Q: Error message pops up saying "Network Connection could not find a PPPoe Server.

I am trying to update my wife's iBook, 2,1 for my mom to use.  It is running OS 10.6.8.  Every time I wake up the computer an error message pops up saying "Network Connection could not find a PPPoe Server." It does it periodically when the computer is on.  It will drive my mom nuts and worry her.  Can anyone help me stop this from happening?

Thanks,

KC
