How to Repair a Network Connection in Windows 7

Windows 7 is designed for networking and working with the internet, so when your network connection isn’t working, it can be particularly frustrating. Fortunately, Windows 7 comes with a built-in troubleshooter that you can use to repair a broken network connection.

1. Choose Start→Control Panel→Network and Internet. Then click the Network and Sharing Center link.

2. Click the Fix a Network Problem link.

   

   The link pulls you straight into the Control Panel’s Troubleshooting guide for the network.

3. Click the link for the type of network connection that has been lost.

   There are several different troubleshooters available:

   • Internet Connections: When you can’t connect to the Internet or to a particular Web site

   • Connection to a Shared Folder: When you can’t connect to a file or folder that you thought was shared

   • HomeGroup: When you’re unable to view files or computers in your homegroup

   • Network Adapter: When you’re unable to communicate with your router or modem

   • Incoming Connections to This Computer: When you’re unable to let other computers in your network communicate with your PC

4. Work your way through the troubleshooting guide.

   

   Windows 7 will ask you a series of questions. As you respond, you’ll get closer and closer to the answer. If Windows suggests an action you must perform, such as plugging in a cable, do so.

5. When the solution is found, close the Network troubleshooting guide.

Sometimes the troubleshooter isn't able to correct the problem. In that case, it’s best to delete the connection and just create it again by clicking the Set up a New Connection or Network link in the Network and Sharing Center window and entering the correct settings.
