Right click on network manager and edit connection. then goto dsl tab and add a new conn. give your id and password and service name( say PPPoE). Leave everything else default. Add the conn. Then activate the connection by left clicking on network manager and selecting DSL Connection 1. If it gets connected then u r on. By the way do you use proxy. -- Rangeen Basu Roy Chowdhury <a href="mailto:sherry151@gmail.com">sherry151@gmail.com</a> !!!Windows is "micro"-soft[ware]..I like bigger things!!!
