Attention: A single ethernet splitter does not support two devices to access the Internet at the same time. Only one device can be connected to the Internet at a time. Features: The splitter ethernet network adapter divides the original embedded Ethernet cable (8pins) into two (1236/4578) to transmit data through pure physical connection, without the function of assigning IP addresses. The speed of each cable set can only reach 100 megabytes, and the signal transmission does not interfere with each other. More Stable: Ethernet cable splitter adopts gold-plated needle core to shield external electromagnetic interference.  Fixed RJ45 interface, transmission signal more stable. Compatibility: This RJ45 1 male to 2 female ethernet splitter compatible with router, computer, switch, TV, set-top box, monitoring equipment. Suitable for Cat5, Cat5e, Cat6. RJ45 Ethernet Splitter: It converts the single RJ45 socket into two. Use it when you often use your laptop in two different rooms without having to pull the network cable back and forth.
