The ThinkPad USB 3.0 Ethernet adapter enables the use of Ethernet on systems that do not have an Ethernet port (RJ-45) via the USB port on the system. The ThinkPad USB 3.0 Ethernet adapter not only offers a high-speed Gigabit Ethernet solution via the USB 3.0 port, but can also boot via LAN on selected ThinkPad systems. This allows you to connect your Ultrabook or tablet to your company VPN in the office or even in a hotel room. Due to its small form factor, the adapter fits in any computer case or carrying bag and can therefore be easily transported.
