NO connection to Google or Yahoo. [Closed]


I cannot connect to Google or Yahoo. I use 10.5.8 Leopard. Not Snow Leopard. I use verse ATT for a modem at home. However, if I carry ibook to work I have no problem. Crazy. I think it is a firewall problem but now sure. I have looked for things like peer guardian and spyware on my ibook but they do not exist.
