Hmm, getting more and more confused.

I went in to PB Tech yesterday and explained the situation.

They told me to buy the following (see image).

- 10m CAT6 cable

- RJ45 8 Conductor 2 way joiner (2 x sockets)

- RJ12 to RJ45 cable.

Plug one end of CAT6 cable into router.

Other end into the RJ45 2 way joiner.

Then RJ45 into one end and RJ12 to the phone socket.

So will this not work?

Also, can I expect the ISP to come out and do this free of charge???

No, because dsl interface on router is not RJ45.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

But the RJ45 cable doesn't go into the router.

Quote "Plug one end of CAT6 cable into router." cat6 has RJ45 plugs on each end. Wall phone socket is BT. Router dsl interface socket is RJ11.

Ah, I see.
Bugger, so is there a converter, which will allow me to plug it in?
I was told that CAT6 and ethernet cables are the same (at PB Tech). So I guess ethernet cables hasn't got RJ45 plugs?

They are the same and have RJ45 plugs. You aren't dealing with Ethernet though so I'm not sure what your point is.

You need another RJ45 to RJ45 joiner and RJ45 to RJ12 cable + an RJ11/12 to BT adapter.

I think I get it now. Router has RJ11, right? So I would need a RJ11 to RJ45 converter? RJ11 cable into the router and other end into RJ45 converter. Then other end of converter has CAT6 cable?
(Sorry, on very deep water here, hence the questions)

router dsl interface (RJ11 socket) <---> (rj11 plug) adapter cable (RJ45 plug) <----> (RJ45 socket) Joiner (RJ45 socket) <---> (RJ45 plug) cat6 cable (Rj45 plug) <---> (RJ45 socket) Joiner (RJ45 socket) <---> (RJ45 plug) adapter cable (RJ11 plug) <---> (RJ11 socket) adapter (BT plug) <---> (BT socket) Wall.

Strange mdf, that links works if you copy paste it, but not clicking it. @freitasm is the affiliate linking doing something strange here?

That's an Amazon UK link, the affiliate script rewrites it as Amazon US. Sorry...

You don't need a converter. An RJ11 plug will fit in an RJ45 socket fine. It's still a total kludge, but you would have an RJ11-RJ11 cable at either end. In between would be an ethernet joiner at each end of an ethernet cable (basically to make the male RJ45 plug into a female socket).

All those joins aren't ideal, and the RJ11 cables will be untwisted so you want those as short as possible.

But what you probably need is a networking tech to come and sort it out properly, probably with a new jackpoint in a decent location and a master filter. You'll likely get better results and future proof yourself against any future technology upgrades.

OK, I might have to call someone to do this, as it indeed does sound like it's the way forward, instead of all the mocking around with the cabling.

Would it be an IT tech or just a sparkie?

(Can you recommend anyone - it's in Army Bay, Whangaparaoa)

Some sparkles are good at this stuff. But only some. Where are you based?

Also, very very rough ballpark figure for them to do this? Have you got an idea?

Just light up the @coffeebaron signal!

He has (had?) a promotion for a $150 master filter install for GZ members. There might be travel and some additional costs on top of that if he ends up moving the jackpoint though.

Thanks. Much appreciated. Will get in touch with him.
