With the new BT Smart Hub 2, I will have to re-wire the connection between the socket and the router / hub, and getting stuck at how best to do it.
The socket is downstairs, in the dining room; quite happy to have it there because that's where the phone is
The router is currently in the study, because that's where the main PC is - and that's where I'm likely to place the new Smart Hub
Currently, there's a telephone line between the socket and the router that goes around the skirting boards of rooms, stairs, and more rooms. I tried to stick it under the carpet edge where I could, but it inevitably gets pulled out here and there. The new wiring would need to be the RJ-11 cable which is slightly larger, so doing the same is less than ideal.
To complicate things, I rent the house so can't really drill holes in the walls and ceilings.
I also try to minimise Wi-Fi use, at least wiring up the PC.
So I have been thinking about options: - put the RJ-11 cable the same way - use powerline adaptors of some shape; I think there are separate circuit breakers for upstairs and downstairs circuits which make it less than ideal, not to mention that I'm not even sure if I can run the "before-the-router" signal via the mains cable.
