Performance: Speed and Efficiency on a Budget
The TP-Link Archer AX21 leverages Wi-Fi 6 to provide 1.8 Gbps speeds, with 1200 Mbps on the 5 GHz band for high-speed tasks like 4K streaming and online gaming, and 574 Mbps on the 2.4 GHz band for longer-range connections. While it doesn’t match the 3 Gbps of the TP-Link Archer AX55, its performance is more than adequate for most households.
OFDMA and MU-MIMO technologies allow the router to handle multiple devices simultaneously, reducing latency during peak usage. This makes it ideal for homes with smart TVs, gaming consoles, and IoT devices. Its dual-band setup ensures efficient bandwidth allocation, delivering smooth performance for video calls and downloads.

Coverage: Reliable Wi-Fi for Medium Homes
The Archer AX21 uses four high-gain antennas and Beamforming to focus Wi-Fi signals, providing reliable coverage for medium-sized homes or apartments. It effectively eliminates dead zones in spaces with moderate layouts, though it may require extenders for larger homes with complex structures.
Its EasyMesh compatibility allows seamless integration with TP-Link extenders, creating a mesh network for broader coverage. Compared to the Amazon eero 6’s 1,500 sq. ft. coverage, the AX21 offers similar range but lacks built-in mesh functionality without add-ons.

Smart Features: Alexa and VPN Support
The TP-Link Archer AX21 shines with smart features typically found in pricier routers. Its Alexa compatibility enables voice control for tasks like enabling guest Wi-Fi or pausing internet access. The VPN server (supporting OpenVPN and PPTP) ensures secure remote access, ideal for home offices or privacy-conscious users.
Unlike the Amazon eero 6, which includes a Zigbee hub for smart home devices, the AX21 focuses on core networking features. However, its TP-Link Tether app offers intuitive network management, including device prioritization and guest network setup.

Setup and Usability: User-Friendly Experience
Setting up the Archer AX21 is straightforward with the TP-Link Tether app, which guides users through installation and provides tools for network monitoring, firmware updates, and parental controls. The router’s compact design fits easily into any home, and its fanless cooling ensures quiet, reliable operation.
Compatible with all major ISPs like Comcast, AT&T, and Spectrum (modem required), the AX21 is versatile for various internet plans. Compared to the NETGEAR Nighthawk RS90’s more complex setup, the AX21 is ideal for users seeking simplicity.

Security: Basic Protection for Your Network
The Archer AX21 offers basic security features, including WPA3 encryption for secure connections and firmware updates to patch vulnerabilities. While it lacks the advanced TP-Link HomeShield suite found on the Archer AX55, its VPN support adds a layer of security for remote access.
For users needing robust cybersecurity, the NETGEAR Nighthawk RS90’s NETGEAR Armor provides superior protection, as detailed in “TP-Link Archer AX55 vs. NETGEAR Nighthawk RS90: Wi-Fi 6 vs. Wi-Fi 7 Showdown”. Still, the AX21’s free security features are sufficient for most households, with options to integrate third-party tools for added protection.

- Budget-conscious users seeking Wi-Fi 6 performance without breaking the bank.
- Small to medium homes needing reliable coverage for streaming and gaming.
- Smart home users who value Alexa compatibility and VPN support.
