The Archer AX21 is an AX1800 dual-band Wi-Fi 6 router, a practical pick when a customer needs more speed and capacity than an ISP router gives. Wi-Fi 6 runs on both bands, up to 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz.

Built for homes with many connected devices

Wi-Fi 6 on both bands, OFDMA and four streams let the router serve a lot of phones, TVs and smart devices at once. Four fixed high-performance antennas with beamforming and a high-power front-end module cover a three-bedroom home. OneMesh support lets you add compatible TP-Link extenders under one network name. It runs as a router or an access point, includes a VPN server, and supports WPA3 with guest networks on both bands.
