About this project Solves the problem of insufficient router ports: The advantage of this adapter is that a laptop is frequently used in three different fixed positions, which is very inconvenient, and the network cable will cause disconnection. This rj45 1 to 3-way RJ45 Ethernet splitter helps you avoid the hassle of plugging and unplugging the cable back and forth. Solves the problem of insufficient network cables installed in the room: If one network cable is installed in your room, and you have three computers (or other devices like TVs), you can use this rj45 1 to 3-way RJ45 Ethernet splitter to help you achieve this. Avoids the hassle of plugging and unplugging the cable back and forth. Note: This is not a switch; it only allows three devices to use the network alternately and does not support three devices using the network simultaneously. Easily convert one RJ45 connection into three RJ45 outlets with this network splitter.
