This problem is usually caused by manually defined DNS on your wireless connection. 

To remove the manually defined DNS settings for a connection, follow the instructions for your platform.

Windows Vista/Windows 7:

  1. Open Network Connections by clicking the Start button , clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking manage network connections.
  2. Right-click the connection that you want to change, and then click Properties.   If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  3. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
  4. To obtain a DNS server address automatically, click Obtain DNS server address automatically, and then click OK.
  5. Retry your connection.

Mac OS X:

  1. Open System Preferences, located under the apple menu.
  2. Under Internet and Wireless, select Network.
  3. Click either Wi-Fi or Airport, whichever you are using, and then click the button labeled Advanced.
  4. Click the DNS tab, and then, in the box labeled DNS Servers, see if there are any entries in black text, rather than gray text. If so, click on the black entries, and click the minus icon at the bottom of the box for each one until the box is empty. It should then fill in three gray entries automatically.
  5. Retry your connection.
