Works great! Fast gigabit ethernet speeds on laptops, MS Surface Pro, and iPhone!
I bought this USB-C to Ethernet Adapter as my Microsoft Surface Pro 11 does not have an Ethernet port and sometimes WiFi connections are pretty bad. At home, I have decent WiFi speeds, in excess of 500Mbps. When I connected this to my Surface Pro, I only got 200Mbps! Looking online, I saw the following fix: Adjust Ethernet Adapter Settings In Device Manager, right-click the Ethernet adapter → Properties → Advanced tab: Set Speed & Duplex to 1.0 Gbps Full Duplex (prevents auto-negotiation failures). Disable power-saving features like Energy Efficient Ethernet or Green Ethernet. Under the Power Management tab, disable Allow the computer to turn off this device to save power. After dong this and restarting the Surface Pro, I saw ethernet speeds in excess of 950Mbps! So the adapter works great as long as your computer is properly configured. I tried using the adapter on my iPhone 17 Pro Max and it also worked great, giving me gigabit ethernet on my iPhone (see attached image)! I have not tried charging my laptop through the 100W charging port. Read more
