can't connect to the internet using a pppoe(user name& password) mandriva2009
 

It's my first time using linux mandriva 2009, i connect to the internet by a speed touch modem, through a pppoe connection using a user name and password, but i can't seem to connect the the internet, evethough i made the connection and still can't connect, the ethernet connection is connected, but the pppoe is not.... i get the message "no medium found" don't know if that is related to this problem???? please help, after i do this i can DUMP Windows for ever....

what are you using to connect?
errormessages?
try raspppoe

well first forgive my ignorance in linux, well i'm using ethernet, to connect directly to the internet, through a user&pass,and a speed touch modem,if that's ur ques. as i mentioned, but i get the error message "verify your configuration in linux mandriva control center"
i deleted pppoe connection a zillion times and tried making the connection, but still can't connect to the internet, the ethernet connection is working but the pppoe connection isn't... still got no clue what is wrong... how can i use raspppoe?! thanx for taking the time to help:) i tried in windows everything is ok there....!!
