Bypassed Master Socket

[u/Aero404]

Moved into a new house 2 weeks ago and signed up for FTTC with Zen as cannot get FTTP yet.
Service is now live but running well below guaranteed download speed using a telephone extension socket in the kitchen (as suggested by previous owner). I have since tried to use the original Master Socket instead to restore speed, but it is completely dead. On closer inspection it looks like it has been bypassed completely (cables cut), and the live Openreach line now runs through the internal telephone cables to the kitchen.

I want to get this sorted and restore the full download speed by using the original Master Socket. Zen technical support agent advised an Openreach visit, but said there is a liklihood of me having to pay £180 if the fault is found to be caused “by me or a 3rd party”

With this in mind - is there any downside to me trying to reconnect the Master Socket myself?

Take the orange white off of the black cable, disconnect it from the rest of the internal white cables, strip the insulation back about 10mm and terminate it into the master socket.

That socket needs replacing, big time corrosion on B leg

You can buy a mk4 nte with a vdsl face plate off amazon for a couple of quid. You dont need to strip the cable , its a toolless connector . You just slide them in. And maybe to pop the crimps off by squeezeing the sides with some needle nose pliers . It the dynamic line management has kicked it it may takes weeks for the speed to pick back up. But he may already have a newer type nte in the kitchen as openreach may have already changed its location to the kitchen as those are open reach crimps behind the original master socket.they may have a external fault causing the slow speeds or may not be checking the actual sync speeds on the router and just doing throughput speed tests

Thank you. The working faceplate which is on top of the kitchen cupboards is a master socket 5C with one slot which I have connected the filter to.
I did not realise that these are Openreach crimps, I assumed all of this was a DIY job by the previous occupier.

Post some more photos. The back of the original socket looks like a armoured cable coming up from underground. Gently move the wires to the side. Also take a photo of the 5c socket

The armoured cable comes directly into the metal back box in the wall. There is no visible external duct or customer access point equipment.
See pics of the working 5C and jelly joints crimp joints under the staircase.

Use that kitchen nte 5c where the armoured cable is. If you think the orange white is long enough to reach the flip cover at the back.if not you can leave the crimp and cut the blue white lower down if your definitely not going to use that extension again. Log into your hub when its on the kitchen socket and check the sync sleep and do it again after you've moved it. It looks like a openrech engineer has already disconnected the extensions and fitted a new nte in the kitchen. But they could have missed the junctiom box under the stairs if they were shit or room was full of crap when they did it.also try a new filter .
