Tenda U3 WiFi Dongle 300Mbps USB Wireless Adapter, 2.4GHz, Linux, U3 N300
The Tenda U3 (N300) is a compact USB WiFi adapter offering up to 300 Mbps wireless‑N speeds over the 2.4 GHz band. It supports common standards (802.11b/g/n), Security protocols (WPA/WPA2 etc.), has a ‘Soft AP’ mode (can act as hotspot), works via USB 2.0, and is compatible with Windows, macOS, Linux, Raspberry Pi etc. It’s designed for simple wireless connectivity, ideal for adding WiFi to desktops, older laptops, or single‑board computers.
