How about expanding this so we can understand what you really mean.
As the OP pointed out in his follow-up there is Bridged/DHCP and PPPoE
ADSL, and you seem to lumped them together. Most ISPs are now using
PPPoE because it's to their advantage to do so; it offers little,
if any, benefit to the consumer. And I have no idea what "windows
mode" means - but then I don't do Windows.

Maybe you could point us toward what part(s) can be configured to
help with this?
