USB Network Adapter LEVELONE USB-0402 V3 Gigabit USB-C adapter, gigabit Ethernet over USB-C

LEVELONE USB-0402 V3 Gigabit USB-C adapter provides wired Gigabit Ethernet connectivity through a USB-C port. It is designed to add or replace a wired LAN interface on laptops, ultrabooks and desktops that lack a built-in RJ45 jack. The adapter enables a stable, low-latency connection for file transfers, video conferencing and other network tasks where wireless links are insufficient.

Advantages

The adapter delivers up to 1 Gbps Ethernet performance over a single USB-C connection and supports automatic link negotiation for common network speeds. Its compact, plug-and-play form factor requires minimal setup and is suitable for mobile use. The metal-housed connector and integrated cable provide reliable physical connection and basic durability for frequent handling. Compatibility with standard network protocols ensures interoperability with switches, routers and networked devices.

Suitable for

• Connecting laptops or ultrabooks without Ethernet ports to wired networks
• Providing a stable connection for video calls, streaming and large file transfers
• Network troubleshooting and configuration tasks requiring wired access
• Desktop systems needing an additional or replacement Ethernet interface

Key specifications

• Interface: USB-C host connection
• Network standard: Gigabit Ethernet (10/100/1000 Mbps)
• Connector: RJ45 for wired LAN
• Data transfer rate: up to 1 Gbps (full duplex dependent on network)
• Power: bus-powered from host USB-C port
• Form factor: compact inline adapter with attached cable
• Compatibility: works with devices supporting USB-C with appropriate driver support

How to use

Plug the adapter's USB-C connector into a compatible USB-C port on your laptop, ultrabook or desktop. Connect a standard Ethernet cable to the adapter's RJ45 port and to your network switch, router or wall outlet. The adapter typically installs automatically on modern operating systems with built-in driver support; if required, install the manufacturer-provided driver following the system prompts. After the link lights indicate a connection, configure network settings on the host device as needed (DHCP or static IP).

Usage recommendations

For the best network performance, use quality shielded Ethernet cables and connect to Gigabit-capable switches or routers. Ensure the host device provides sufficient USB-C power and that any power-saving settings do not disable USB ports during use. When using in corporate or secured networks, confirm network authentication and VLAN settings with your IT administrator.
