So I just got service from my new ISP setup today, and I can get Firefox to get online fine, but neither safari or itunes will. The modem's integrated with a wireless router and it's made by 2Wire. it's a WEP network with a password. everything looks connected, i ran the network diagnostic tool and it says everything's fine. even weirder, this problem is only happening on my macbook. on my mac pro everything's working fine. any ideas? Thanks.
