How to use

Connect the adapter's USB-C plug to a free USB-C port on your computer or tablet, then attach a standard Ethernet cable to the RJ45 port and to your network outlet, router or switch.

After connection, configure network settings via your operating system's network control panel if a static IP or specific DNS is required.

Usage recommendations

For best performance, use a Cat5e or higher Ethernet cable and ensure the host device's USB-C port supports data transfer. When using in professional or high-traffic environments, verify driver availability for your operating system and test connection speed after installation to confirm Gigabit operation.
