USB-C 10/100 Mbps Network Adapter

The EN-Labs CU2RJ45FAST adds a wired Ethernet port to any device with a USB-C connector. It uses the RTL8152 chipset and a USB 2.0 interface to deliver 10/100 Mbps Fast Ethernet over a 480 Mbps bus. No driver is required for Windows 8 or Mac OS X 10.9 and newer. The adapter supports Wake-on-LAN and automatic speed switching between 10 Mbps and 100 Mbps.

Travelers and legacy hardware users

This adapter suits owners of MacBooks, Chromebooks, tablets or older laptops that lack a built-in RJ45 port. It works with Windows 2000 through 8.1, Linux, Mac OS 10.6, Android 2.1 through 4.0 and WinCE 5.0 and 6.0. Buyers who need Gigabit throughput should look elsewhere. Devices without a USB-C socket cannot use this adapter directly.

USB 2.0 bandwidth ceiling

The USB 2.0 host interface limits maximum throughput to 480 Mbps, which caps real-world Ethernet performance at 100 Mbps. This makes the adapter a direct replacement for a failed 10/100 Mbps onboard port or a secondary low-bandwidth interface. It will not saturate a Gigabit or faster network link.

Questions about this item

Does my device need a USB-C port to use this adapter?

Yes, the adapter has a USB Type-C male connector that plugs directly into a USB-C port on your computer or tablet.

Will this adapter work on a 10 Mbps network I still use?

It auto-senses and switches between 10 Mbps and 100 Mbps networks, so it works with older 10 Mbps infrastructure.

How can I confirm the adapter is running at 100 Mbps after I plug it in?

Check the network status in your operating system; it will show the link speed as 100 Mbps when connected to a Fast Ethernet switch or router.
