The adapter complies with the USB 2.0 specification, includes LEDs indicating USB and network status, and is supplied with a short 0.115 m cable. Its small size (65 × 22 × 11 mm) and white colour make it suitable for desktop or mobile setups.

Advantages

The adapter provides stable wired Ethernet where onboard ports are unavailable or damaged. Using the AX88772C chipset ensures compatibility with a wide range of operating systems, including legacy Windows and macOS versions. The plug-and-play USB A connector and automatic speed negotiation simplify installation and reduce configuration time. Integrated LEDs give immediate visual feedback on USB and network activity.

How to use

Connect the USB A male plug to an available USB 2.0 port on your computer and insert an Ethernet cable into the RJ45 female socket. The adapter negotiates network speed automatically; install drivers if your operating system requires them (drivers available for Windows 98SE/ME/2000/XP/7/8/8.1 and Mac OS 5.0). Verify the LEDs to confirm USB power and network link/activity before using network services.

Recommendations

For reliable performance, use a quality Cat5e or Cat6 Ethernet cable and connect the adapter to a full-speed USB 2.0 port. If the device is used with older operating systems, ensure the correct driver version is installed. Avoid strain on the short cable and keep the adapter dry and away from excessive heat.
