  • Supports Wake-on-LAN for remote power management

USB-C to 2.5G Ethernet Adapter

This adapter adds a 2.5 Gigabit RJ45 network port to any device with a USB Type C connector. It serves users who need a replacement for a failed internal NIC or an additional routable interface for peer-to-peer file transfers. The RTL8156B chipset provides driver-free operation on macOS, Windows 8, 10 and 11. Windows XP and 7 require a driver installation before use.

Sustained 2.5Gbps throughput via USB 3.0

The controller implements the IEEE 802.3 bz standard and negotiates 2500, 1000 or 100 Mbps links automatically. Real-world transfer rates for large video, audio and graphics files remain stable at the negotiated speed because the USB 3.0 bus supplies sufficient bandwidth for continuous 2.5G traffic. Backward compatibility ensures the adapter still functions on older 100 Mbps networks without configuration changes.

Low heat and silent operation

The compact RTL8156B chipset runs cool during extended data streams, so the aluminium housing stays near ambient temperature without active cooling. Power management features reduce draw when the link is idle, and Wake-on-LAN support allows the host to be woken from sleep over the network. No fan noise is produced because the design is completely passive.

Questions about this item

Does the RTL8156B chipset run hot or draw much power when transferring at 2.5 Gbps all day?

The adapter uses a USB 3.0 Type C bus-powered design with advanced power management features, so it draws only what the host port supplies and stays cool during sustained 2.5 Gbps transfers.

What port must my laptop already have for this adapter to work at its rated 2.5 Gbps speed?

A USB 3.0 Type C port is required; the note states that a USB Type C interface limited to USB 2.0 will only reach 10/100 Mbps.

Will this adapter work reliably alongside my older Cat 5e cabling and 1 Gbps switch?

Yes, it is backward compatible with 1000/100/10 Mbps networks and follows the IEEE 802.3 bz standard, so it negotiates down to 1 Gbps or 100 Mbps on legacy cables and switches.
