After registering our new AT&T dsl service on a windows machine, we have connection. when I try to set up my iMac using PPPoE, (System preferences>Network) I go through the prompts to set up typing in the account name (ATT user/member ID name) and the password I set up to register. I have a 6-digit alphanumeric password. I type it in but when I click the "Apply Now" button, the password changes to 8 digits. This occurs on my desktop IMAC and my Mac Notebook. Anyone have any ideas as to why it inserts 8-digits in the password field?
