USB 3.0 WiFi 6 adapter for desktop PCs

This TP-Link Archer TX21UH adds AX1800 WiFi 6 to any desktop with a free USB 3.0 port. It targets users who want wireless connectivity without opening the case or installing a PCIe card. The dual-band design delivers up to 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz.

Plug-and-play upgrade with adjustable antennas

Insert the adapter into a USB 3.0 socket for up to 10x the throughput of USB 2.0, then position the multi-angle high-gain antennas for best reception. Beamforming focuses the signal toward the router, reducing the need for a centrally located PC. Windows 10 and 11 support is built in.

OFDMA and MU-MIMO keep latency low under load

When paired with a compatible router, OFDMA lets your PC receive data simultaneously with other devices on the same stream. MU-MIMO allows the router to serve multiple clients at once, so sustained streams, uploads and gameplay stay responsive even when the network is busy. WPA3 encryption secures the link.

Questions about this item

Does the 1201 Mbps 5 GHz link hold steady when the USB 3.0 bus is saturated?

The adapter tops out at 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz; USB 3.0 provides up to 10× the throughput of USB 2.0, so the wireless link is the practical ceiling under sustained load.

How hot or loud does the Archer TX21UH get during all-day use?

The device has no fan and draws power only from the USB 3.0 port, so it runs silently and stays at a low temperature during continuous operation.

What must my PC already have for this adapter to work?

A free USB 3.0 port and Windows 10 or Windows 11 are required; the adapter adds dual-band Wi-Fi 6 with high-gain antennas and Beamforming to any compatible desktop.
