Welcome to the store! [Three Connection Methods] Two computers share one Ethernet cable simultaneously. The router and set can be connected to the Internet at the same time, or the router can be used to loop back the signal to other devices. [Connection Method]: If two computers need to access the Internet at the same time, when the router is far away from the computer, only one network cable with 8 cores is needed between the two rj45 splitters, but two computers are required at the same time. [Physical Data Transfer] The RJ45 Ethernet distributor splits the original built-in Ethernet cable (8 pins) into two groups (1234/5678) and transmits data with a pure physical connection. [Function] Specifically designed to solve weak WiFi signals in the network and connection problems caused by insufficient wiring, such as basements, attics, remote houses, 2 or more devices online. [Note] A pair of RJ45 splitters must be used together; just one cannot complete the network connection of two devices simultaneously. Simple operation, cost savings, configuration, and use.
