Frequently Asked Questions
Do I need a Wi-Fi 6 router to use the Archer TX20U?
No. The Archer TX20U is backward compatible with 802.11a/b/g/n/ac routers. However, to take full advantage of Wi-Fi 6 features such as OFDMA and improved throughput, you will need a Wi-Fi 6 router or access point.
Does the Archer TX20U work on macOS?
The Archer TX20U officially supports Windows 7 through Windows 11. macOS is not officially supported. Mac users should look for an adapter with confirmed macOS driver support.
Is a USB extension cable included?
Yes. A USB 3.0 extension cable is included in the box, allowing you to position the adapter away from your PC for better signal reception if needed.
What is the difference between the TX20U and the T2UB Nano?
The Archer TX20U supports Wi-Fi 6 (AX1800) with a faster 5GHz speed of 1201Mbps and includes an external antenna for better range. The T2UB Nano is an AC600 Wi-Fi 5 adapter with a nano form factor and integrated Bluetooth 4.2, better suited for travel or minimal setups where size is the priority.
Does the TX20U include Bluetooth?
No. The Archer TX20U is a Wi-Fi-only adapter. If you also need Bluetooth, consider the Archer T2UB Nano (Bluetooth 4.2) or the Archer TXE72E PCIe adapter (Bluetooth 5.2).
Do I need to install drivers?
Yes. Drivers are required and can be downloaded from the TP-Link AU website. Installation is straightforward and typically takes only a few minutes.
