It's frowned upon, but I'm sure you'll be cut some slack being a noobie.
Having read the other thread, I'd guess you have a duff Hub5, since it won't connect to ADSL whereas the Hub 3 will.

It should be apparent when the connection to FTTC has been made, you'll see the 3 drop out, then not come back.
