Default Connection

Using Vista home on a new HP PC. After connecting to DSL broadband it works
fine. Using a wireless router. 2 HP PC's are using a wireless USB adapter.

But when both PC's are turned off, then restarted after a lightening storm,
they both load up to a default DIAL Up connection.

It there a way to make the Always on DSL broadband connection load up at
startup ?

Thanks from New Orleans
