Can I use my old BT dsl cable to use on my new NOW wifi Router? I have been told it has to be a now cable.
Would have thought as long as the cable isn't excessive in length then any RJ11 to RJ11 cable should work.
Give it a try when your NOW Broadband activation goes live.
Some further information in this linked thread below discussing the RJ11 cable between the BT Master socket and the NOW Hub Router.
