When DSL was first installed in the house, the installer put a separate jack in the wall in a downstairs home office which is where it's been for five years now.
Now we want to relocate the office (including PC) to an upstairs room. Was I told correctly that the DSL modem can be plugged into any phone jack in the house? (There is a jack in the upstairs room already) Do I need to purchase a filter or any other sort of hardware to attach to the line? (I do not want to pull wires through the wall unless there is no way to avoid it)
Would appreciate a pointer to any websites or FAQ's that might help.
