As the cornerstone of network connection, network cards, once experiencing faults, will directly affect the entire network's operation. Therefore, it is crucial to correctly troubleshoot and optimize network card issues. Common Causes of Network Card Faults: 1. Hardware issues: such as physical damage, poor contact, or aging. 2. Driver problems: Incompatible or outdated drivers can cause the network card to malfunction. 3. Network settings issues: IP address conflicts, incorrect network configurations, etc. 4. Virus or malware infection: which can cause abnormal network card communication. Steps for Troubleshooting Network Card Faults: 1. Hardware inspection: Observe for any physical damage to the network card and check the connection with the motherboard for firmness. 2. View system logs: Check the system logs for any error messages related to the network card. 3. Update drivers: Check if the drivers are up to date; if not, update to the latest version. 4. Check network settings: Verify IP address, gateway, DNS, and other settings for correctness. 5. Virus scan: Run a full system virus scan to ensure no malicious software is interfering. Measures for Optimizing Network Card Performance: 1. Clear cache: Regularly clear system cache to improve network transmission efficiency. 2. Change channel: If using a wireless network card, try changing the channel to avoid signal interference. 3. Adjust network protocols: Adjust network protocol parameters based on actual needs to improve network performance. 4. Increase bandwidth: Consider upgrading bandwidth if frequent network congestion is experienced.

5. Upgrade hardware: If the network card is outdated or severely aged, consider upgrading to a newer model.
