It helps you expand network ports and solve connection problems caused by insufficient cabling. Note: It must be powered on during use. 【Gigabit High-speed Transmission】: This Ethernet splitter has a transmission speed of up to 1000Mbps, ensuring stable and fast data transmission. Whether you are transferring files, watching movies, or playing online games, you will enjoy an efficient online experience. Note: 4 computers can only share 1000M network bandwidth. When connected to one computer, it can support up to 1000M. This speed data is the maximum value of the chip, and the actual speed is subject to the connected device.
