How to install StarTech.com USB C to Dual Gigabit Ethernet Adapter

• 1) Connect the USB-C end of the adapter to a free USB-C port on your computer. If your computer provides power through USB-C, the device will draw power from the host without needing an external power adaptor.
• 2) Attach two Ethernet cables to the RJ-45 ports. Use Cat5e or Cat6 cables for best performance to your network switch, router, or modem.
• 3) If you need to use a USB peripheral, plug it into the USB 3.0 Type-A port on the adapter. This allows you to run a keyboard, flash drive, webcam, or other USB device while keeping network connections intact.
• 4) Power up your system (if required) and navigate to your operating system’s network settings. The two Ethernet interfaces should appear as separate adapters labeled accordingly (for example, “Ethernet 1” and “Ethernet 2”). In most cases, DHCP will assign IP addresses automatically.
• 5) If prompted by your OS to install drivers, follow the on-screen instructions or visit StarTech support for the latest driver packages. Many modern Windows, macOS, and Linux distributions provide basic driver support for USB Ethernet devices, ensuring a smooth, driverless experience on compatible systems.
