Product details
The GL-2.5G (USB version) is a USB 3.0 to 2.5G RJ45 LAN adapter that delivers 2.5Gbps wired Ethernet speeds to any device with a USB 3.0 Type-A port. As 2.5G networking infrastructure becomes increasingly mainstream ? with 2.5G routers and switches now widely available ? the GL-2.5G provides a simple, cost-effective way to take full advantage of this faster network tier without requiring an internal NIC upgrade.
At 2.5Gbps, the adapter provides 2.5 times the throughput of a standard Gigabit (1G) LAN adapter. For users who transfer large files to NAS devices, back up significant amounts of data regularly, or work with high-resolution video content over a local network, the speed difference is immediately noticeable and practically significant. A file that takes 80 seconds to transfer over 1G LAN completes in approximately 32 seconds over 2.5G.
The USB 3.0 host interface ensures the adapter can utilise the full 2.5Gbps bandwidth without being bottlenecked by the connection to the host computer. USB 3.0’s 5Gbps maximum throughput provides sufficient headroom for the adapter to operate at its rated speeds without saturation.
The GL-2.5G is designed for plug-and-play operation, with driver-free recognition on most modern versions of Windows, Mac OS, and Linux. The setup experience is as simple as connecting the adapter to a USB port and plugging in an RJ45 cable ? no software installation required in most cases.
The adapter’s compact form factor makes it easy to carry as a travel accessory and suitable for permanent desktop placement alike. It does not require external power, drawing all operating current from the USB host port.
The GL-2.5G USB version is the recommended choice for desktop PC users and laptop users with USB-A ports who want to upgrade their wired networking to 2.5G speeds quickly and affordably.
