Ethernet wall ports not working

I think that would suggest each port is on an entirely different cable.

If you have an ethernet patch lead handy, try the tester on that to see what a working cable looks like.

Thanks, will give that a go. Another stupid question, should I not have a master socket somewhere? The socket in the cupboard with modem doesn't look like a master socket - unless my modem is my "master" - p.s - IT is a totally different language to me .. just trying to find solutions for my gaming not to lag which it does via wi fi

A new build specified for FTTP won't have a 'master socket': that's a concept from copper telephony and then copper-based broadband.

I’ve seen this setup a few times in new builds.

The phone socket is provided on the, (now obsolete), notion that the VoIP phone service is delivered through the ONT.  It was for a time but now it is provided through the ISP router instead.  The socket allowed the ONT to connect to the phone extension wiring.  Unfortunately, this means it is unlikely to be suitable for ethernet, even if they have used 4 pair cable.

The idea seems to have been that no one needs ethernet cabling as they all use Wi-Fi today, so we can save a bit of money and not put in network cabling.  Really annoying, naïve thinking but that’s developers for you.

Edit: Oh, and I forgot to add, modern plasterboard tends to be foil backed, so good luck with the Wi-Fi.

Re done the wiring to Ethernet socket, run the cable tester again, skips no. 3 and 6 which is the green cable pair , they're definately in there securely.. so now even more confused as cables definately talking to each other each end.

I’d punch them again.  Sometimes they don’t go all the way down the first time.  3 & 6 are essential, by the way, even for 100Mb/s TX wiring, which used to just require 1, 2, 3 & 6

Actually, thinking about it….if they are wired as phone sockets they can only use a maximum of 6 wires.  Also, as phone cabling they will be daisy chained.  The implication of your two missing wires is that there is another phone socket somewhere between the two.

[Kinga1]

There's another socket in the bedroom, so... if I rewire that one too all 6 should work for Ethernet? 

[StuXxxxx]

Ethernet doesn’t work as daisy chaining.  It’s point to point star wiring.  So a better plan might be to replace the offending socket with double RJ45s.  Connect one cable to each then link the two sockets together with a short patch lead.

I think I give up tbh with you all, got one socket re wired as Ethernet port one as phone still and I can't be buying more things to get this thing bloody going.. will just stick to wi fi ... thanks all for help and advice
