Thats what was happening with me primarily, ask you're phone company for a kit that gives a direct line to the broadband modem (Its just replacing the front of you're main phone socket so it has 2 inputs and wire the modem in directly to the socket, it gets rid of all the broadband filters and this does it for you, kit has a 30 metre lead and all the extra bits you need including instructions). If you are on BT they should give it to you free, they did give us it free and its dead easy to fit, now I have no probs at all with the broadband.
