Master socket

Thanks I'll try that. I did buy a new ADSL filter that didn't work. I'll try the BT431.

Is the socket the router works in a filtered socket, i.e does it have 2 sockets, one for phone and one for broadband? If so, it is very likely the other socket is wired from the filtered side.

You didn't mention that! Unlikely that two filters, (one new) are going to be faulty.

More likely the way that the sockets are wired, as @licquorice  mentioned.

This is where the phone plugged into in the hall. Presumably the master socket. This is where I want to connect my router as its central and will provide a better signal. I live in a flat. It won't plug directly in due to shape of socket so I bought a new filter. But the router didn't connect. I will post picture two below to show where the router is currently connected.

 this is where the router is currently connected in my bedroom. This was set up 20 plus years ago. I just want to connect the router to the socket in the hall where the telephone was connected.

does you phone still work in downstairs socket?  if downstairs socket was the original place for the master socket then openreach have rewired it to make upstairs socket the master and it would help if you removed front of downstairs socket and posted photo

You basically have two master sockets ,this isn’t really a good idea but it’s not uncommon , the upstairs master socket has two ports , the lower one for a phone that presumably you never used , and the upper one is pre filtered so the cable from your router can plug directly into it without a separate ‘block’ type filter .
To use the downstairs master socket for the router , you need a separate block type ADSL / VDSL filter ,  plugged into the single (only) port of the master socket  , the  block filter has two ports , one for the router and one for the phone , the one for the phone is now redundant as your phone connects to the router not the filter ….no reason why that shouldn’t work , if you have tried a block ADSL filter like this and the router didn’t connect, obtain a new filter and try again, if that doesn’t work , the ground floor master socket has a removable lower section held in by two screws , remove the lower section, behind it is a test socket , plug the ADSL filter into the test socket and try that , removing the lower section and using the test socket the upstairs socket should be completely disconnected

As I keep saying, your downstairs socket is wired from the filtered side of the master socket upstairs.

Move the 2 wires that are in slots 2&5 of the removable faceplate and transfer them to the data extension terminals instead.

@iniltous  I suspect the OP has only one master socket ( the filtered one) and the downstairs one is backwired from the filtered terminals.

[iniltous]

Yep , I think you are correct, the upstairs is the ‘proper’ master and the downstairs run as an filtered extension, hence why the downstairs socket is not usable ( currently ) for the router , with or without block filter ….hats off to the BT tech that did this  for doing it properly , OP needs a little adjustment to get it working as they want
