What this adapter does

The No Sew WL-NWU341G adds a 5Gbps RJ45 port to any USB-C device that runs USB 3.2 Gen 2 or higher. It targets users who need wired multi-gig throughput for large file moves, server access or low-latency streaming.

Check your port and cabling first

The host must expose a USB-C port rated for USB 3.2 Gen 2 (10Gbps) to reach 5Gbps; slower ports will fall back to 2.5G or 1G. You also need CAT6 or better cable plus a router, switch or NAS that supports 5GbE.

Aluminium shell with short tether

The grey aluminium-alloy body measures 3.1 x 1.2 x .7 in and weighs 65 grams, using its case as a heatsink during sustained transfers. A 5.91 in captive cable keeps the dongle close to the laptop, while LEDs show green for 5Gbps and amber for 10/100/1000/2.5G links.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The box contains the adapter with an integrated 5.91 in USB-C cable and one RJ45 port; you must supply your own CAT6 or better Ethernet cable to reach 5Gbps speeds.

Which version should I choose if my laptop only has a USB 3.2 Gen 1 port?

This single model requires a USB-C port with USB 3.2 Gen 2 (10Gbps) or higher to unlock 5Gbps; on a Gen 1 port it will fall back to 1Gbps or 2.5Gbps negotiation.

What does the 5Gbps headline figure mean once the adapter is plugged into my MacBook?

You will see up to 5Gbps only if the MacBook has an M3 or newer chip, the USB-C port supports 10Gbps, and your router or switch also supports 5Gb Ethernet; otherwise the green LED stays amber at 2.5Gbps or 1Gbps.
