Faster Than Gigabit—Double the performance of a traditional Gigabit Ethernet adapter when used with switches or routers capable of 2.5Gbps for faster file transfers, smoother video conferencing, and seamless streaming. Keep USB Universal—Hybrid 2-in-1 cable converts from USB-C to USB-A so you always have the right connection (USB 3.0 required for full performance). Use Existing Cabling—Upgrade your network without updating your cables. 2.5 Gigabit Ethernet signals are designed to work on Cat 5e cabling, just pair your USB Ethernet Adapter with 2.5Gbps-capable switches/routers. OS Compatibility—Works with Windows 11, 10, 8.x, and 7, macOS 10.7 and above, and Linux Kernel 3.2 and above. Driver download and install may be required on older OS and Kernel versions. Some core features require driver install on macOS. Get the Most out of Wired Connection Speeds. The Plugable 2.5Gbps USB to Ethernet Adapter (Usbc-E2500) is for users looking to move beyond Gigabit Ethernet speeds. With Usbc-E2500, you can leverage existing Cat 5e Ethernet cables and use less-costly switches to more than double the performance of your local network, compared to traditional Gigabit Ethernet.
