Line speed based on theoretical speeds? or wait and see?

[#1]

Thanks for the info about router stats, I've run it for almost 24 hours...which is longer than my connection has managed.
It just dropped off at about 23:15 last night ...no gradual degrading, running exactly as in my last post until then, until the SNR dropped straight to 0 and the connection was gone.
it came back on at 10:45am, when it came back with a SNR of 7db. It stayed on for about 1 hour and then straight off again, So 12:15 until 16:15 it's been off and then straight back on at 7db, even slower than last time:

Do you have a captured image of the noise margin trace through the period when the connection drops? Could you attach one to your post - click Additional Options and Browse to locate the picture. (It gets uploaded when you post, doesn't show in Preview.)

[#3]

Do the drops ever coincide with the phone being used or the ringing of an incoming call?
When the line drops it would be worth immediately picking up the phone to check if you can hear anything on the line.

Hi mattstead,
As you're in the test socket and still getting those speeds I think we need to wait for the faults team to check it. DO you have another router you can try, or borrow one?

I'll hopefully be able to attach some routerstats pictures later.....Although as the connection dropped again last night just before midnight and was still off when I went to work this morning I might not be able to. (straight plummet from 7dm SNR to Zero again)
I'm not aware of the phone ringing and disrupting anything, if fact I got a couple of calls yesterday, both during the connection and some when there wasn't a connection.
I do have another router...The one I used for 3 years solid with my other provider, at a much higher speed (albeit still slow). I had to use this when I first switched to plusnet as my Thompson hadn't arrived. Has anyone got the settings to manually configure it? As when I first used it on plusnet, it maintained sync but kept losing PPP connection.
I also have a Version 1 BT Home hub, that I've never tried.

The full set of router settings (including those where the default is usually correct) can be found on this help page.

Well, it's been off most of the day too, but it's on with the results below:

not sure which routerstats pics to put up but here are some:

Both the RX and TX plots seem odd, values are either 7dB or nil when disconnected - and remarkably non-varying. However the values from the stats are TX (Up) 11.0dB and RX (Down) 4.5dB. The time when those were taken coincides with the end of the second plot. Normally the TX value won't vary throughout the day but RX will, at least over an extended period of time.
Something seems amiss somewhere?
Edit: further thoughts - has the Routerstats configuration been set up? Should be set for TG585 v6 & v7 (even though it is a v8).
The attached plot is from my TG585v8, recorded over 45 minutes. The values of RX Noise margin shown tie up with those shown on the web interface.

[#9]

yeah, something was amiss with routerstats.
this is it going off last night:
And eventually coming back on this afternoon:
Strangely enough Plusnet were going to ring me this morning with an update....never happened. I think I'll be trying the other router later as I was loathed to change the set up until they had done their thing.

Right, just switched to my old router that well known and well respected "ZYXEL" brand!! anyway, here are the results it's showing strainght away:

noise margin downstream: 5 db

attenuation downstream: 59 db

noise margin upstream: 10 db
output power downstream: 12 db

All instantly looking more promising (attenuation less, SNR at 5db, download sync spped higher than upload) etc etc.
unfortunately it's not a router I can run with routerstats.

[#11]

spoke too soon. the zyxel did hold on longer but still dropped out. And still no call from plusnet.

[#12]

HI mattstead,
I'll do a bit of digging for you and see what's going on.

One of the faults guys called your mobile and got no answer so rang your landline and left a message with a female explaining the latest. That was about 1.20pm Your ticket has also been updated so if you can take a look we can continue to progress it for you.

By my wife and I didn't have any missed calles on our mobiles, and we both have answer phones...neither of which got a message left. The female on the landline was my mother in law, who was simply told to get me to ring plusnet back.....which I had done anyway before she got to tell me. Anyway, you say that my ticket has been updated "so if I can take a look we can progress it"..... Err, what exactly do you want ME to be looking at, other than an intermitant flashing DSL light on my router? I'm confused...I thought the idea of flagging up a fault and progressing a ticket was so that Plusnet could progress it with BT, not that I could look into the problem further.
I'm now assuming that plusnet, or rather BT who must now be dealing(?) don't work over xmas? as no one has been in touch......a bit like the family abroad who I haven't been able to skype for the first time in years at xmas. 
I'll try ringing plusnet then..see what they say.

Hi mattstead,
Sorry about that. I was just passing on what I was told. I'm just having a word with one of the fault managers to get this looked at for you.
