I'm wondering if I can use a tp link adapter to connect the new phone line adapter as my hub 3 is upstairs and phone line is down stairs
If you are referring to a wi-fi adapter of some kind then the answer would be a no. VM expects the phone to plug into the back of the VM hub using the adapter that VM supplies as per
VM envisages that most people will be using a cordless phone setup with the cordless base station plugged into the VM hub and cordless phones used around the home as required.
Has your phone line been switched over to a connection from the VM hub as part of VM's phone switchover programme
or are you a new customer connecting for the first time?
