How to use
Insert the adapter into an available USB 3.0 port on the computer and connect a network cable from the adapter's RJ45 port to the Ethernet switch, router or wall port. The adapter typically installs using the host operating system's built-in drivers or standard adapter drivers; follow on-screen prompts if additional drivers are required. Once connected, verify network settings in the operating system and test the connection speed to confirm Gigabit performance where supported by the network infrastructure.
Usage recommendations
For best results, use a USB 3.0 (or higher) port and a Cat5e or Cat6 Ethernet cable to reach Gigabit speeds. When performing system imaging or large file transfers, ensure the network switch or router and the remote device also support Gigabit Ethernet. Store the adapter in a dry location and avoid excessive bending of the cable near connection points.
