The Lenovo 4X90L66917 is a wired Ethernet network card that connects to devices via USB Type-C. Designed in black with a compact form factor and a listed weight of 0.044 kg, this adapter provides a physical RJ45 network interface for systems that lack a built-in Ethernet port. The product targets users who need stable wired connectivity for desktop PCs, laptops and compatible tablets through a USB-C connection.

Advantages

The adapter delivers a direct wired Ethernet connection over a USB Type-C interface, offering consistent network performance and reduced latency compared with wireless connections. Its compact black housing and lightweight design make it easy to carry and install without adding noticeable bulk. The simple plug-and-play approach allows quick connection to networks where a reliable wired link is preferred.

Suitable for

• Connecting laptops or tablets with USB Type-C ports to wired Ethernet networks
• Office workstations requiring stable and low-latency network access

How to use

Connect the Lenovo 4X90L66917 to an available USB Type-C port on the host device. Plug a standard Ethernet cable into the adapter's RJ45 port and connect the other end to a router, switch or wall jack. The device is intended for straightforward setup; many operating systems will detect the adapter automatically and configure network settings via DHCP. If required, install any vendor or operating-system drivers following the system prompts or the device documentation.

Recommendations

For best results, use a high-quality Cat5e or higher Ethernet cable and connect to a known good network port. Avoid placing heavy strain on the USB-C connector or bending the cable sharply. Verify driver availability on older operating systems before deployment to ensure compatibility.
