Overview

The ASUS USB-AX56 is a Wi-Fi 6 USB adapter supporting dual-band 2.4 and 5 GHz connections. It connects via USB 3.2 Gen1 and uses two external antennas to pick up a signal.

Who it suits

This is suited to desktop or laptop users who need to add Wi-Fi 6 connectivity to a device that lacks it or has an outdated wireless card. It fits setups where a USB connection is more practical than opening a case to install an internal card.

Reasons to consider it

It supports Wi-Fi 6 on both 2.4 and 5 GHz bands, which covers the two most commonly used frequency ranges. USB 3.2 Gen1 provides a fast connection between the adapter and host device, and the two external antennas are provided to assist signal reception.

Limitations and compatibility checks

There is no 6 GHz band support, so this adapter is limited to the older dual-band Wi-Fi 6 standard rather than Wi-Fi 6E. It has no Ethernet ports and no wired backhaul option, since it is a USB adapter rather than a router or extender.
