There are 3x BT sockets in the house - 1 behind the TV (lounge), another in the lounge and 1 upstairs.

 

Router is directly into socket behind TV, main phone is in the other in the lounge and we have an extension phone upstairs (there is also another extension phone in the kitchen but not on a socket)

 

When we have phone call, when the call is finished the internet signal drops/cuts out? Socket behind TV has a filter BUT when I put a filter on the other socket in the lounge the phone doesn't get a line?

 

Everything works but just that the signal drops?

 

Any ideas?

Sounds like a faulty microfilter.

 

There should be one on each phone socket.

If you're on Sky, they should send some out if you ask

Do they / can they fail? I've tried 3 different filters on the phone line socket - is that one or the router socket which has failed do you think?

 

Think it has only recently started doing it.

is your router plugged into the main socket not the extensions?

Yep filters do fail, depending on the quality. As they're usually throw-away types bundled free, assume they'll fail

 

I'm going to say it's either filter related, or a fault with your internal phone wiring.

is your router plugged into the main socket not the extensions?

 

This I am not sure of Lee - the builders put in a "hub" behind where the TV goes and it contains 4x power sockets, phone line socket, aerial point and Sky TV inputs, all packed together to make installation easy. But then there is another phone line socket at the opposite end of the room. So not sure - it could be?

the 'main' socket should have a lower cover on it.

This is the socket your router should be connected to.

You need to test it with a known good filter in the test socked - which is behind that removable lower half of the master (you will see what I mean).

 

There is also a fault know as a whetting fault, where the current that flows when the phone is up, causes a bad connection to reduce resistance and allow the ADSL and voice connection to be made. My Father-In-Law had that once, the internet would only work when he had the phone off-hook. Put the phone down and the ADSL signal would also drop.

Not sure how to check to be honest - although not exactly the same, our "hub" behind in the corner is like this:

As above really - need to try and find out whether that is the master or whether the other socket is the master. I can take the cover off the other one.

those appear to be network sockets, not phone sockets.

It's not the "actual" unit we have but just gives you an idea

 

They are definitely not network sockets.

Another vote for duff microfilter, the passive ones that come free with routers are rubbish. I had an issue with the internet dropping, replaced the filter with an active one that cost me about a tenner and the problem was cured instantly.

 

Something like this should work.

If it's a new build or fairly modern, chances are the BT master will be by the front door? Do you have a point in the hall?

No, no point in the hall.

Ah OK. Play hunt the Master Socket then

It could be any of the micro filters as well, not necessarily the one the router is connected to.

That hub looks like it has a filter built in?

The main socket could be any of the sockets in you house.   If you call for an engineer fix, Openreach will NOT open up those multiway faceplates, they are deemed as dangerous as the mains wiring and phone wiring are not isolated from each other. You should see the developer for advice.   If an Openreach engineer does attend they will do no more than fit an NTE somewhere near where the phone line enters your house.  You may have an external test point outside the house in a grey box in which case you can test the line there yourself.

You could go round each socket and disconnected the wire on terminal 3, this is the bell wire and often causes line imbalance.  If you have  newish phones or any cordless phones it won't stop them ringing as they are now are 2 wire working.

 

If you need further help, PM me.

tried the router power supply?

Main trouble with your internet feed is that your dealing with 3 companies.

BT and Openreach (which is separate company) and to top-it-up Sky..

Sky just's taps into BT lines as BT do all the graft getting a telephone line to you..

Well there is only 1 microfilter attached where the router is - plugging in a microfilter onany of the other sockets cuts off the line.

There is a grey point outside the house with a line going into it - looks like some form of BT thingy! NTE?

I may just do that - I'm going to try a new microfilter on the internet line socket and see what happens.

In what sense? Could that be the issue?

Exactly - it's a battle enough trying to get any sense of out Sky let alone getting an engineer booked. Am considering switching to BT for TV, phone and fibre anyway.

This is an External NTE you can test it here https://www.google.co.uk/search?q=external+nte&biw=1242&bih=592&tbm=isch&imgil=AYzf07zw-PSbWM%253A%253Bhttps%253A%252F%252Fencrypted-tbn3.gstatic.com%252Fimages%253Fq%253Dtbn%253AANd9GcQThQJ6jbERZPvFvyrGpsfsYAl18NuZkIcg2Xa_98syPywrLKxQeg%253B976%253B748%253BIULvG_uRj1-7lM%253Bhttp%25253A%25252F%25252Fwww.kitz.co.uk%25252Fadsl%25252Fbtsockets.htm&source=iu&usg=__rJjr6n2Y4iFozy7jKlaGKCPq2zI%3D&sa=X&ei=s1B7U4P2GZKP4gSWqIHQDA&sqi=2&ved=0CC4Q9QEwAA#facrc=_&imgrc=AYzf07zw-PSbWM%253A%3BIULvG_uRj1-7lM%3Bhttp%253A%252F%252Fwww.kitz.co.uk%252Fadsl%252Fimages%252Fphone%252Fexternal_NTE_2.jpg%3Bhttp%253A%252F%252Fwww.kitz.co.uk%252Fadsl%252Fbtsockets.htm%3B976%3B748       Any other type of box is not an NTE.  

 

I'm sure you can work out the cable going away from the house, it's only 2 wires. Connect your filter/router/phone and see if the fault persists.

There should be a microfilter on every phone attached to a socket.

Get you - yes we have one of these. I'm off Friday so may have to do some testing.

Yes, correct. But this is the issue. Alongside the internet signal dropping after the phone is used, if I connect a filter to the other socket in the lounge I get no line at all (from that socket).

I could be way off the mark here Coops but how many phones do you have connected and what is their REN (Ringer Equivalence Number)
