What this adapter adds

This TelDaykemei USB 3.0 to RJ45 adapter gives a laptop or desktop a 2.5Gbps wired Ethernet port through a single USB 3.0 connection. It is aimed at users who need faster and more stable network throughput than a standard gigabit port or wireless link can provide.

Who it suits and who should look elsewhere

It suits owners of Windows 8, 10 or 11 machines, recent MacBook Pro models from 2016 to 2019, and Linux systems that support the RTL8156B controller. Buyers who need a Type-C connector instead of USB-A, or who require driver-free operation on Windows 7 or older macOS releases, should look at a different adapter.

The spec that decides fit

The decisive specification is the 2500Mbps 2.5G Ethernet rating delivered over a USB 3.0 bus with the RTL8156B chip. If your workflow demands that exact throughput and chip-level compatibility, this adapter matches the requirement.

Questions about this item

Does my laptop need a USB 3.0 port to use this 2500Mbps adapter?

Yes, the adapter connects through a USB 3.0 interface to deliver the full 2.5G link rate.

Will the adapter work with my existing gigabit switch and Cat5e cables?

The RTL8156B chip negotiates down to gigabit speeds, so the link will come up at 1Gbps on your current hardware.

How can I verify the adapter is running at 2.5G after I plug it in?

Open the network adapter status on Windows or System Information on macOS and confirm the link speed shows 2.5Gbps or 2500Mbps.
