A ThinkPad USB-to-Ethernet adapter provides a fast, stable wired internet connection for laptops that lack an onboard Ethernet port. Most modern adapters are plug-and-play, meaning they work automatically once connected. For older models or specific operating systems, a driver installation might be needed.
Specifications
Key Features
Connect the adapter to your ThinkPad. Plug the USB end of the adapter into an available USB port on your laptop.
Connect the Ethernet cable. Plug one end of a standard Ethernet cable into your network source (router, modem, or network switch) and the other end into the RJ45 port on the adapter.
Wait for automatic setup. For most modern Windows (10/11) and macOS systems, your computer will automatically recognize the new hardware and install the necessary drivers. You may see a notification confirming that a new wired network connection has been set up.
Verify your connection. You can check that your device is using the wired connection:
On Windows: Hover your cursor over the network icon in the taskbar. It should show the Ethernet network name with "Connected" or "Internet access" underneath.
On macOS: Go to System Settings > Network. You should see a new "USB Ethernet" or "Ethernet" entry with a green indicator.
Disable Wi-Fi (optional). To ensure your system is prioritizing the faster, more stable wired connection, you can temporarily turn off your Wi-Fi.
