Description

Lenovo 4X90S91831 USB-C to Ethernet System Cable

Overview

The Lenovo 4X90S91831 is a USB-C male to Ethernet female system cable in black, designed to bridge USB-C-equipped systems to wired Ethernet networks. This cable addresses the common scenario where a Lenovo system lacks a native RJ-45 port — providing a direct, physical network connection without relying on wireless. The 4X90S91831 is a factory-new, genuine Lenovo system accessory sourced direct from the manufacturer.

Compatibility

Designed as a Lenovo system cable, the 4X90S91831 is intended for use with Lenovo devices featuring a USB-C port. Verify compatibility with your specific Lenovo system model before ordering, as connector availability and supported network speeds vary by host device and firmware. No additional driver installation may be required on supported Lenovo platforms, but confirm with your system's documentation.
