## At a glance

- Dual-band Wi-Fi 6 with listed maximum rates of 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz.
- Multi-angle high-gain antennas and Beamforming are intended to improve reception by directing signals towards the router.
- A 1.2-metre USB 3.0 cable allows more choice in where the adapter sits on a desk.
- OFDMA and MU-MIMO are specified for use with a compatible router.
- WPA3 is listed for wireless security. The listing says Windows 10/11, though a separate compatibility field gives Windows 11 as the minimum.

## Pros

- The extension cable and adjustable antennas provide placement flexibility instead of requiring the adapter to sit directly at the computer's USB port.
- Two Wi-Fi bands offer a choice between the listed 5 GHz and 2.4 GHz connections.
- The listing specifies WPA3, OFDMA and MU-MIMO for compatible setups.

## Cons

- The stated 1800 Mbps is a combined headline rate, not a guaranteed single-device internet speed. Actual performance depends on the network and environment.

## Before you buy

- The listing gives Windows 10/11 in its feature text but lists Windows 11 as the minimum required version, so Windows 10 compatibility is not consistently stated. Its 1800 Mbps headline is paired with separate 1201 Mbps and 574 Mbps band rates, and the page separately claims USB 3.0 transfers up to 4.8Gbps. Treat these as distinct claims, not a guaranteed real-world connection speed. Customer feedback also reports varied compatibility, reception and speed.

## In the box

- Archer TX20UH (Included)

## A good fit for

- Desktop PC users who need a USB Wi-Fi adapter and can confirm compatibility with their Windows version.
- Buyers who want a cable and adjustable antennas to position a wireless adapter away from a crowded USB port.

## Less suited to

- Users who need assured compatibility with an operating system other than Windows.
- Buyers who require a guaranteed Wi-Fi speed, stable reception at a particular distance or confirmed performance with their router.

## Customer feedback

Customer feedback praises ease of installation and compact size, while reports on signal strength, connectivity, operating-system compatibility and speed are mixed. That matters for a USB adapter whose placement and Windows support affect practical use. The listed Wi-Fi rates and antenna features are manufacturer claims, not proof of consistent reception or compatibility in every setup.
- Positive themes: Customers describe it as easy to install and appreciate its compact size.
- Mixed feedback: Customers report both strong reception and weak signals or disconnections.
- Mixed feedback: Compatibility experiences vary, and reported speeds differ.

## Frequently asked questions

### Does the Archer TX20UH support Windows 10?
The listing's feature text says Windows 10/11, but a separate system requirement names Windows 11 as the minimum. Confirm Windows 10 compatibility for the selected product listing before buying.
### What does AX1800 mean here?
The page lists up to 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz, and also states a combined 1800 Mbps headline. These are listed maximums, not a promise of internet speed.
### Can the adapter be placed away from the PC?
The listing describes a 1.2-metre USB 3.0 extension cable and multi-angle antennas, giving flexibility to position the adapter within the cable's reach.
### Will it work with my router?
The listing describes a Wi-Fi 6 adapter with OFDMA and MU-MIMO, but says those features depend on a compatible router. Check your router and operating system compatibility.
