Many broadband access systems like ADSL and SDSL
connect to the broadband modem via a network card in
your computer. The software parts of these adapter setups
vary - some will show up in the list as a virtual adapter
with a name that identifies the connection, like "DSL Adapter",
in other cases you will just see the network card. If the
virtual broadband adapter shows up in the list you should
select it, otherwise select the network card you use to
connect to the broadband device.
