2.5G USB-A and USB-C Ethernet adapter

This adapter adds a 2.5Gbps wired network port to laptops, tablets or desktops that lack built-in Ethernet. It carries both USB-A and USB-C plugs on a single cable so you can connect to either port type without carrying a separate dongle. The device draws power from the USB bus and requires no external supply. It targets users who need faster-than-gigabit throughput for large file transfers, 4K streaming or low-latency gaming on the go.

Check your host port and cable before ordering

The adapter reaches 2500Mbps only when the host side is a USB 3.0 or USB 3.1 port; on USB 2.0 or 1.1 it falls back to lower speeds. Your router or switch must also support 2.5G, 1000, 100 or 10Mbps negotiation and you need a Cat 5e or better Ethernet cable to achieve the rated rates. Driver-free operation is listed for Windows 11, 10, 8.1, 8, MacOS, Chrome OS and Android, so verify your OS version is in that set.

Sustained throughput with aluminum heat dissipation

The aluminum shell acts as a passive heatsink, helping the controller maintain 2.5Gbps throughput during long transfers instead of throttling after a short burst. The PVC-jacketed cable is rated for over 10000 bend cycles, reducing the risk of intermittent disconnects when the adapter is moved repeatedly. A yellow-green LED shows link and activity status so you can confirm the connection remains stable under continuous load.

Questions about this item

What comes in the box with the Lamroyce USB A+C to RJ45 2.5G adapter?

The box contains the adapter unit with integrated USB-A and USB-C connectors and an RJ45 port. No separate cables or power supply are included because the adapter draws power from the host USB port.

Which version of the adapter should I choose for a laptop that only has USB-A ports?

The single model Lam-USB A+C-RJ45-2.5G includes both USB-A and USB-C plugs on one device, so it works with either port type without needing a different SKU.

What does the 2500 Mbps rating mean when the adapter is connected to a USB 3.0 port?

USB 3.0 provides enough bandwidth for the adapter to reach its full 2500 Mbps (2.5 Gbps) Ethernet speed, provided the network switch and cabling also support 2.5G operation.
