Help connecting wall socket

[u/born-_-stubborn]

A little help from those more knowledgeable than me.

I'm replacing the wall socket for our Telstra home wifi and could anyone assist me in which two connections to use?

First pic is the existing and second pic is the replacement socket.

Thanks in advance.

Pins 4 and 5. If you look closely you will see the same numbers on the old socket.

Update - My god man you were right!! You may not realise this but you've save my life/sanity and upon the return from the shops of my wife and kids I'll no doubt be showered in praise and affection. Thank you good sir 🙏

So pins 4 and 5 on the same side? Does it matter which of the 4s or 5s?

One wire on a 4 and the other on a 5. Doesn't matter which ones because they are commoned up inside the jack to allow parallel extensions which you wouldn't use on VDSL.

Your old socket was the same but just had the numbers in different places.

Get a small flat head screwdriver and jam the solid core wire into the groove. Make sure it’s a flathead and not a proper IDC tool.

Slam that screwdriver in hard. Make sure
the socket has tool marks.

Don’t worry about the corrosion on the contacts, gives you a slight speed boost.

Edit:

-That appears to be a “lead-in” cable that requires a licensed person to legally work on this socket.

-The whole socket needs replacing. Bunnings sell the plate and socket for around $25.

-There is a special punch down tool for this type of connection. You can also purchase a cheap one from Bunnings also.

You’re probably better off calling a third party telecommunications tech.
They can replace the socket and perform continuity and insulation tests between your socket and the NBN demarcation point.

A good tech will verify this point for you.
Invaluable when dealing with NBN. They will inevitably blame your internal wiring for any faults you report.

Corrosion gives a speed boost? That’s sarcastic or is there some positive benefit from increased resistance in the line?

[u/MyNobbyBreakwall → u/IanLx]

Definitely sarcastic. No speed boost from corrosion. Resistance in the joints of electrical signals is pretty much always undesirable.

There's only a handful of cases where I can think it's a good thing but even then you do it with a dedicated resistor (E.g. modbus) and not though corrosion lol.
