do you have any other service with anybody that provides a broadband service, such as sky tv, if you do then you can get offers that combine the two.

And as Ethel says if they don't provide a wireless router you can simply get your own.
Yes if you get a hub you can use it on any network, but I think you are getting your terminology mixed up, a hub is simply used to connect several computer together, I think you mean a router, but yes if you buy an ADSL router you can use it with any ADSL broadband supplier.
