USB-C Gigabit Ethernet Adapter for Laptops

The j5create JCE133G adds a single RJ-45 port to any USB-C equipped Ultrabook or MacBook. It targets users who need a wired 10/100/1000 BASE-T connection instead of relying on wireless. The silver adapter draws power directly from the host port and requires no external supply.

Driver-Free Setup With Wake-on-LAN Support

Installation is a simple plug-and-play action on systems supporting Microsoft NDIS 5 and 6 checksum offload engines. The package includes a quick installation guide but no separate driver media. Compatibility issues may arise on older hosts limited to USB 1.1 speeds where Gigabit throughput cannot be sustained.

Steady Throughput With Energy Efficient Ethernet

Under continuous load the adapter maintains line-rate performance using IEEE 802.3az-2010 Energy Efficient Ethernet to reduce idle power. Segmentation task-offload for large send v1 and v2 lowers CPU utilisation during long transfers. The USB 3.1 Gen 1 interface prevents the bottlenecks seen on USB 2.0 links during sustained traffic.

Questions about this item

How can I verify the JCE133G is delivering the full 1000 Mbps link after I plug it in?

Check the network adapter status in your OS; it should show a 1 Gbps connection and the adapter's LED will indicate an active Gigabit link.

Does the package include any cables or only the adapter and the Quick Installation Guide?

The box contains the USB-C to Gigabit Ethernet adapter and a Quick Installation Guide; an Ethernet patch cable is not included.

My laptop has USB 2.0 ports — will the JCE133G still work, or do I need USB 3.1 Gen1 for Gigabit speeds?

The adapter is backwards compatible with USB 2.0 and 1.1, though maximum throughput will be limited to the USB 2.0 bandwidth.
