How do I fix a network adapter problem?

If you can't connect to a network, there might be a problem with your network adapter, the piece of hardware that makes it possible for your PC to connect to a network.
First, try using the Network Adapter troubleshooter to automatically find and fix some problems. This troubleshooter will disable and re-enable the adapter and try some other common repairs:

• Open the Network Adapter troubleshooter by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering troubleshooting in the search box, and then tapping or clicking Troubleshooting. Tap or click Network and Internet, tap or click Network Adapter, and follow the instructions on your screen.
