I currently have phone lines in my house which are at either end. The issue with this is that the wiring is old and slows down my VDSL connection, but mainly, when I am at the opposite end of the house to my wireless router, signal strength is poor!

My solution, install a RJ11 socket in the middle of the house.

The good news is, there is a blank wall plate in the middle of the house. On the other side of this are phone cables, because the D-mark point is directly on the other side of this. (why there was never a phone jack in this bedroom is beyond me)

I want to do it myself.

Does anyone know which wires need to go into the RJ11 socket for VDSL. (I have naked broadband, no phone line)

Thanks in advance.

They will go into 3 and 4 of the socket. you have 2 incoming cables, so it should be the black and yellow of one of them, no idea what that speaker cable looking cable is doing in there.

Thanks for that. Does it matter which way around they go?

That grey cable might be the old early 1980s 4 pair cable. 4 conductors in each each sheath.

No, polarity doesn't matter for DSL or normal telephones.

I've not seen those sherbert straws used as joiners before either. Was that an 80s thing too?

had speaker like cable in my old place, took my 70/10 line down to struggling to manage a sync and hitting 4/2ish when it did..

ild be tempted to run a fresh wire and use a master filter assuming your on a clothed connection there...

Also remember wireless is a conveyance feature, and you shouldn't expect full performance over it.

Copper twisted together inside then that slides over the whole lot. You'd use a gel crimp now.

Yep, those are old twist joint sleeves, I've run across them twice looking at old joint pillars. As for the internal wiring, you come across that stuff a bit too often, it's not solid core, and it's not very good. Replace it where you can, I reckon, it'll do your broadband a world of good.

Speaker wire totally kills VDSL2, and had a pretty significant impact on ADSL as well due to the fact it's not twisted.

You'll potentially need some scotchloks and jumper cable to punch down directly into the RJ11 as the AWG of the outdoor cable is normally too thick.

Is there any reason you didn't just use a RJ45 which is standard now? I haven't seen a RJ11 socket for years, and last time I did they were twice the price of a RJ45!

Often they just sheath the twisted joins with a bit of cable jacket, but doesn't prevent corrosion in my opinion. Old habits die hard tho, and some techs incorrectly twist the bare wires like that before putting on the scotchlock crimp. Really bad practice.

Time to find a new industry!

I guess the modem comes with an american RJ11 cable...

The 2 phone wires go to the blue pair on the RJ11 plug (or RJ45 for that matter). Use a tool to punch them straight into the slot, don't strip the insulation off each wire. Same for scotchloks, each wire gets inserted as is and the insulation stays on. If you don't use analogue phones then just remove the grey wires, otherwise you need a VDSL splitter and the grey wires go to the "phone" output of the splitter. If they don't fit the scotchloks then better to replace them or do the old wire twist, but make sure you use scotchlok type joiners on the splitter's DSL output because its more sensitive to having a good connection..
