Unable to connect to the Internet

I just tried connecting to the internet and got the following message:

Unable to connect to the Internet

Google Chrome can't display the webpage because your computer isn't connected to the Internet.

You can try to diagnose the problem by taking the following steps:

Go to Start > Control Panel > Network and Internet > Network and Sharing Center > Troubleshoot Problems (at the bottom) > Internet Connections.
Error 106 (net::ERR_INTERNET_DISCONNECTED): The Internet connection has been lost.

I had already

1. Rebooted my cable modem
2. Rebooted my laptop

But I still was getting the error and doing the following two steps fixed the problem in the past.

Then it occurs to me that I didn't plug the network cable into the laptop. Problem solved.

The error message should have said the top 3 things to do. Numbers 1 and 2 are listed above and number 3 is
    3. Make sure computer is plugged into the network.
