Does your connection drop every time you use the landline, regardless of outgoing or incoming calls ?
Can you hear any noise on the line, crackles or hisses during a call ?
If the line is dropping every time the landline is used, it could be either a faulty faceplate, or a corroded/damaged joint/cable on your line somewhere.
Possibly an HR ( High Resistance ) disconnection fault. Extra current that flows during a phone call changes characteristics of a corroded joint.
You can double-check your filtered faceplate by unscrewing the faceplate and using a standard plug-in filter into the test socket on the master socket behind the faceplate. ( sorry if I'm stating obvious )
If it still drops without the phone connected, I still suspect REIN.
If you use your Netgear to run routerstats, I'd advise running the latest firmware for it. ( 3.01.38UK ) DG834Gv1 Page
Latest firmware has newer ADSL modem driver that should partially fix line stability problem that occured with noiser lines. I think the 2-wire and home hub use different chipsets, so should be more stable.

Fantasmo,

I've only just found this thread and what you are experiencing sounds very similar to this case.

Take a look through the rest of the blog, you might find something there that helps. It raises the question of where you are located, and whether there might be a common cause. Even if you aren't in the same area, there may be similarities that point to a common cause - for instance military radios and radar.

Hi Ratonastick,
Checked the Routerstats log this morning to find a disconnection just after 12am. No phone calls coming in or out at that time.
I've tried 2 different faceplates this morning and plugging straight into test socket and if I call the house phone a number of times in quick succession (maybe so it's overloading the line or something) then I'm guarenteed a drop in ADSL connection. Disconnection will sometimes happen after just a single call. These tests were done with no house phone plugged into the mastersocket. No other sockets phyically wired anywhere else in house.
I cannot replicate the fault making outgoing calls. I had mentioned several times to the engineers that I had noticed when calling the house there was a crackle or click when if first begins to dial and I've now noticed a click / crackle after several seconds of dialing.
Their tests never picked anything up.
I'm going to stick to the 2Wire for the time being as it appears to be a lot more stable (will still drop when called).

Hi Generaldisquiet,
Thanks for the link. I'm in another part of the country, Wrexham - North Wales, and in a relatively built up area 30 minutes walk from the exchange. There doesn't appear to be a pattern of my disconnections outside of phone calls. I'll continue to report back to BT.

I'm now just glad that I have something to test when BT say that they have fixed the problem, I'll just keep calling the house and see what happens

OK - different part of the country and no obvious common cause.

It's the time range of your losses of sync that are particularly interesting. One of the things that has worked for me has been to put the router on a timer, set to switch-off at around 23:30 and then on again at around 03:30. This means I miss the main REIN event and the DSLAM at the exchange doesn't see the router having a coronary. The result is that my IP profile doesn't drop.

It may be worth your while giving it a try for a week or two.

I'll certainly give that a shot once I can get the disconnections from telephone calls resolved as I'm getting disconnections through the day too.
Thanks for the information.

Update - I've called BT to advise them of the pattern of disconnections tied to incoming phone calls. They have arranged for an engineer to visit again and specifically test for REIN interference.
I'm really hoping that something will be found and at least when the engineer comes I can show him the problem whilst he / she is here.

This is really weird, a dodgy joint should cause a disconnection with a call in either direction. If the line is crackling during a call in either direction, ring BT on 151 and report it as a telephone fault, don't mention broadband. If there isn't constant crackling, you could try the BT line test on 151 or the link below from a computer NOT connected to your line.( ie someone else's broadband )
BT Line Test
If the test comes back as fine, I suspect a fault at the exchange, probably something like a faulty line card that seperates the voice and broadband signals.
It's a case of getting your ISP to contact BT again to check the exchange end of your line.

Maybe it's the ringing voltage - that only applies one way.

Sorry, didn't read your latest post correctly. Serves me right for trying to look at too many forums at once.

I'm ready to give up.
I am unable to replicate the dropping connection with my Netgear and Homehub routers. I can 100% replicate with 2Wire.
My only glimmer of hope if that there is an audible muffle whilst ringing but really disheartened that I can't get the others to disconnect.
Not sure what this means now.

Maybe your ADSL faceplate is faulty. If it has no extensions wired to it, you could take it off and just use a microfilter in the test socket...
