I've been having a few drop-outs recently which have been diagnosed as "local" by my ISP. Apparently it dropped and re-connected 70 times overnight. From my side, I can see that when this happens, my local network is fine, it's just the modem reports it has disconnected. I think a good next step is to re-do the flaky wiring.

I have the usual BT Master socket in the hallway. An extension lead is plugged into this which runs about 7m into the understairs cupboard where I then have the usual filter and short rj11 cable to the modem.

I can just replace this with like-for-like and be more careful around bends and not squashing it under staples, but was wondering if there's any benefit in moving the filter directly to the master socket. I could then run a long twisted pair rj11 to rj11 to the understairs cupboard instead. Moving the modem to the master socket is non-trivial because there is no power socket nearby.

Is a cable like https://www.amazon.co.uk/Telephone-Extension-Broad... likely to be better at longer runs that a cable like https://www.amazon.co.uk/Telephone-Extension-Cable...

Personally, I'd go with option A, but rather than using a filter, I'd look to see if the front plate of the master socket can be replaced (doesn't need wiring if it's of a compatible type, it just plugs in) with something like https://www.ebay.co.uk/itm/221727286543

That way, you'd have no internal wiring as such, just the modem plugged directly (albeit on a fairly long cable) into the master socket.

If it's not a compatible socket that you have, everything you need is there to change the entire master socket - but Openreach probably won't be happy if you break anything whilst doing it.

Consider replacing your current master socket with an NTE5 & use CAT5e cable from there to the modem.

Agree, change the socket to the new one and ditch any other internal wiring.

I'm fairly sure it'll need a re-wire, and I'm not supposed to do that myself.



However it sounds like I'm best running cat5 cable with rj11 ends. Short term use a filter in the above socket. Maybe later when I decorate the hall, get the faceplate switched for something new with the filter built in.

If you're not keen on connecting two wires (it couldn't be much simpler - they even work either way round) then have a look in your local paper/free magazine for an ex-BT/Openreach engineer - there are lots of them doing small phone/network jobs.
