TP-Link’s Archer AX21 is an AX1800 dual-band Wi-Fi 6 router with OFDMA, beamforming, Gigabit ports, EasyMesh and app setup. A solid budget upgrade for apartments and mid-size homes; it needs a separate modem and lacks a 6 GHz band. It works with the major US internet providers.
Description
The TP-Link Archer AX21 is an AX1800 dual-band Wi-Fi 6 router for people whose internet provider’s box, or an ageing Wi-Fi 5 router, struggles once every phone, laptop and smart plug in the house is online. It connects to your existing modem rather than replacing it.
Breaking down the Archer AX21
TP-Link rates it at up to 1,200 Mbps on 5 GHz and 574 Mbps on 2.4 GHz. OFDMA helps it juggle many devices at once, four high-gain antennas use beamforming, and there are Gigabit Ethernet ports for desktops, TVs and consoles. It supports EasyMesh, the Tether app, Alexa, and OpenVPN/PPTP VPN servers.
One thing to watch: needs a separate modem
You need a separate modem or an ISP gateway in bridge mode. Compare your plan speed with the router’s real-world capability; for plans near 1 Gbps, a higher-tier or mesh model may serve better.
Putting the Archer AX21 to work
It suits apartments and small-to-mid-size homes with video calls, streaming and gaming happening at the same time. If coverage later falls short, an EasyMesh-compatible extender can be added rather than replacing the router.
There is no 6 GHz band, so it is Wi-Fi 6 rather than 6E or Wi-Fi 7.
