line refers to Signals, such as signals fed back by the Internet. And data refers to data, wifi, etc. When line connects to modern, data transfers information. The line is always on, which means the wireless signal is normal. It usually stays on when the wireless signal is turned on in the router. The flashing indicates that there is a device connected to the Internet through WiFi.

4. The optical modem is faulty, causing the fiber optic signal to be unable to be converted normally.

Network structure diagram of router operation

Router is a device that connects two or more networks A hardware device that acts as a gateway between networks is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. It can understand different protocols, such as the Ethernet protocol used by a local area network and the TCP/IP protocol used by the Internet. In this way, the router can analyze the destination addresses of data packets from various types of networks, convert the addresses of non-TCP/IP networks into TCP/IP addresses, or vice versa; and then route each data packet according to the selected routing algorithm. Deliver the best route to the specified location. So the router can connect non-TCP/IP networks to the Internet.
