3>2mm thick PCB board embedded conductive circuit to avoid damage to the conductor leakage. Ensure a longer service life. Pure copper plated gold needle (eight core): more stable transmission, excellent connection, and transmission. The fixed RJ45 female interface shields external electromagnetic signal interference to prevent damage to the Internet signal. Transmission is more stable, it has a superior connection and transmission. The screw hole panel can be fixed to the wall panel. 4>Solve the router port number is not enough: This adapter Advantage Design: A notebook in three different fixed positions often back and forth use, this is very trouble, the network cable to lead to broken, this rj45 1 to 2 ways RJ45 ethernet splitter help you do not have to pull back and forth cable.
