Portable Gigabit Ethernet adapter

This Jansicotek USB 3.0 to RJ45 adapter adds a wired Gigabit network port to laptops or desktops through a standard USB Type-A connection. It targets users who need a stable, low-latency link for file transfers or streaming, or who must replace a failed onboard network interface. The compact dongle is powered directly from the USB port and requires no external supply.

Check host port and OS compatibility

Verify that your computer has an available USB Type-A port and runs Windows 2000 through Windows 8.1 (32-bit or 64-bit) or macOS 10.6 or later. The adapter does not support Windows RT, Android, Wii, Wii U or Nintendo Switch. Driver-free installation relies on native OS support; ensure the operating system is up to date before connecting.

Build quality and daily connectivity

The small, hand-sized enclosure is designed for travel and desk use without blocking adjacent ports. A single RJ45 jack accepts Cat 6 or lower Ethernet cables for 10, 100 or 1000 Mbps links, with auto-negotiation and auto-MDIX handling cable polarity. LED indicators show link status and activity, while Wake-on-LAN and Energy Efficient Ethernet (IEEE 802.3az) reduce idle power draw.
