2. 网络信号不稳定：检查周围环境是否存在电磁干扰源，如电磁炉等设备。同时检查网线接头是否松动或脏污，以及是否存在物理损伤等问题。 3. 无法识别网络设备：检查设备连接是否正常，确认设备是否已正确连接到网络中。同时检查网线的长度是否超过了设备的支持范围。 五、英文翻译（译文） Network Cable Troubleshooting and Maintenance Skills In the modern information age, network cables are important connections, but due to their physical characteristics and usage environment, they may encounter faults, causing inconvenience in daily life and work when using the network. To ensure the stability and reliability of network connections, this article will introduce some skills for troubleshooting and maintenance of network cables. I. Common Causes of Network Cable Faults 1. Physical damage: The network cable may be broken or damaged due to external forces during installation or use. 2. Poor contact: Oxidation or looseness of the network cable connector may lead to poor network signal transmission. 3. Signal interference: The electromagnetic field in the surrounding environment may interfere with the signal transmitted by the network cable. II. Network Cable Troubleshooting Skills 1. Visual inspection: Check if the network cable has any breaks, twists, or obvious damage, and if the connectors are loose or dirty. 2. Substitution method: Use a normal network cable to replace the suspected one, and observe if the fault transfers to locate the problem. 3. Equipment connection method: Use computers, switches, and other equipment to gradually check the connection status of each segment of the network cable to determine the location of the fault. III. Network Cable Maintenance Skills 1. Regular inspection: Regularly inspect the network cable to identify and address problems in a timely manner. 2. Avoid physical damage: Avoid physical damage to the network cable during installation and use. 3. Keep it clean: Regularly clean dust and dirt from the network cable connectors to maintain their good electrical conductivity. 4. Correct wiring: Follow the correct wiring order and standards when connecting the network cable to ensure stable transmission of the network signal.

5. Storage protection: Store the network cable in a dry and dust-free place when not in use to avoid damage caused by environmental factors.

IV. Solutions to Common Problems 1. Network cable not working: First, check the physical condition of the network cable for any breaks or damage. Then use the substitution method to check if it is a device problem. Finally, check if the connectors are loose or dirty and perform corresponding processing accordingly. 2. Network signal instability: Check if there are electromagnetic interference sources in the surrounding environment, such as electromagnetic stoves. At the same time, check if there are issues with the physical condition of the network cable or if the connectors are loose or dirty. If you have more complex issues with your cable or if you are unable to fix a particular problem on your own, we
