i have pacbell dsl and a linksys router... my connection has been working great. first of all, don't use the enternet program that pacbell gives you. what you want to do is type in the address area in Internet Explorer,
http://192.168.1.1 then a window should pop up asking for a user name and password... leave the user name area blank and put admin for the password (note this is assuming you haven't changed the default settings). then in the router settings. you want to enable PPPoe. enter your user name for pacbell (essentially your email without the "@pacbell.net") and enter your password for your account. then apply the changes. now assuming that PPPoe option isn't in your settings, you need to upgrade your router software... just go to linksys and download the new software and then do all the stuff i said above. hope this helps ya out. if you still have trouble just message again :-)
