StarTech US2GA30 USB A to Ethernet Adapter
Overview
The StarTech US2GAB30 provides a reliable method to add a 2.5 Gigabit Ethernet port to a computer lacking one, or to upgrade an existing Gigabit port. This adapter connects via USB 3.2 Gen 1 (5 Gbps) and supports network speeds up to 2.5 Gbps, making it ideal for high-speed network environments, large file transfers, and demanding surveillance streams where Gigabit Ethernet is a bottleneck. Its compact, USB-powered design with an attached cable simplifies deployment in desktop or mobile workstation setups.
Compatibility
This adapter is compatible with any computer featuring a USB Type-A port supporting USB 3.2 Gen 1 or higher. It functions across Windows, macOS, and Linux operating systems. For network infrastructure, it supports 2.5GBASE-T, 1GBASE-T, and 100BASE-TX speeds, ensuring compatibility with existing network switches and routers, while enabling higher throughput with 2.5 GbE capable infrastructure. It is suitable for use with network video recorders (NVRs) or workstations requiring faster network access for surveillance footage.
Installation Notes
The adapter is powered directly from the USB host port, requiring no external power supply. It supports Jumbo Frames up to 9K, which can improve network efficiency for large data transfers by reducing the number of packets processed. VLAN tagging support (IEEE 802.1q) allows for network segmentation and traffic prioritization in managed network environments.
