How to enable or disable Microsoft Windows Firewall.

Restore Windows to a Previous Copy

If you are using Microsoft Windows and Wi-Fi has worked in the past, try restoring Windows to an earlier copy. In some cases, the wrong settings or software may have caused problems with your Wi-Fi adapter or problems with Windows accessing the Internet connection.

How to restore Windows to a previous copy.

Reinstall the drivers and wireless device

Corrupt drivers or wireless driver issues is another reason why you may not be able to see any Wi-Fi not working networks or have trouble detecting your wireless card. Make sure you don't have any driver issues by following the steps below.

Remove the device and let Windows detect the Wi-Fi card again

Open Windows Device Manager.

In Device Manager, expand the Network adapters section to view all network devices.

Highlight your Wi-Fi or wireless network adapter and press the Delete key to remove the device. If there is a check box to uninstall the drivers, leave it unchecked for now.

Once the device is removed, close all windows, restart the computer, and let Windows detect and reinstall the network card.

If letting Windows detect and reinstall the wireless card doesn't solve your problem, it may be the drivers themselves. Follow the steps below to reinstall the network card and wireless drivers.

Reinstall the latest network drivers

Find and download the network drivers for your network adapter. If possible, we recommend obtaining the drivers directly from the manufacturer (for example, Dell, HP, Linksys, or Netgear).
