Kensington CA1100E — CA1100E USB-C to Gigabit Ethernet Adapter
Gigabit EthernetUSB-C / Thunderbolt 3Plug and playBusiness grade
The Kensington CA1100E is an USB-C to Gigabit Ethernet adapter that adds a wired Gigabit Ethernet port to a laptop, desktop PC, tablet or thin client through its USB-C port. Kensington specifies plug-and-play operation with the drivers already built into Windows, macOS and Chrome OS. It connects at 10/100/1000 Mbps. It draws its power from the USB port, so there is no separate power supply to carry. A cable connection is the dependable answer when Wi-Fi is weak, crowded or not allowed, when a slim laptop has no network socket, or when backups, large downloads and video calls need a steady, low-latency link.
Compatibility — check before buying:
Check the port: the adapter has a USB-C plug and does not fit USB-A ports; any USB-C data port works, including Thunderbolt 3/4 and USB4 ports. It links at up to 1 Gbps with any standard switch or router port, and Cat5e cable or better is enough. Operating systems listed by Kensington: Windows 8.1 and later, macOS 10.10 and later, Chrome OS 44 and later. Not sure it suits your laptop, dock or switch? Tell us the model and we check it.

Frequently Asked Questions
Do I need to install a driver?
No. Kensington specifies plug and play with the drivers built into Windows 8.1+, macOS 10.10+ and Chrome OS 44+.
Is it faster than Wi-Fi?
A wired Gigabit link gives up to 1 Gbps with steadier latency than most Wi-Fi connections — that is what video calls, remote desktop and large transfers benefit from. Your internet speed still depends on your connection.
Can I use it on a USB-A port?
No, it has a USB-C plug only. For USB-A computers choose a USB-A version.
Does it work through a dock or USB hub?
Usually yes — it is a standard USB network device. For full speed the hub or dock port must be USB 3.x, and bus-powered hubs should have enough power for all connected devices.
