  Eveything is correct, I have 2 laptops side by side. One resolves to the net the other does not. Any ideas. I did just replace the hard drive in the one that does not resolve.

  Does your router have a limit on the number of connections allowed?

  are they trying to connect to the same IP, or are they using DHCP?
  check your network connections in the system prefs

  Also is it just in the browser, or can nothing access the net? Can iTunes, updates etc. go online?

  Have you tried just trashing the network connection/location and recreating it all again? Do you have an MAC address filtering, going on?

  Also, from the web (assuming you are using airport):

  1. Turn off Airport

  2. Leave the "Configure IPv4:" set to Using DHCP - this should be the default.

  3. On the AirPort tab in Network settings, UNCHECK " "Remember networks this computer has joined"

  4. Highlight your router in the Preferred Networks: list, and remove it (click the "-" sign under the list

  5. Apply settings

  6. turn on AirPort, Add your router if not already there, and that should do it.

  The above steps should not need to be repeated each time. Once should do it, but if not, at least it's better than restarting the router each time, which essentially has the same effect as the steps above.

  Apparently, there's a software bug whereby if the Macbook finds an available IP address on the Router, it remembers that address. That's fine except that if another device "steals" that address when the Macbook is subsequently not connected, and the "Remember networks this computer has joined" is checked, it's not smart enough to find another available IP address. Instead, it assigns some invalid address beginning with "169.".

  By leaving the "Remember networks this computer has joined" UNCHECKED, it will look for a valid available IP address on the router each time.
