Network cards can stop working for a variety of reasons, ranging from simple issues such as device driver installation to more complex cases involving hardware or software failure. Below are some of the most common causes for a network card to stop working:
1. Hardware Issues: The most likely cause of a network card not working is a physical issue such as a damaged or faulty card. In this case, the card needs to be replaced with a new one. Some signs of a damaged network card include an inability to detect network connections, no activity lights on the card, or limited speeds available when connected.
2. Device Driver Installation: A device driver is a small piece of software that allows a computer to communicate with its hardware components. If this driver is not installed correctly or updated, then the network card may not work. This can easily be fixed by downloading and installing the latest available driver from the manufacturer’s website.
3. Poor Network Connectivity: If the connection between the computer and the router is weak or spotty, then the network card will not be able to communicate correctly and stop working. This can be caused by a number of factors including; Distance between the two, physical obstructions such as walls, or even outdated technology.
4. Outdated Firmware: Firmware is the code that controls the functionality of the hardware. It is important to keep this up-to-date in order to ensure the best performance. If the firmware is out of date, then the network card may be unable to perform as expected.
5. Computer Compatibility Issues: If the computer is not compatible with the network card, then it may not be able to recognize and utilize it properly. This can be identified by looking at the list of compatible devices and making sure the computer’s operating system and other specifications meet the requirements.
6. Poor Configuration: If the settings for the network card are incorrect, then it may not be able to connect or function properly. This can be fixed by accessing the networking settings and configuring it according to the user manual.
7. Malware Infection: If a computer is infected with malware or viruses, then this can interfere with the network card’s performance. To fix this, it is important to run a scan and remove any malicious files or programs.
8. Bad Cables: If the cables connecting the computer and router are damaged, then they may not be able to provide a stable connection to the network card. This can be resolved by replacing the cables with newer ones.
9. Network Card Overheating: Network cards can overheat due to prolonged usage or dusty ventilation. This can be solved by cleaning any dust buildup, or turning off the computer and letting it cool down.
10. Interference: Network cards can sometimes experience interference from other devices in the area, such as cordless phones or microwaves. This can be fixed by moving the device away from the router or installing a signal booster.
