StarTech.com USB 3.0 Gigabit Ethernet Adapter 1-Port

Brand:

The StarTech.com USB 3.0 Gigabit Ethernet Adapter adds a single RJ45 Gigabit Ethernet port to a laptop or desktop through USB 3.0. It supports 10/100/1000 Mbps Ethernet, USB 3.0 at up to 5 Gbps, VLAN tagging, Wake-on-LAN, Jumbo Frames, Auto-MDIX, and checksum offload. Its compact, USB-powered design provides a practical wired-network upgrade or replacement for systems without a working Ethernet port.

OVERVIEW

  • The StarTech USB31000NDS is a compact USB 3.0-to-Gigabit Ethernet adapter with one RJ45 port for adding or replacing wired LAN connectivity. Compatibility: computers with an available USB 3.0/2.0 port and 10/100/1000 Mbps Ethernet networks. Model comparison: USB31000NDS is the compact dongle version; USB31000S uses an attached cable design.

USE CASES

  • Laptop wired-network upgrade: Adds Gigabit Ethernet to systems without an integrated RJ45 port, providing reliable wired connectivity.
  • Desktop network expansion: Adds a network interface through USB without installing an internal PCIe network card.
  • Failed Ethernet-port replacement: Provides an external alternative when an integrated LAN interface has failed, avoiding chassis opening or hardware replacement. 
  • IT support and troubleshooting: Gives technicians a portable Ethernet interface for network testing, diagnostics and temporary connectivity.
  • Business workstation connectivity: Provides wired 10/100/1000 Mbps networking for office systems where stable Ethernet connectivity is preferred over Wi-Fi.
  • VLAN-enabled environments: IEEE 802.1Q VLAN tagging support makes the adapter suitable for compatible network segmentation requirements. 
  • Wake-on-LAN deployments: Supports WOL for compatible systems, useful for remote-management workflows
  • Legacy system connectivity: USB 2.0/1.x backward compatibility allows broader host compatibility, although network performance is limited by the USB bus.
