I am just confused with so many profession words:modern router central fliter.........i have install a home phone from telstra and i have a computer with wareless internet card inside(i do not know how to express the very equipment in english)
what else do i need to finish a installation of the broadband internet? There are 4 computers in my unit, i heard there is a device which could combine modern and router together, is that what i need? do i still need a central fliter which the tpg suggest?

Help please
