5G Ethernet Adapter for USB-C

The Ubiquiti Networks UniFi 5G Ethernet Adapter adds a high-speed wired network port to any device with a USB-C connection. It is designed for professionals who need reliable 5 Gigabit throughput without installing an internal card. The compact form factor suits both desk and mobile workflows.

Replaces slower USB Ethernet dongles

This adapter replaces older USB 3.0 or 2.0 Ethernet dongles that cap at 1 Gigabit or less. The jump is worth it when transferring large files, running virtual machines over the network or backing up to a NAS at multi-gigabit speeds. It removes the bottleneck imposed by single-gigabit USB adapters.

Check USB-C port capability and driver support

Verify that your USB-C port supports data transfer and not just charging. Confirm the host operating system includes or can load the required driver for 5G Ethernet operation. Ensure any docking station or hub between the adapter and the host passes through the necessary bandwidth.
