I was wondering if some of you could sense check my thinking with an issue I have running VDSL from an extension socket.
My master socket is located right beside where I sleep so when my router is plugged in here (vodafone) Its around 1m from my head. Id like to move it as not happy at having WIFI blasting me from this distance all night!
I've followed some guides, disconnected all other internal wiring from the extensions (i have 3 wired in serial) and used the existing wiring to the nearest extension in the living room to connect the DSL extension from the MK3 faceplate on the master socket, to pins 4 & 5 on a new RJ45 face plate in the living room.
Speed at master socket is 70meg down, 20 meg up
Speed at extension varies between 50 and 60 down, but only 11.5meg up
I believe extension wiring isnt shielded particularly well, and is likely picking up interference thats reducing the sync speed. The number of FEC errors is extremely high when connected to the extension, and CRC errors are higher (both upstream) - FEC as an example i've getting about 1000 per second as far as i can see when the router stats refresh. Downstream is not too bad.
Im thinking that if i replace this cable with a better quality shielded cable it will likely result in speeds very close to what I am getting at the master socket currently.
Im not 100% sure on what the best cable would be, double shielded with the pair and the cable braided and foiled would be my best guess from what i've read so far.
I have a 5m length of this cable that ive ran from the modem to master socket with no drop in sync speed. To put a similar cable via the same route will likely involve 15-20m of cable and a bit of patience.
Am I right in thinking that the existing cable is the likely issue and that better quality cable will help? Am I missing something else that could be causing the issue?
Any thoughts and experience with this would be appreciated before I embark on buying double shielded cable, hard wiring one end to the VDSL face plate and trying to route the new cable via the same route as the existing!
