TP-Link Archer AX21 Performance

The AX21 delivers fast speeds and great range, making it perfect for gaming and streaming. Four 1GB Ethernet ports provide high-speed network connectivity.

The AX21s 4 external Antennas deliver very good range and stability as a result of MU-MIMO, Beamforming, and OFDMA technology so it can reach every corner of your home without losing signal. Connectivity The AX21 has USB 3.0 ports for 5Gbps data transfer, so you can connect more devices to your network. Security The Archer AX21 uses multiple technologies such as an SPI Firewall, Access Controls, WPA2, WPA3, and WPA/WPA2-Enterprise to ensure a secure and reliable connection between your network devices and the Internet.

In testing the AX21 was slightly faster than other budget Wi-Fi 6 routers such as the Netgear R6700AX and Asus -RT-AX55. Speeds were roughly the same for all three routers throughout a 1,200-square-foot home. Download speeds and latency (ping time) were roughly the same for all three routers. In terms of performance the Netgear R6700AX, Asus RT-AX55, and the Archer AX21 offer no competitive advantages against each other. From here it’s just a matter of personal, preference, availability, and price.
