FORIDA 5Gb USB-C Ethernet Adapter

The FORIDA adapter adds a 5Gb RJ45 port to laptops that only have USB-C or Thunderbolt. It targets creators and IT professionals who need faster wired links for NAS transfers or stable streaming. The aluminium casing doubles as a heatsink for sustained throughput.

Driver installation on Windows 11

macOS 15 and above works plug and play, while Windows 11 and Linux Kernel 5.17 require a driver download before first use. The RTL8157 chip keeps power draw and heat low, and the hidden ventilation holes prevent throttling during long sessions at 5Gb or 2.5Gb speeds.

Requires USB 3.2 Gen2 10Gbps port and CAT6 cable

To reach the advertised 5Gb rate the host port must support USB 3.2 Gen2 10Gbps or higher, the router or switch must offer 5Gb Ethernet, and a CAT6 or better cable is mandatory. Without those three elements the adapter will fall back to lower speeds.

Questions about this item

How can I verify the 5Gb link is active after connecting the adapter?

Check the OS network status to confirm a 5Gbps link rate and run a transfer with a CAT6 or higher cable to a 5Gb-capable router or NAS; the Realtek RTL8157 chip will maintain that speed if the host port is USB 3.2 Gen2 or faster.

What comes in the box and what must I supply myself?

The adapter itself is included; you must provide a CAT6 or higher Ethernet cable and ensure your router, switch or server supports 5Gb Ethernet. Windows 11 and Linux Kernel 5.17 require driver installation, while macOS 15 and above is plug-and-play.

Which Thunderbolt version should I use for the 5Gb adapter?

The adapter is compatible with Thunderbolt 5, 4 and 3; any of those ports will work provided the host also meets the USB 3.2 Gen2 (10Gbps) minimum for full 5Gb throughput.
