TP-Link Archer TX20UH AX1800 High Gain Wi-Fi 6 USB Adapter
The TP-Link Archer TX20UH is an AX1800 dual-band Wi-Fi 6 USB adapter that upgrades any desktop or laptop to the latest wireless standard without opening the case. With high-gain adjustable antennas, Beamforming technology, and a 1.2-metre USB 3.0 cable for flexible positioning, it delivers fast, stable Wi-Fi 6 connectivity from wherever you need it in your home or office — ideal for Australians looking to get more from their Wi-Fi 6 router without replacing their PC.
Key Features
-
AX1800 Wi-Fi 6 Speed — Up to 1201Mbps on 5GHz and 574Mbps on 2.4GHz for combined wireless throughput of 1800Mbps — significantly faster than Wi-Fi 5 adapters.
-
High-Gain Adjustable Antennas — Multi-angle adjustable antennas extend Wi-Fi range and improve signal reception, particularly in larger homes or through walls and floors.
-
Beamforming Technology — Concentrates Wi-Fi signals towards your router for a stronger, more reliable connection from greater distances.
-
OFDMA & MU-MIMO — Reduces latency and improves efficiency in multi-device environments — particularly beneficial for online gaming and video calls.
-
USB 3.0 with 1.2m Cable — SuperSpeed USB 3.0 (up to 4.8Gbps transfer) with a 1.2-metre cable for flexible placement away from the PC — position the adapter for the best possible signal.
-
Dual-Band Wi-Fi — Switch between 2.4GHz for range and 5GHz for speed depending on your environment and use case.
-
WPA3 Security — Latest Wi-Fi security standard provides stronger, individualised encryption to protect your wireless connection.
-
Backward Compatible — Supports 802.11ac/a/b/g/n for use with older Wi-Fi 5 and Wi-Fi 4 routers.
-
Plug & Play — No tools or case opening required; simply plug into any available USB port and install the driver.
Use Cases
- Desktop PCs without a built-in wireless card needing Wi-Fi 6 connectivity
- Laptops with a weak or failed internal Wi-Fi card requiring an external upgrade
- Home office setups where the PC is far from the router and signal strength is poor
- Gaming PCs requiring lower latency wireless without running an Ethernet cable
- Upgrading from Wi-Fi 5 (AC) to Wi-Fi 6 (AX) to match a new router without replacing the PC

Frequently Asked Questions
Does the Archer TX20UH work with Wi-Fi 5 (AC) routers?
Yes. The TX20UH is backward compatible with 802.11ac (Wi-Fi 5), 802.11n (Wi-Fi 4), and older standards. You’ll still benefit from the high-gain antennas and improved range, though the full AX1800 Wi-Fi 6 speeds require a Wi-Fi 6 router.
Can I use this adapter with a laptop?
Yes. The TX20UH connects via USB 3.0 and works with any laptop or desktop that has an available USB port. The 1.2-metre cable allows you to position the adapter and its antennas for the best possible signal, rather than being limited to the USB port location.
Why is the USB cable useful for a Wi-Fi adapter?
Most USB Wi-Fi adapters plug directly into the back of a desktop PC, where the case itself can block or degrade the signal. The TX20UH’s 1.2-metre cable lets you place the adapter on your desk or at a height where the antennas have a clear line of sight to your router — significantly improving signal strength and stability.
Does it support 160MHz channel width?
The TX20UH supports up to 80MHz channel width on the 5GHz band for AX1800 operation. For 160MHz support, consider the Archer TX55E PCIe adapter, which uses an Intel Wi-Fi 6 chipset with 160MHz capability.
What operating systems are supported?
The Archer TX20UH supports Windows 11, 10, 8.1, and 7, as well as macOS 10.9 through 10.15. Linux is not officially supported.
Will this reduce latency for online gaming?
Yes. The TX20UH’s OFDMA technology reduces network latency compared to Wi-Fi 5, and the high-gain antennas with Beamforming provide a more stable connection — both of which contribute to a more responsive gaming experience, provided your router also supports Wi-Fi 6.
