If your network card is not detected then there are a few steps that you can try in order to get it working again. Below is an outline of the most common solutions:
1. Check the Network Card: The first step that you should take if your network card is not being detected is to ensure that it is securely and properly installed in your computer. Depending on the type of network card, you may need to open your computer’s case in order to inspect the card for any loose connections or other hardware issues. If the card appears to be seated correctly and all connections are secure, then there is no need to further investigate this issue.
2. Update Device Drivers: If your network card is still not being detected after ensuring that the physical connections are secure, then you may need to update your device drivers. If you are using an older network card, it may benefit from a driver update. To check for driver updates, visit the manufacturer’s website for your network card and follow their instructions.
3. Check Network Settings: It may be the case that your network card is being detected but it is misconfigured. Check the Windows Networking settings to make sure that the IP address and subnet mask are set correctly. Also, try enabling any wireless features to see if that fixes the problem.
4. Disable/Enable Network Card: A common fix for network cards that are not being detected is to disable and then enable them. To disable the network card, open the Device Manager, click on the network card, click on “Disable” and then restart your computer. Once the computer has restarted, re-enable the network card via the same method. The network card will now be detected by your computer.
5. Reset Your Network Settings: Sometimes, a corrupted file or setting can prevent your network card from being detected. You can reset all of your network settings by going to the Control Panel, selecting Network and Internet, clicking on Network and Sharing Center, and then clicking on “Reset Network Settings.” This will reset all of your network settings, including your IP address, back to their defaults.
6. Replace the Network Card: If none of the above solutions work then it may be necessary to replace the network card. Make sure to purchase the correct replacement card and contact the manufacturer for installation instructions.
It is important to note that these solutions should only be attempted after thoroughly troubleshooting the issue. Additionally, do not attempt any solutions that you are uncertain about as they could potentially damage your computer or create additional problems. If the issue persists after attempting all of the above solutions, then it may be best to contact a professional for assistance.
