Why is my WiFi card not being detected by my operating system?
Your WiFi card may not be detected by your operating system due to a variety of reasons, including a faulty or loose connection, outdated or corrupted drivers, or a problem with the WiFi card itself. It’s also possible that the WiFi card is not properly seated in its slot or that there’s a conflict with another device. To troubleshoot the issue, start by checking the physical connection of the WiFi card and ensuring that it’s securely seated in its slot.
If the physical connection is secure, try restarting your computer and see if the WiFi card is detected. If not, try updating your WiFi card drivers to the latest version or uninstalling and reinstalling them. You can also try disabling and re-enabling the WiFi card in your device manager to see if that resolves the issue. If none of these steps work, it may be worth trying a different WiFi card or seeking further assistance from a technical support specialist.
How do I troubleshoot a WiFi card that’s not being detected in Windows?

Right-click on the WiFi card and select “Update driver” to search for and install the latest version. You can also visit the manufacturer’s website and download the latest drivers for your specific WiFi card model.
Once you’ve downloaded the latest drivers, follow the installation instructions to install them. Be sure to restart your computer after installing the new drivers to ensure that they take effect. It’s also a good idea to create a system restore point before updating your drivers in case something goes wrong during the installation process.
Can a faulty WiFi card be repaired or should it be replaced?
A faulty WiFi card may be able to be repaired, but it’s often more cost-effective and efficient to replace it. If the WiFi card is no longer under warranty, it may be worth trying to repair it yourself or taking it to a professional repair service. However, if the WiFi card is still under warranty, it’s best to contact the manufacturer for assistance.
In many cases, a faulty WiFi card is a sign of a larger issue with the computer or laptop itself. In this case, it may be worth considering replacing the entire device rather than just the WiFi card. Additionally, if the WiFi card is an older model, it may be worth upgrading to a newer model with better performance and features.
