TP-LINK UE330 is a compact, portable Ethernet adapter that allows you to connect your computer or laptop to a wired network. It supports Plug and Play feature, which means that it is ready to use as soon as you plug it in. The adapter is compatible with Windows 7, 8, and 10, as well as Mac OS X 10.8 and older versions.

The UE330 has two LED indicators: one for power and one for Ethernet activity. The power LED lights up white when the adapter is properly connected, and the Ethernet LED lights up yellow when the Ethernet cable is properly connected. The Ethernet LED also flashes green when network data is being transferred.
