For example, if you want to use a laptop in two fixed rooms, use this three-way connector, connect one end to the network cable source, and connect the other end to two network cables and connect them to two rooms respectively , so you don't have to change the room without crystals. I can't access the internet and I worry about that. Cheap and practical!
It can only be used with a single extension cord.
(Note: This product is not a switch, so two computers cannot be connected to the Internet at the same time)
