How to Fix Your Windows 7 Network

Setting up and maintaining your home PC network is easier than ever before with Windows 7--but that's not saying much. Many networking issues still aren't easily fixed from Windows 7's control panels. That's why we've compiled a list of common networking problems and their quick fixes.

Reset Your IP Address

If your system's connection to a network is unreliable, or you're getting IP address conflict error messages, try renewing your IP address. First, click on the Start button, navigate to the Command Prompt (Start Menu, Applications, Accessories, Command Prompt), right-click it, and select Run as Administrator from the menu. Then type ipconfig /renew, and press Enter. That should do it.

Flush Your DNS Cache

Whenever you type a URL into a Web browser, your PC asks your domain name service server (DNS server) to translate that URL into an IP address, and caches that information. That cache can occasionally become outdated or corrupt, which can cause Internet connection problems. To clear your DNS cache, open the Command Prompt with Run as Administrator, type ipconfig /flushdns, and press Enter.
