2.5 Gbps Ethernet Adapter

The KINGARD USB-C to Ethernet Adapter provides a wired 2.5 Gbps network connection for laptops, tablets and phones that lack a built-in RJ45 port. It uses a Realtek RTL8156BG controller and is backwards compatible with 1 Gbps, 100 Mbps and 10 Mbps networks. An aluminium housing aids heat dissipation and durability.

Check USB-C Port and Cable

Verify that your device’s USB-C port supports data transfer and is not power-only. The adapter works with Thunderbolt 3 and Thunderbolt 4 ports, but a charge-only port will not pass Ethernet traffic. Use a cable rated for at least USB 3.1 Gen 1 to avoid bottlenecks.

Aluminium Housing and Reinforced Ports

The metal casing acts as a passive heatsink, keeping the RTL8156BG chip cooler during sustained 2.5 Gbps transfers. Reinforced USB-C and RJ45 connectors resist wear from frequent plugging and unplugging. No driver disc or configuration software is bundled; the adapter relies on in-box operating-system drivers.

Questions about this item

Does the KINGARD USB-C to Ethernet Adapter 2.5G include any cables or drivers in the box?

The adapter is a single aluminium unit with an integrated USB-C plug and an RJ45 port; no separate cables or driver discs are supplied.

Which speed rating should I choose if my router only supports 1 Gbps?

The adapter is backwards compatible with 1000, 100 and 10 Mbps, so it will negotiate the highest speed your router allows.

What does the 2.5 Gbps headline figure mean when I plug this into my laptop?

It means the Realtek RTL8156BG chip can sustain up to 2.5 Gbps throughput over the USB-C link, provided the host port and network infrastructure also support that rate.
