Phone line - whose responsibility?

oldbikebloke

i have lived with exactly your physical limitations for years.
my router is plugged into an extension lead run across the hallway and my PC is hardwired to the router via Cat5e cable which also runs across the hallway 
yes it is unsightly because I have rugs down to reduce the trip hazard, but it is the solution  

i do not need wifi - i want a 100% reliable signal at the best speed I can get, which isn't by wifi

We're very happy to buy a new phone extension cable ourselves and just run it internally across the house, not fixing it down. But should we be asking/expecting the LL to replace/fix the existing extension cable? 

This probably your best option, but you would have to buy the cable yourself I'd have thought. RJ11 phone cable is thinner than RJ45 network cable, so it's easier to route and work with. This is pretty much what you have now, but the RJ11 cable has been put outside and degraded in the weather. If you run it inside, you should be fine.

You can use powerline adapters if you want an alternative to wifi, but I work in IT so the speed of them annoys me. I think they're fine for the average user, but I keep all my media on a shared network drive so I set mine up a similar way as you'd find in a small office. Double network sockets in every room, they all go down to a network switch in the cupboard under the stairs where the network drive is and it's gigabit throughout the house via cable, but I use it for streaming and to transfer large amounts of data quickly which most people don't need to do.

Once you've got the router connected with a decent phone cable, you should get a stable internet connection from outside. You might just want to keep the wifi or use powerline adapters to cable devices in. It all depends what you need it for and how fast your internal network needs to be.
