Could I request a SNR reset please.
These are the current stats from the router. IP profile is set to 5 mbps
ADSL Link Downstream Upstream
Connection Speed 5888 Kbps 448 Kbps
Line Attenuation 39.4 dB 20.0 dB
Noise Margin 13.9 dB 27.0 dB
Last year after having a SNR reset I got the following stats with a IP profile set at 6.5 mbps.
ADSL Link Downstream Upstream
Connection Speed 8128 kbps 448 kbps
Line Attenuation 39 db 10.5 db
Noise Margin 3 db 24 db

If not, then seeing the variation of your SNRM during the whole of the day / night might assist in identifying sources of interference. RouterStats is useful for this as it will monitor and plot your SNRM 24x7. Any significant variation of SNRM will help profile the problem.
If there is still intermittent noise around, a SNRM will not help you. Though at the initial reset you might get more speed, as soon as the noise occurs, you'll get a lower speed resynch at the target SNRM. When the noise vanishes, you'll see the SNRM drift up again.
@Chris, given the way you phrased the question, would I be correct in guessing that the target SNRM on the line is 12dB? If yes this would suggest sustained issues on the circuit. Is there merit in

I didn't want to complete an SNR Reset for the SNR to then jump straight back up to 15db. The SNRt is targeted at 15db so something has forced it that way up.
I'll await a response from OP in the first instance though. I've attached some graphs for you to take a look at should you want to.

Are these graphs a new tool? I've only seen them on threads I'm commenting on...
If these are going to be used generally, it would be useful to have access to an explanation guide please. I am able to make a reasonable guess at what much of it means, but by no means all of it. I guess that there is significance in the colouring, but I'm not sure that all which is not green is of concern!
If this is a new PN tool, is there any possibility of / merit in adding TARGET SNRM as this would indicate DLM activity, as opposed to actual SNRM which just shows variability, possibly only due to MW interference.
Cheers,
Kevin
PS: yup some people do not realise just how dedicated many at PN towers are towards helping customers - numerous staff spend break / lunch / own time in the forums giving help and advice. Who said PN does not care about their customers?

The last reset of the router was because I had to turn off the mains for some electrical work to be done. Is there anything else which could be causing interference ?

Need to get this sorted, Netflix has been freezing often recently and is especially bad today which could be related to this.

Can you please post a full set of router stas, to include synch rate, SNRM, attenuation and error counts.
Still need to understand why the SNRM si so high - most likey cause is line nose. Have you done a quiet line test - dial 17079 select option 2.

Are those all the stats you need ? couldn't see any others. Sorry they are not that clear, if I try and align them better it just gets worse when I preview the message.

Quote from: hedkandi That number said it is not recognized.
Sorry typo, should have been 17070 option 2.
Would be nice to see HEC / FEC / CRC errors, but I suspect your router does not show these in the web UI.
Unless Chris (DCT) can find a reason not to, I think from here a SNRM reset should be tried - it might deliver what you want, if not it confirms that there is an issue which needs investigation with BTOR.
