total of three possible WAN connections. This flexibility lets you mix fiber, cable, or DSL as your primary connections.
For business environments that need reliable internet for multiple users, checking out the top business routers can provide additional perspective on port layouts and throughput.
Load Balancing vs. Failover Modes
Dual WAN routers typically support two modes: load balancing spreads traffic across both connections to maximize bandwidth, while failover switches to the backup WAN only when the primary goes down. The TP-Link ER605 supports both, letting you choose based on your needs. For example, load balancing is ideal for offices with many users streaming or uploading, while failover is better for critical applications like payment processing.
VPN Throughput and Security Features
If you connect remote employees or branch offices, VPN performance matters. The ER605 supports up to 20 IPsec, 16 OpenVPN, 16 L2TP, and 16 PPTP VPN tunnels. Its SPI firewall and DoS defense protect your network from threats. This router is built for secure, encrypted connections without sacrificing speed.
For those who want deeper customization, the top OpenWrt routers for custom networking guide covers options with open-source firmware.
Build Quality and Form Factor
Designed for rack-mountable or desktop use, the ER605 is a compact metal box that fits well in a network closet. Its five Gigabit ports provide wired connectivity for up to five devices directly. The lack of Wi-Fi means you must pair it with a wireless access point, but that also reduces interference and heat.
Final Thoughts
If you need a dependable dual WAN router that offers flexible WAN configuration, strong VPN support, and enterprise-grade security at a reasonable price, the TP-Link ER605, Wired Gigabit VPN Router is our top recommendation. It handles failover and load balancing effectively, and its three WAN ports give you room to grow. For a pure wired solution that pairs well with any access point, this router delivers exactly what a dual WAN setup demands.
Frequently Asked Questions
What is a dual WAN router and why do I need one?
A dual WAN router lets you connect two internet sources simultaneously. This provides automatic failover if one connection goes down, or load balancing to combine bandwidth. It is ideal for businesses that cannot afford downtime or for heavy internet users who want extra speed.
