3. 无法连接到互联网 如果无法连接到互联网，首先检查路由器和网络连接是否正常。尝试重启路由器和设备，并检查是否有其他用户报告相同的问题。如果问题仍然存在，请联系互联网服务提供商进行进一步排查。 三、文章翻译（英文版） Network Cable Connection Skills and Troubleshooting: Keep Your Network Smooth and Unblocked I. Network Cable Connection Skills 1. Selection and Check of Network Cable Choosing a high-quality network cable is the first step to ensure stable network connectivity. Check that the outer covering of the cable is intact and there are no breaks or damages. Also, ensure that the cable is not excessively bent or twisted, which may affect signal transmission. 2. Proper Use of RJ45 Connector When connecting network cables, RJ45 connectors are required. Proper installation of the connector ensures stable connectivity. When inserting the cable, make sure that the cable is arranged in the correct order (usually orange-white, orange, green-white, blue-white, blue, green, brown-white, brown). Use a professional cable crimper for cutting and crimping. 3. Proper Knotting of Twisted Pairs During cabling, the knotting method of twisted pairs is also crucial. The correct knotting method can reduce signal interference and attenuation. Common methods include twisting and up-down flipping. 4. Using High-Quality Network Interfaces and Devices At each node of the network connection, high-quality network interfaces and devices should be used. The quality of these devices will directly affect the stability and speed of the network.

1. Network not working First, check if the network cable connection is loose or disconnected. If the connection is normal, try replacing the cable or connector. If the problem persists, check if the network interface and device are working properly. 2. Slow network speed Slow network speed may be caused by various factors such as signal interference or device aging. First, check the network environment to ensure that there are no other devices or appliances causing interference. If the environment is normal, consider replacing or upgrading network equipment. 3. Unable to connect to the internet If you are unable to connect to the internet, first check if your router and network connection are normal. Try restarting your router and devices, and check if other users are reporting the same issue. If the problem persists, contact your internet service provider for further investigation and resolution.
