I have an iMac with airport card, and a Powerbook with airport card. The iMac is connected to the internet via broadband, and is sharing its connection - via airport - with the Powerbook. No problem.
However, when I try to check my e-mail on the PB, problem. Nothing happens. It's not just Entourage being screwy. While I can access my university webmail site on the iMac, the PB won't load it. Same goes for my Gmail account.
This is rather frustrating. Does anyone have any idea how to fix?
