Ugreen USB-C to RJ45 2.5G Ethernet Adapter interface cards/adapter RJ-45

The Ugreen USB-C to RJ45 2.5G Ethernet Adapter Grey provides a wired network connection for laptops, tablets and other devices with a USB Type-C port. With support for up to 2.5 Gbps throughput, this compact adapter converts a USB-C host interface to an RJ-45 Ethernet port, enabling reliable, low-latency connections where Wi‑Fi is limited or unstable. The grey housing offers a neutral look that integrates with most workstations and home setups.

Advantages

The adapter delivers faster-than-gigabit Ethernet speeds up to 2.5 Gbps for improved file transfers and smoother networked applications. Its USB Type-C host interface provides plug-and-play compatibility with many modern devices and requires minimal setup. The compact, lightweight design makes it easy to carry and use on the go, while the wired RJ-45 connection ensures stable bandwidth and reduced packet loss compared with wireless connections.

Suitable for

• Connecting laptops and tablets to wired networks for video conferencing and streaming
• Online gaming that benefits from lower latency and stable throughput
• Large file transfers and backups over a local network
• Workstations in offices or home setups without built-in Ethernet ports

Key specifications

• Host interface: USB Type-C
• Network interface: RJ-45 Ethernet
• Maximum supported data rate: 2.5 Gbps
• Product colour: Grey
• Form factor: Compact, external dongle

How to use

Insert the USB-C connector into an available USB Type-C port on the host device and connect a standard Ethernet cable to the RJ-45 port. Most operating systems will detect the adapter automatically and install required drivers; if prompted, follow on-screen instructions to complete driver installation. After connection, verify network settings in the host device to ensure the adapter is selected as the active network interface.

Recommendations

For optimal performance, use Cat5e or higher-rated Ethernet cables and connect to a 2.5G-capable switch or router when available. Avoid bending the adapter or cable sharply near the connector to reduce mechanical stress. If you experience connection issues, try a different USB-C port or update the host device’s network drivers.
