USB-C Gigabit Ethernet Adapter

This USB 3.1 Type-C to RJ45 adapter adds a wired 10/100/1000 Mbps network port to laptops, tablets or a Nintendo Switch that lack built-in Ethernet. It targets users who need a stable connection in Wi-Fi dead zones or prefer wired reliability for large downloads and streaming. The AX88179A chipset handles the conversion without requiring extra drivers on Windows 10, 8.1, 8 or macOS 10.9 and newer.

Sustained throughput on a 5 Gbps bus

The adapter runs on a USB 3.1 Gen 1 (5 Gbps) link, so the 1 Gbps Ethernet line rate is well within the bus capacity and does not saturate the host controller during long transfers. Auto-negotiation selects 10, 100 or 1000 Mbps automatically, while IEEE 802.3az Energy Efficient Ethernet reduces power draw during idle periods. Wake-on-LAN support lets the attached system wake from sleep for remote access without keeping the link at full speed continuously.

Driver-free on Windows 10/8.1/8 and macOS 10.9+

Plug-and-play operation on these operating systems means no manual driver installation is needed for the AX88179A chipset, making it immediately usable for travelers, remote workers or Switch gamers. Buyers whose primary device runs an older Windows version or a Linux distribution without the AX88179 driver in-kernel will need to obtain software separately before the adapter functions.

Questions about this item

Does the AX88179A chipset run hot or draw much power during all-day use?

The adapter uses an aluminium case that acts as a passive heatsink and supports IEEE 802.3az Energy Efficient Ethernet to keep power draw low during continuous operation.

What must my laptop already have to use this USB 3.1 Type-C to RJ45 adapter?

A free USB-C port that carries USB 3.1 or USB 3.0 signals; no driver installation is required on Windows 10, Windows 8.1 or macOS 10.9 and newer.

Will the gigabit link negotiate down to 10 or 100 Mbps on my older router or switch?

Yes, the AX88179A transceiver auto-senses and automatically switches between 10, 100 and 1000 Mbps, with crossover detection and auto-correction included.
