When a network card malfunctions, how to quickly and effectively troubleshoot and repair it becomes a topic worth exploring. This article will detail the troubleshooting steps and maintenance skills for network card failures. Troubleshooting: 1. Confirm the failure phenomenon: First, determine the symptoms of the network card failure, such as inability to connect to the network, slow network speed, intermittent network connection, etc. 2. Check hardware connections: Confirm that the network equipment such as cables, routers, switches, etc., are connected properly and that the network card is firmly inserted into the computer slot. 3. Check drivers: Check if the network card driver is installed correctly and if it is the latest version. If necessary, try reinstalling or updating the driver. 4. Check system settings: Verify that the computer's network settings are correct, such as IP address, subnet mask, gateway, etc. 5. Use diagnostic tools: Use Windows' built-in diagnostic tools or third-party software to diagnose and check for hardware issues.

Maintenance Skills:

1. Restart the network card: When a failure occurs, try restarting the network card first to resolve temporary issues. 2. Clean slots and network card: Clean dust from the computer slots and network card, reinsert the network card and secure it. 3. Replace cables or ports: Try replacing another cable or switching to a different port on the computer for connection. 4. Update drivers: If the driver is not the latest version, try updating it to the latest version. 5. Replace network card: If none of the above methods resolve the issue, it may be a hardware failure with the network card, and you may need to consider replacing it with a new one.
