I have received the cable to connect my landline phone to my router. This is not possible. MY TV is in the front room, my router is upstairs in the rear of the house and my phone in the hallway near the front door where it is accessible to the whole house. Is this something an engineer could fix or do I have to abandon the landline. I am not prepared to move the landline. The 3 computers upstairs are desktops with no wireless cards, all connected by ethernet. If I have the router moved downstairs it would have to go beside the TV. Could I connect the upstairs computers using HomePlugs or would I need to fit wireless cards to the desktops, I expect that would mean having wireless boosters.
Grateful for any thoughts and advice.
