have the same google.com problem
Hi there, I have the exact same problem on my macbook! I was researching google(on my pc computer) and found this article. It seems to be a DNS problem in my network settings. I tried typing google's IP address and it appeared! I have included the link to the web page at the bottom and pasted his response.
hope this helps.
When you're in a situation where you can connect to a network, but there's the appearance that you can't connect to the internet, the very first thing to check is that you REALLY can't connect to the internet, or if you just have a DNS problem.
DNS is the service that converts domain names (for example forums.macosxhints.com) to the IP addresses that are actually used on the internet (for example 129.250.134.26).
A common situation is that you actually DO have a connection to the internet, but because there's some problem with DNS, all of the domain names that people regularly use are not being translated to IP addresses.
It is quite easy to check this: just try using an IP address instead of a domain name. So, for example, you can enter
http://64.233.167.99 into the URL address field of your browser of choice (like Safari or Firefox). If that IP address brings up Google, even though entering
http://google.com does NOT bring up Google, that means that the actual problem is with DNS, not with the internet connection.
If that is the real problem, then enter a DNS server explicitly into System Preferences > Network > Show: your network interface, such as Airport > TCP/IP tab > DNS Servers. You can get the IP address of DNS servers from your internet service provider, or there are lists online of public DNS servers.
