How to use

Insert the adapter's USB-C plug into a compatible USB-C port on your laptop, tablet or other device. Connect an Ethernet cable from a router, switch or wall outlet to the adapter's Ethernet port. The device should detect the wired connection automatically on operating systems that include native driver support; if required, install the appropriate driver provided by the device manufacturer. Confirm network settings on your system (such as DHCP or static IP) and verify link/activity LEDs on the adapter or connected network equipment to ensure a successful connection.

Recommendations

Use a quality shielded Ethernet cable for the best signal integrity and avoid excessive bending near the connectors. For prolonged use, keep the adapter in a ventilated area and avoid covering it with other equipment to prevent heat build-up. If you experience connectivity issues, try a different USB-C port or update the host device network drivers.
