Roberto, thanks for your reply.
My router shows this, and this matches what Coms are telling me:
System up time:12 day(s) 14:20:26
Yet my logs show this every day:
1 2014-02-22 16:09:23 PPP Warning ppp0 LCP down
2 2014-02-22 16:09:23 PPP Error ppp0 LCP down
3 2014-02-22 16:09:01 PPP Error ppp0
4 2014-02-22 16:09:01 PPP Error ppp0 User request

My router constantly shows this:
Upstream
Downstream
Current Rate (Kbps) 1016
8087
Max Rate (Kbps) 1028
9220
SNR Margin (dB) 5.9
6
Line Attenuation (dB) 27
52
Errors (Pkts) 0
0
Yet my speeds vary from not being able to open the speed test page, right up to 7Mbps downstream.
I asked Coms to increase SNR to 12dB, still had same issues, then to 15dB, and still had disconnections etc. SNR now varies by itself between 3dB and 6dB
I don't know what this means but it always gives a fail on ATM OAM segment Ping:
Test Internet surfing
Test xDSL Synchronization Pass
ATM OAM Segment Ping Fail
Router wired directly into test socket. Same issues with multiple routers, Router connected directly to PC via Ethernet. I have up to 9 wireless devices connected via Wi-Fi bridge around the house with DHCP switched off and fixed IP's, there doesn't appear to be any bandwidth leakage.
I had these exact same problems with previous broadband supplier both pre and post LLU, but when I moved to ADSL24 in around 2009 things improved and I'd only have connection issues once every 3 to 6 Months (on LLU), but they were fixed by adjusting settings i.e Interleaving SNR margin, or, BT engineer working on the line.
But all of the above disconnections and wild speed swings have only existed since migration to Coms.
tracert gives me: te5-3.telehouse-east2.core.enta.net
and: te4-4.telehouse-east.core.enta.net
When my connection is down my phone line crackles, when the connection is up the phone line is perfect.
I don't think Coms know what to do.... they're reluctant to get an Engineer out because they say the line tests ok.
Some disconnections last for 2 to 3 days at a time followed by a sudden re-connection at dial-up speeds for a day or 2, then disconnections again, then suddenly everything working perfectly again.
My feeling is its one of those green boxes in the street, possibly water ingress as I know a lorry reversed into one some years ago and almost flattened it.
If anyone has suggestions I'd be very grateful.
EDIT: One other thing I should mention, speed-test.net has recently started putting my location as Liverpool and tests via a server in Douglas (Isle of Mann) based on ping, yet I'm actually based in London but when using a London server my ping has dropped to circa.35ms whereas it used to be circa.11ms.
