  • Adds a Gigabit RJ45 port via USB 3.0 for 1000 Mbps wired speed
  • Works with Windows XP through Windows 10 and Mac OSX 10.6 or 10.7
  • Falls back to USB 2.0 or 1.x hosts without losing basic connectivity

  • Detects straight or crossover cables automatically and supports Jumbo frames up to 9 KB

USB 3.0 Gigabit Ethernet Adapter

The JacobsParts UB3-LAN-D adds a single RJ45 port to any USB-enabled computer, delivering gigabit network speeds at the full 1000 Mbps bandwidth. It suits laptops, desktops or tablets that lack a built-in Ethernet jack or need a replacement for a failed port.

Broad OS and legacy USB support

The adapter works with Windows XP through Windows 10 and Mac OS X 10.6 and 10.7, and remains backward compatible with USB 2.0 and 1.x hosts. Auto-MDIX detects straight or crossover cables automatically, while jumbo-frame support up to 9 KB and remote wake-up via magic packet reduce configuration effort.

Gigabit throughput on USB 3.0.

On a USB 3.0 connection the link runs at 10, 100 or 1000 Mbps with auto-sensing, giving full gigabit headroom for wired LAN traffic, large file transfers and low-latency gaming. When plugged into USB 2.0 the bandwidth ceiling drops to the host controller’s maximum, so sustained gigabit rates cannot be reached.

Questions about this item

Will the USB 3.0 connector on this UB3-LAN-D adapter wear out from repeated plugging?

The adapter uses a standard USB 3.0 plug rated for typical insertion cycles; no user-serviceable parts exist, so the whole unit is replaced if the connector fails.

What limits sustained throughput on this Gigabit Ethernet adapter during long transfers?

The USB 3.0 interface and 10/100/1000 Mbps auto-sensing set the ceiling; real-world speed also depends on the host controller and cabling quality.

Does the UB3-LAN-D run hot or draw noticeable power when left active all day?

It supports suspend mode and remote wake-up via magic packet, reducing heat and power draw during idle periods; no fan or heatsink is fitted.
