Seten: Network Card Hardware Faults and Solutions

Date:December 12th,2023 View:54
Network card failure is one of the most common causes of wired network failures. Once the network card malfunctions, it will lead to slow connection speed, intermittent or even lost connections, or inability to connect to the network. Therefore, if you want to maintain stable network connections, you must learn to solve network card failures< Br/>


Network card hardware faults and solutions



When the network card malfunctions and cannot function, the first step is to troubleshoot and resolve the hardware issue. As follows:



Firstly, check all physical connections to ensure that all network cables, fibers, and network cards are securely and correctly inserted into ports or slots. If there is no looseness and all connections are correct, you can try unplugging and reinserting the network card. If you cannot connect to the network even after reinserting, you can jump to the next step< Br/>


Secondly, check the LED indicator light of the network card. If the link indicator light is not on, it indicates that the physical connection cannot access the network, which may be a problem with network devices (such as computers or servers) or the network itself. Firstly, you can try inserting cables or network cards into different ports or slots to check if the ports or slots are damaged. If the problem is still unresolved, you can use a new cable or network card for replacement inspection to see if the cable and network card are damaged. If you do not have a new cable or network card, you can install the network card on another computer or server for testing. If the problem remains unresolved after the above operation, it is necessary to confirm whether the network card is compatible with network devices (such as computers or servers). You can check whether it is compatible from three aspects: brand, transmission rate, and port type< Br/>


Thirdly, check the status of the network card. After the above two steps, the problem has not been resolved. You can use&quo; Device Manager; To verify if the computer or server recognizes the network card. If it is not recognized, go directly to the troubleshooting section of the network card software< Br/>


a. Use the Win+R shortcut key on the computer to open the runtime window< Br/>


B. b Enter&quo; in the input box; Devmgmt. msc”, Then click on&quo; Confirm; Button, open&quo; Device Manager; Interface< Br/>


C. c Click on the Network Adapters in the Device Manager interface, expand All, find your network adapter (which is actually a network card), and double-click. At this point, you can go to" Regular; I saw the status of the network card in the middle. If&quo; is displayed on this page; This device is running normally;, This indicates that the network card is working properly; If not, it indicates that there may be a problem with your network card< Br/>


Fourthly, check for resource conflicts in the operating system. Check for resource conflicts between the network card and other system components. Generally speaking, most servers can set the network card in their BIOS program not to share IRQ with the SCSI or RAID controller< Br/>


A. a Press F1 to enter the BIOS setup program during startup< Br/>


B. b Enter&quo; Advanced Settings/PCI Slot/Device Information (or PCI Bus Control); Interface, select the slot or device that needs to be higher< Br/>


C. c Disable all unused devices and free up resources (serial ports, parallel ports, etc.)< Br/>


Fifth, check the network settings in the operating system to ensure that all network protocols and hardware (cables, hubs, switches, etc.) are set up correctly. All IP addresses should be unique, and DHCP can automatically and correctly allocate TCP/IP protocol addresses< Br/>


Sixth, confirm whether the TCP/IP protocol (or other protocols) is installed correctly. You can perform the following operations on Microsoft Windows to check if it is installed correctly< Br/>


A. a Right click; Online Neighbors; Icon, select&quo; Properties;, Open&quo; Local Connection; Interface< Br/>


B. b Right click; Local Connection;, Select&quo; Properties;, If you see&quo; in the window; Internet Protocol (TCP/IP);, This indicates that the TCP/IP protocol has been installed. If no&quo; is found; Internet Protocol;, It indicates that it is not installed< Br/>


C. c If the TCP/IP protocol is not installed, click&quo; Installation;, Perform&quo; Protocol; Add, select&quo; TCP/IP;. Protocol and click&quo; OK; Add< Br/>


D After installation, if using DHCP, make sure to select&quo; Automatically obtain IP address; And&quo; Automatically obtain DNS server address;. If you want to verify whether it is selected, you can click on&quo; TCP/IP protocol;, Select&quo; Properties; Review. (Note: If your network or service provider requires a static IP address, please use only one static IP address.)



Seventh, verify the TCP/IP address. Perform the following operations in Microsoft Windows:



A. a Click on Start, select Program&flash& Flash; Attachment&flash& Flash; Enter the command prompt interface with the command prompt< Br/>


B. b Enter&quo; Ipconfig” Command enter to display the IP address of the computer< Br/>


C. c If returning 169. x.x.x or 0.0.0If the address is. 0, enter&quo; Ipconfig/release” And&quo; Ipconfig/renew” Command. At this point, you will receive the appropriate TCP/IP address and default gateway address for your network< Br/>


D Attempt to input&quo; Ping x.x.x.x” Command to communicate with it (where x.x.x.x is the default gateway IP address)< Br/>


E If you have not received a reply or a TCP/IP address, proceed to the next step< Br/>


Eighth, ping the return address. Perform the following operations in Microsoft Windows:



A. a Click on Start, select Program&flash& Flash; Attachment&flash& Flash; Enter the command prompt interface with the command prompt< Br/>


B. b Enter&quo; Ping 127.0.0.1” Command (used to test if the network card driver is installed properly) Enter. You will see the following response:



Ping 127.0.0.1 with 32 bytes of data:



Reply from 127.0.0.1: Byte=32 Time<1ms TTL=128



Reply from 127.0.0.1: Byte=32 Time<1ms TTL=128



Reply from 127.0.0.1: Byte=32 Time<1ms TTL=128



Reply from 127.0.0.1: Byte=32 Time<1ms TTL=128



Ping statistics for 127.0.0.1:



Packet: Sent=4, Received=4, Lost=0



Estimated time for round-trip travel (in milliseconds):



Min=0ms, Max=0ms, Avg=0ms



Ninth, ping the IP address of the system. To further solve the network card problem, you can connect the system directly to another system or client through twisted pair or hub. Set TCP/IP using two consecutive addresses (such as 10.1.1.1 and 10.1.1.2) and the default subnet mask (255.0.0.0). In the command prompt interface, try ping the client IP address. If the system receives a response, it indicates that the network card is functioning properly. If there is no response, you can go to the following software section< Br/>
