Wired Ethernet over USB 2.0

The JacobsParts USB-LAN-02 adds a 10/100 Mbps RJ45 port to any computer with a USB 2.0 socket. It draws power directly from the bus so no external supply is needed. The Realtek RTL8152b chipset provides native support for Windows 11 down to XP, Linux and Mac OS X without manual driver installation.

Fits a spare USB-A port and a standard patch cable

The adapter occupies a single USB 2.0 Type-A connection and presents a regular RJ45 jack for Cat5 or Cat5e cabling. Because it is bus-powered, it adds no cable clutter or mains dependency. The 480 Mbps USB 2.0 bandwidth leaves headroom for the 100 Mbps Ethernet link without saturating the host controller.

Handles 10/100 Mbps LAN traffic.

The link negotiates at 10 or 100 Mbps full-duplex, which is adequate for typical internet access, office file shares and streaming. It cannot reach 1000 Mbps speeds, so users with gigabit infrastructure will see a bottleneck. The USB 2.0 interface also limits throughput to well below the 480 Mbps theoretical maximum.

Questions about this item

Will the USB 2.0 bus limit my 100 Mbps wired speed during long transfers?

The adapter runs at 10/100 Mbps over a USB 2.0 bus rated at 480 Mbps, so the wired link stays the bottleneck.

Does the Realtek RTL8152b chipset run hot or draw much power when the link is active all day?

It is USB bus-powered with no external supply, so heat and draw stay low enough for continuous use.

Do I need a separate RJ-45 cable and a free USB-A port to use this adapter?

Yes, you supply the Ethernet patch cable and plug the adapter into an available USB 2.0 Type-A socket.
