1. Check Physical Connection: First, check if the network cable is properly connected to the router, switch, computer, and other devices. If there is any loose or unconnected situation, re-plug and ensure a stable connection. 2. Test Network Line: Use a tool like a wire tester to test the connectivity of the network cable. If there is a disconnected line, it may be due to a broken or poor connection inside the cable. 3. Observe Device Status: Observe the status indicators of devices like routers and switches. If you notice abnormal flashing or no response, it may be a device fault or connection issue. II. Solutions: 1. Replace the Network Cable: If it is determined that the problem is caused by a broken or poor connection inside the network cable, try replacing it with a new one. Ensure that the new cable has the same specifications as the original to avoid compatibility issues. 2. Re-plug Device Connections: Sometimes, re-plugging the connections of devices like routers, switches, and computers can solve connection issues. Be careful not to use too much force during the process to avoid causing new damage. 3. Restart Devices: Sometimes, device faults can be caused by prolonged operation. Try restarting the router, switch, computer, and other devices to see if the problem can be resolved. III. Precautions: 1. Safe Operation: Ensure that the power is turned off during troubleshooting and repair to avoid electric shock hazards. 2. Careful Observation: Be careful to observe changes in device status and indicators during the troubleshooting process to accurately determine the problem. 3. Record Issues: Record the problems encountered and solutions during troubleshooting and repair for future maintenance and reference.
