The TP-Link Archer AX21 V4 is a powerful and affordable Wi-Fi 6 router that delivers impressive performance for home users who need fast and reliable internet across multiple devices. Whether you’re streaming, gaming, or working from home, this router offers excellent value for its price point.
Performance & Speed
With support for Wi-Fi 6 (802.11ax), the Archer AX21 provides up to 1.8 Gbps total bandwidth — split as 1200 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. This translates to faster downloads, smoother 4K streaming, and low-latency online gaming. The router handles multiple devices simultaneously thanks to OFDMA technology, which efficiently distributes data to reduce network congestion.
Coverage & Reliability
The router features four high-gain antennas, Beamforming technology, and an advanced front-end module (FEM) chipset, all of which work together to provide strong, reliable coverage throughout medium to large homes. Devices far from the router still receive a stable connection, making it a solid choice for households with dead zones or multiple floors.
Ease of Use & Smart Features
Setup is user-friendly, with a straightforward app interface and easy integration with Alexa, qualifying it as a “Certified for Humans” device. It also supports EasyMesh, allowing for expandable mesh networking if more coverage is needed in the future.
Security & VPN
For users concerned with privacy and remote access, the Archer AX21 V4 includes support for both OpenVPN and PPTP VPN servers, a feature rarely found in routers at this price level.
Compatibility
The router is compatible with all major ISPs, including Comcast, AT&T, Verizon, Spectrum, and more. Note that a separate modem is required if your ISP doesn’t provide one built-in.
