Introduction In modern computer and network technology, network cards, as critical devices for network connectivity, directly affect the stability and performance of the entire network system. Therefore, mastering the fault diagnosis and repair methods of network cards is crucial for network maintenance personnel. This article will provide a detailed introduction to the common faults of network cards and their diagnosis and repair methods. II. Common Faults of Network Cards 1. Physical faults: including damaged network card hardware, loose interfaces, damaged connection lines, etc. 2. Configuration faults: such as IP address conflicts, driver incompatibility, etc. 3. Network problems: such as unstable network connections, slow data transmission speeds, etc. III. Fault Diagnosis Methods 1. Observation method: judge whether there are physical faults by observing the indicator lights and connection lines of the network card. 2. Testing method: use network testing tools, such as Ping command, Traceroute, to detect whether the network connection is normal. 3. Checking method: check the configuration information of the network card, such as IP address, subnet mask, to ensure correct configuration. 4. Replacement method: replace the suspected faulty network card with a spare network card to see if the problem can be solved. IV. Fault Repair Methods 1. Physical fault repair: for physical faults, first check if the connection lines, interfaces, etc. are loose or damaged. If necessary, replace the hardware equipment with new ones. 2. Configuration fault repair: check the configuration information of the network card, such as IP address, subnet mask, to ensure correct configuration. If necessary, reinstall or update the driver. 3. Network problem solution: for issues such as unstable network connections and slow data transmission speeds, try optimizing network settings, upgrading network card firmware, or replacing network equipment methods.

4. Preventive measures: regularly inspect and maintain the network card to ensure it is in good condition. At the same time, pay attention to network security to avoid network card failures caused by viruses or malicious attacks.
