thn-ag2 LLU Slowdown and Poor Ping responses frustrated of Hampton

Just to log my problem and hopefully feed this back to Plus Net as there is simple  way I can do this once "question" has been closed.
I havent had a problem , and indeed the service has improved, since that terrible October I think it was when Plusnet's LLU service for some of us was intermittant slow and bursting around for about three months until it was traced to a faulty card in the gateway I think.
Anyway a similar experience occured out of the blue three weeks or more ago and has just been resolved by me going onto the thn-ag3 test gateway.
My ping responses dropped, my speed went down to a 150bps crawl and my rout showed thn-ag2.
At one point I couldn't even get the router to login which might have been a  red herring.
Nothing had changed literally on my network and after unplugging everything, leaving the router off for an hour here and there, changing the hardware to a newer router I was still frustrated.
Indeed I have had speeds up to and over 7M a huge improvement since I had been used to speeds of 1-1.5 - 2 at most until about 6 months ago.
So anyway - nothing had changed and I'd lost all reliability last week - the most frustrating thing was not having any response other than the usual 1st line have you tried.... which I had. MY 15 years as an IT and electronics engineer had prepared me for the frustration as a user at the end of deaf ears to my problem. I initiated the DSL fault checkser etc etc and was asked many irrelevant questions - can you get to a web page ...well yes....but....is you connection slow - well...no its 7Meg but... ...yes it's 150bps...but.....
My ping results to bbc were  great great - rubbish - timeout timeout - great great timeout - you know the ones. I forwarded these onto pusnet with tracert results etc and I even promised to take my router into work and try it on the backup adsl line but ran out of time - thought the tech supporting my question latched onto this and gave me all the settings for it again.
NOTHING HAD Changed on my network or my telepnone line - I just wanted some point to point diagnostic to say my end was ok! I'm only 1000ft from the green box after all.
Anyway I left a  neighbour connected to the network to see if anything got better while I went away for 2 weeks - nothing changed - and have just come back to find Plusnet have had a speed fault -.problem - I'm on thn-ag3 and it seems to be back to normal
This is just my experience I would like to feed back to plusnet.
I was effectively in a poor connection state for a week before I went on holiday and this after about 6 months with no problems. When nothing has changed and one has eliminated all the faults one can only expect it to be at the isp or local loop. Some easier segemented testing might help isolate the problems for us. I wonder of my problem will come back once I'm back on tng-ag2 again
I have included all the interaction and you can read my frustration in my responses.

In response to a question about the reposrted up and down speed reported by the ADSL router results below
WAN Port Statistics:
Link Status: Up
Upstream Speed: 640 kbps
Downstream Speed: 8158 kbps
Node-Link
No physical changes have been made to the router or wiring.
The speed has gone unusably slow again (see oct 2006)
Was it the rain?
this is the only thing I can think of

Still timeout on ping responses.
Speed test about 100k
please Currently swapped my dsl504 for a new
zyxel ADSL 2+ to see if it is that.
here is the model
System Name:
ZyNOS F/W Version: V3.40(ACI.6)| 04/27/2006
DSL FW VersionCheesyMT FwVer: 3.4.1.0_A_TC, HwVer: T14F7_0.0
Standard:ADSL2
still no luck. very slow.

FRIDAY MORNING
After leaving both of my modem/routers dsl504 (now my secondary) and my zyxel prestige600 disconnected.
The problem is the same . ping to bbc.co.uk works with good times then just stops.
Web browsing is the same.
STRANGE thing is, the dsl504 previously a great and reliable backup now says LCP No Response and doesn't even get as far as the zyxel does.
We are heavily reliant on this on a daily basis and I have to go away on Monday and my partner relying on this who has a great need to be connected. can you please help sort this out for us.
please call my mobile if necessary 07702 xxx xxxxxx
Thank
You

Here is a what I found on the web with a similar "LCP Disconnect PRoblem - the blog is between the ****'s
This fault occurred out of the blue on a previously 7M connection. Can you escalate this to BT to check the line as soon as possible for us? I am ging to check my DSL504 at work today - if it works then it must be a line fault here.
LCP - Diconnect blog below......
***********************************************************
Just trying to set up a new ADSL connection for a mate using a Dlink DSL300G+ modem.
All settings are correct - same ISP as me. The modem reports the following error "LCP No Response". I now know that LCP is the Link Configuration Protocol.
Anyone got any ideas? The ISPs tech line is not manned on a Sunday.
LCP no response generally means that the ADSL device couldn't
get any response back from the router in the exchange.
Does the ADSL device show any signs of carrier detect? If not,
it may well be that BT haven't got it right yet.
If you can see the DSLAM's signal ok, but still get no LCP response
then it suggests either the ADSL device is faulty or there's a
problem with the exchange.
.............................
Sounds like something's chewing the ADSL signal somewhere, probably from the ADSL router upstream given that it can get as far as connecting.
Best thing you can probably try is removing the front plate from the
master socket (which should disconnect all the extensions if it's
wired properly!), and plugging the ADSL modem in on it's own.
..................................
A guy called round from the telecom firm and sure enough it was
a problem at their end - something not configured correctly.

Please find my Zyxel Router log below with the disconnects.
Please help, this is a genuine problem
No changes to my lan have been made or the phone line.
You can tell when we have no problems as we don't log calls unless there is a genuine isse.
There is one now -= please escalate this.
Thank you in advance for your help.

Thanks for your contact, we have recieved your fault ticket however it appears that while testing you may have entered your password incorrectly as logs show you not currently online and disconnected. Please let us know when you have reconnected and we will look into the speed issue for you.

Srange because it was true there was a password incorrect but that was on Thursday ans we have been logged on Through Friday and Today Saturday. Ireceived your message about incorrect password today at about 14:22.
We are connected but there are still timeout problems pinging but speed is up to 6.5mb when there is connection

Did you manage to test the router at work as you suggested earlier ?
If you haven't already tried I would perform a full factory reset of your router and then reconfigure it using the following settings:
Virtual Circuit Identifier (VCI) - 38
Virtual Path Identifier (VPI) - 0
Encapsulation Mode - VC Multiplexed (VCMux)
Authentication Type -CHAP
Protocol - RFC 2364: PPP over ATM (PPPoA)
Modulation Type - G.DMT or Auto
After the reset you should check the router manufacturers website to ensure you are using the latest firmware version.
When testing ensure your equipment is set up as follows as this will eliminate any internal wiring or cabling as been the cause of the intermittent problems you are seeing :
Connect the modem/router directly to the master socket (no use of extension cables) and ensure all other non broadband devices are disconnected from the line (phones, fax machines, Sky TV, alarm systems). Also try swapping the one filter used at that stage.
