In trying to resolve a speed issue with my ISP I've had to chop and
change between old and new routers. Whilst I can get on line with IE
via my broadband connection I can't get on line with OE. Whenever I
try to do anything i.e. Tools Get Next 300 Messages a dial up
connection box appears. With an always on BB connection I have no need
to dial up.

How do I re-jig OE such that it uses the same always on BB connection
as IE?

I appreciate this is probably very simple, but it's something I do
once in a blue moon, so am apt to forget between times.
