Broadband router interferes with phone

TighterThanTwoCoatsOfPain

you do only need 2 & 5.. Terminal 3 is the "ring" wire which is pretty much redundant nowadays.

The micro filters & often new phones have a Cap in them to generate the signal to make the phone ring.

You want to try disconnecting every wire except 2 & 5 from the master & extensions. Having the 3 terminal connected effectively just creates an antenna running round your house carrying interference.

I have a similar problem; it happened before with the modem supplied by tiscali and has got worse since I replaced the modem with a wireless router. Unplugging the main phone socket clears the interference for a while, then it comes back.
My computer and router are at the end of a long line of extension cables, with various doublers along the way to different phone extensions. At the moment I only have one filter, at the end of the line where the router is. Do I need more filters, (and if so, where) and will the above advice re terminals 2 and 5 work for me?
Thank you.

Expresso that post looks so arrogant... i doubt you would speak to me face to face like that so why on here.....??

Well yes I would, as you have already stated that you know virtually nothing about this subject. Would you tell a plumber how to do their job!

Now what throws me on this is that all the phones work ok until the router is started and on line? then the noise occurs... Is it simplistic to say that it cant be the cable in this instance because of that? I.E. everything is fine without the router on? I'm an electrician but this comm's stuff has me baffled.......

I dont see that i was impolite or anything in my question?

You will see i used question marks... which meant i was questioning the sentance. And you didnt qualify your expertise by saying you where an expert in the field?
So i have 3 diy / wiring manuals and i should not believe them but believe you, who i dont know at all, without question? Obviously i would question it??

Your manuals are obviously rather old then and if you had done some research on the web, you would have found that removing any wiring other than the pair on 2 & 5 can make a significant difference to broadband performance.

So, back on track... as your in the field or know about it anyways... Can you explain to me why the 3 is shown looped out from the main socket to all extensions in every manual, diy book etc i can see but not if the line is broadband enabled? Interested as to the reason.

The wire on terminal 3 fed to the extensions from the master socket provides the ringing current. On an ADSL enabled line, filters are required and if you open up one of your duff filters, you will see that they only connect to the line i.e. terminals 2 & 5. The filter then outputs ringing current to the telephone socket on that individual filter. Therefore as only the pair connected to 2 & 5 are used by ADSL filters, any other wiring simply degrades the signal to noise ratio of your line, which affects your broadband performance.

Should everyone remove this link if they get BB? Which by default means it needs re connecting if the BB service is removed?

Not everyone, only those who wish to get the best possible performance from their broadband enabled line. Although it can make a significant difference, not everone would be happy making this simple modification to their own wiring.

I am genuinely interested.

If you are genuinly interested, read this thread here from post #1046 to #1083 which illustrates the effect of removing redundant wiring.

As for my neighbours problem... all 3 of the filters sent by sky where useless. Swapped all his filters for mine and i got the crackle and he got a perfect line! Got him all new ones and all is well.... would have been better had they not supplied any at all!!!
So Fatnbald was spot on re. faulty filters out of the box.

So you have removed the niose from the line but what speed are you getting? Check here It is likely that this can be improved with the previously mentioned simple change to the wiring.

Connecting any other wires other than 2 or 5, e.g. 3 the redundant ring circuit can cause interference, as it can act as an aerial.

You could try switching 2 for 5 and 5 for 2 - sometimes they are incorrectly connected, some faceplates have the wrong badges.

ADSL nation for good filters as per other recommendations, put one on every extension / phone socket.

That is not an ideal situation! You could locate the wireless router at the master socket and connect using wireless or if you don't want to use wireless, get an Ethernet cable e.g. here of the required length to connect from the wireless router located at the master socket to your PC.

Which is fine had you said you where a BB / Phone expert. But you didnt.... And i wasnt telling you how to do anything.... i was stating that i had differing advice and basically asking you to qualify what you had said. And i still dont believe you would have retorted in that fashion face to face without such qualification.

Thankyou for the info, will take a look.... and your prob right about the manuals! Technology moves on at pace.
I was probably looking for phone extensions rather than BB extensions.. which may have helped. Anyway its sorted now.

Yes, I knew when I set it up it wasn't great, but I live in a big old terraced house with the main phone socket downstairs at the front, and the computer /router upstairs right at the back, so I couldn't think of any other way round it. I think it might have to be the wireless route as I can't see any of the cables being long enough. Thanks for the link though.

Ethernet cables can be up to 100 M (328 ft) in length. I don't think that your big old terrace house is that big!
