At my wits end......

[#1]

Hi penfold,
One of our agents has just chased the complex faults team for an update on this issue, he's had a chat with your wife and updated the ticket with the latest. It seems it's looking like a phone line fault.

[#2]

Yes, thanks Matt.  I have removed my current phone, at the request of the comms team, and replaced with the most bog standard phone I have, a very old phone, thats not even tone dialing.....  Rebooted router as soon as the phone was changed.  Current stats below.  Heres hoping anyway. Its a good idea, anyhow, someone has thought of looking at my phone logs, as I am on Home Phone, as comparing them to the disconnects.  Alot of them appear to tie up to the minute.  Its a thought anyhow. 
Rate:  7896 kbs  444 kbs
Max Rate: 7896 kbs 876 kbs
Noise Margin: 4.0 dB 21.1 dB
Attenuation: 45.5 dB 24.7 dB
Output Power: 20.4 dBm 12.3 dBm
Upstreams a bit low, but its probably due to a high margin, downstream is the highest I have seen it.  Syncs at 6db Down/21dB up, I presume the uploads been capped?
Errors are low as well, I have attached a screenshot of the errors page.
I live in hope

Current Error stats to date.
DO these look OK?

[#4]

Hi Penfold,
Those are looking a lot better than your previous stats. Please let us know if you have tested the service with a different handset yet as per ticket 32419956.

[#5]

Well I really thought things were getting solved, but no..... my wife has said the light has been flashing on and off all day, and also I have seen, that tonight no sync since 7ish, till now, and syncs are poor.   Obviously not the phone then, as I did try another, the most basic handset imaginable. Can we escalate as high as possible, as this is getting rediculous, and rather tedious now, and I am getting to the end of my patience, if one more BT engineer says there is nothing wrong, I will not be held responsible for my actions
One thing I have noticed, is that when all these issues occur, the noise margin drops like a stone, then I lose PPP connectivity, then sometimes sync, but sometimes not.  just now, margin dropped to 0.9, from 12, lost PPP, but not sync.  When PPP came back up, margin was 16.  Any ideas.

[#6]

Penfold,
Apologies for not reading the whole history of your saga, and then just popping up with silly "ideas" at the end. (i.e. forgive me if these have been covered elsewhere in this thread, as they almost certainly have been!)
If the broadband is getting disconnected with a pattern potentially matching phone calls made on the line... and you've now tried a replacement phone handset without help... have you also tried replacement filters (or replacement faceplate as the case may be) and also a replacement router too?
As I say, you might have already done all these things, but thought it better to check to be sure, rather than assume these had already been checked before.
Hope you get to the bottom of it soon.

Hi Mike
Dont apologise, I appreciate the comments.....
As you say, the replacement handset appeared to work for about a day.  BT have themselves replaced the filtered faceplate at their last list and also the wire coming into the house, as the engineer said he could sync fine from the little box at the window, but not at the master, no idea if an RF3 filter was placed or not.  Ran routerstats last night, for an hour or so, SNR varied beween 15 and 8dB, but acc dropped to 0, and I noted this was where the connection to the router failed, for some reason.  I am using a 2wire HGV2700.  I have also used a speedtouch 585V6, with the same issues.  both routers are not new, and I do wonder should I try a brand new one.  Before BT replaced the faceplate and wire, I did buy a Linksys WAG120N, and this did the same thing, but maybe this was another fault.  Would another new router maybe help?

Do BT need to replace the wire between the window ledge and the master socket then? Sounds like it might be the location of the fault. No?
I would ask Plusnet if they could send you a new router to test with. If it doesn't help, you could always send it back.
Failing that you can probably pick one up cheaply on eBay.... any ADSL2+ one would be fine.
Two bad routers would be very bad luck... but I've seen it before (think there was a case of that was in these forums a few weeks back). Basically, you should try everything just to rule it out as the culprit.
Good luck

In response to this, yes we can send a test router if that helps. I'm not sure if you are aware but an increase in SNR has just been carried out and you seem to have been online solidly for over 9 hours now. Have you received or made any phone calls during that time? Let me know as if disconnections are still coinciding with the phone being used then there may be a filtering issue at the exchange that can be looked into, please don't bank on this being the case though as we need to make sure any internal factors have been ruled out too.

[#10]

Penfold,
Just re-read you last few posts and not sure if I got it wrong. Which was the the wire that BT replaced? Was it the one from the Window to the Master socket? Or was it the one from the street to the window?
If it was the one to the Master socket, then that is ruled out already, if not, it sounds like it might be a good place for BT to work next.
I'd take the test router for a spin too, even just to rule it out as being the problem.... although from the sounds of it the problem might lay elsewhere. However, the more bits you've proved it  "isn't"... the less bits left to be the cause!

Mike.
in essence since december, the whole line has been replaced from Socket to the Pole, and the the wires from the window to the Socket again recently.
@Adam, yes lets send me out a router, then we can be ABSOLUTELY sure there is nothing in my house causing this.  I am aggreaved that an SNR increase has been done, as I know the line is stable at 9dB, until these issues happen.

[#12]

I've just caught today's post in the nick of time. A test router is now on its way out via first class post.

[#13]

Well, I am not sure whats happened, but things have been stable for 22hours now.....  Ive done nothing my end, except put back my orig phone.
Current Stats
Rate:          6306 kbs  875 kbs
Max Rate: 6306 kbs 876 kbs
Noise Margin: 11.7 dB 11.2 dB
Attenuation: 45.4 dB 24.7 dB
Output Power: 20.3 dBm 12.5 dBm
As you can see, my attn is back to a normal level for my line now. The only thing not connected to the router, is an RJ45 cable going to my Home Plug Master, but I cant see how that will affect line stability.....
The margins at sync time were as atached.  For some reason my router gives the time I look at the diagnostics, as the current uptime on this screen, current uptime is actually 22hours+

[#14]

Not daft at all.
Have you got an AM radio? If you tune it to around 600 - 700 region and wave it around near the cable and the homeplug device do you get a lot of noise?
ADSL is pretty much just radio waves sent down the phone line. Anything that gives off its own radio waves can disrupt the signal severely.
I would also try leaving the homeplug disconnected for a while to be sure (if you can). It is possible you just found the cause!

Cheers....  To be honest, although I hope this has solved it, I doubt it, as during earlier testing, I had disconnected the Home Plug, to plug in another router, so doubt that's a cause.  Don't have an AM radio unfortunately.  However, I do wonder if its mains related, maybe occ mains noise, or surges, does that sound silly.  Where the router is, its on a table, next to a lamp, and the phone. Everything is connected to a standard 4way extension.  This is connected to a socket that was converted from single to double, by one of those attachments you can buy.  one port is used for the Home-Plug, and one for the 4way extension.   I wonder if properly converting the socket to a double, and then using a mains protected extension may help.....  Maybe its a bad earth here as well.  
Adam is sending a new router anyway, to totally rule this out, but again I doubt its the cause.  I am looking now at either Mains related noise, or a line issue.
Anyone any other ideas.  I can provide a photo of the current setup if  you want.

EDIT... Just been informed that the supplier has closed the fault.  [Censored], we dont even know if its fixed yet.. GOD, what is it about BT, they really need to get a grip.
