Compact dual-band adapter for Windows PCs

The Archer T2UB Nano adds AC600 Wi-Fi and Bluetooth 4.2 to desktops or laptops through a USB 2.0 port. It supports Windows 11 down to Windows 7 for Wi-Fi and Windows 11 down to Windows 7 for Bluetooth, making it a simple upgrade for older systems that lack built-in wireless.

Steady throughput on both bands under load

The adapter delivers up to 433 Mbps on the 5 GHz band and 200 Mbps on the 2.4 GHz band, with 256QAM raising the 2.4 GHz rate from 150 Mbps by 33 percent. Dual-band operation lets the connection shift to the clearer 5 GHz channel for HD streaming or gaming while keeping 2.4 GHz available for legacy devices and wider coverage.

Low-profile design runs cool and quiet

The nano form factor sits almost flush with the USB port, drawing minimal power from the bus and producing no audible noise. Its small footprint avoids blocking adjacent ports and stays in place during transport, while WPA3 encryption secures the link without adding processing overhead.
