(Note: This product is not a switch, so it can't connect two computers to the Internet at the same me) For example,

if you want to take a laptop and move it in two fixed rooms, use this tee head. One end is connected to the network

cable source, and the other end is connected to two network cables, which are wired to two rooms respecvely,

so you don't have to worry about being unable to surf the Internet without a crystal head aer changing rooms.

It's cheap and praccal!
