Website Entered Incorrectly

• If you are able to browse the Web but cannot ping a website, you should first confirm that you entered the website's name correctly. If you mistype a URL in your Web browser, the browser may have the ability to redirect you to the correct site. A ping only works, however, when the address of the remote server is entered correctly. To ping a server, open the Windows command prompt by typing "cmd" in the search field at the bottom of the Start menu and pressing "Enter." Type the ping command at the command prompt. Two examples of valid ping commands are "Ping google.com" and "ping 192.168.0.1."
  
  

Website Issue

• Most websites respond to ping requests. It's possible to configure a server to ignore pings, however, and website operators may do this as a security measure or to conserve a server's resources for more important traffic. If you are unable to ping one website, but can easily ping others, the site may prove blocked. If you are also unable to view the site in your browser, the remote server may be down.
  
  

Network or Internet Connectivity Issue

• If you are unable to ping any website or browse the Web, a connectivity issue may be preventing your computer from reaching the Internet. Check to confirm that your wireless adapter is getting a signal from your router or that the cable connection from your computer to your router or broadband modem is secure. Unplug the power cables from your router and broadband modem for 60 seconds, then replace them. If you are still unable to ping any sites or browse the Web, contact your Internet Service Provider (ISP) for assistance.
  
  

DNS Issue

• On the Internet, a Domain Name Server (DNS) is a computer that essentially acts as a phone book, linking a website's name -- such as google.com -- to its IP address, such as 74.125.224.144. Your ISP has at least one DNS, and most likely has a second one that takes its place if the primary server experiences a problem. In the rare event that both DNS servers go down, your computer will be unable to perform the lookups necessary to link website names to their IP addresses. You'll be unable to ping a website using its domain name, but can still ping IP addresses. You can utilize a free public DNS to circumvent this issue until your ISP resolves the problem.
