The TP-Link Archer TX20UH brings dual-band Wi-Fi 6 to a desktop or laptop that is stuck on older wireless, without opening the case. It delivers up to 1201 Mbps on 5 GHz plus 574 Mbps on 2.4 GHz (AX1800 class), and its two multi-angle high-gain antennas work with Beamforming to focus signal towards your router, which helps in a study or bedroom far from the router or behind a few brick walls, a common situation in South African homes. The adapter connects over SuperSpeed USB 3.0, and it ships with a USB 3.0 cradle on a 1.2 m cable, so you can stand it on the desk up and away from the back of the PC for better reception. WPA3 is supported alongside WPA/WPA2, and TP-Link lists Windows 10 and 11 support. It suits gaming, video calls and large downloads where a tiny nano adapter struggles. In the box: the Archer TX20UH adapter, the USB 3.0 cradle and a quick installation guide.
