This adapter utilises the high bandwidth of the USB (Universal Serial Bus) 3.0 port to support true Gigabit Ethernet speeds. This flexible solution requires no external power supply, simply connect the adapter to an available USB (Universal Serial Bus) 3.0 port, install the included software driver & connect a Cat 5 cable from the adapter to an RJ45 Network port. With speeds up to 1000 Mbps, file transfer between computers is fast & easy, even with large amounts of multimedia data. The adapter works on new computers that do not provide a wired Ethernet port or legacy computers which have a damaged Ethernet port.
