I'd like to know if anyone else has had this problem with the 17" PB? Occasionally, when using airport on a dial up connection, an error message comes back, "Username and Password Incorrect." Then, when I try to reconnect I get the same reaction but instead of the modem resetting quickly it never resets at all and the modem status bar in the menu bar just keep saying "Waiting for Modem to Reset." Any thoughts?
