TP-Link Archer TX20U Nano | AX1800 Nano Wi-Fi 6 Wireless USB Adapter
The TP-Link Archer TX20U Nano is a tiny dual-band Wi-Fi 6 USB adapter that adds wireless internet to a Windows 11 or 10 computer, or upgrades an older built-in Wi-Fi card. It is rated AX1800, with up to 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz, and measures only 26.8 x 15.7 x 7.5 mm.

Dual-band Wi-Fi 6 speed: The adapter supports 802.11ax on both bands, so your PC can connect to the 5 GHz band for higher speeds near the router or to the 2.4 GHz band for longer range. With a Wi-Fi 6 router you get the full AX1800 link rate; it also works with older Wi-Fi 5 and Wi-Fi 4 routers at their speeds.

OFDMA and MU-MIMO: When used with a compatible router, OFDMA and MU-MIMO let your PC share the Wi-Fi more efficiently with other devices, which helps reduce lag in video calls, streaming and games.

WPA3 security: Support for the latest WPA3 encryption gives stronger password protection on your home Wi-Fi, alongside WPA/WPA2 for older networks.

Nano size: At 26.8 x 15.7 x 7.5 mm it is small enough to leave plugged into a laptop's USB port when you travel, without sticking out.
Easy setup: The driver is pre-loaded on the adapter itself. Plug it in and install the driver from the adapter, without needing a CD or a separate download.

Who it's for / Works with
Desktop PCs and laptops running Windows 11 or Windows 10 that need Wi-Fi or a faster Wi-Fi connection.
Good to know
The adapter uses a USB 2.0 interface. TP-Link lists Windows 11 and 10 as the supported operating systems; macOS and Linux are not listed. The speeds above are maximum wireless link rates; real speeds depend on your router, distance and interference.
