Hi @stathe, thanks for getting in touch. I've had a check into your connection to see whether the current signal strength is causing any issues and although errors look to certainly be more commonly occurring you are getting around 0.8Mbps more than you usually would on 6dB which may outweigh any issues caused by the errors you're seeing.

General Information
NTE Status:		NTE Power Status:	PowerOn	Bypass Status:

	Upstream DSL Link Information	Downstream DSL Link Information
Loop Loss:	44.8	70.0
SNR Margin:	6.6	3.9
Errored Seconds:	2	2
HEC Errors:	0
Cell Count:	0	0
Speed:	798	2256

Maximum Stable Rate (KBPS):	1728	Fault Threshold Rate (KBPS):	1382
Mean Time Between Retrains (Seconds):	86400	Mean Time Between Errors Upstream (Seconds):	945
Indicative Line Quality:	A	Mean Time Between Errors Downstream (Seconds):	9

This is how your connection is looking when testing and as you can see it's only the download errors which looked to be higher than we'd expect to see on the lower signal strength. If this isn't causing too many problems your side then we're happy to leave the settings as is however if you do which for it to be bumped up then please do get back in touch.


Hi @westjensontexas, thanks for getting in touch and we'll happily adjust your signal strength to see how it goes for you. I unfortunately however couldn't locate your Plunset acocunt with your forum details however so if you could please private message me the username for your account then I'll get that sorted for you.

This is what I meant when I said  been there before  From a previous  problem Regards stathe

Thanks for getting back to us @stathe 

I can see the noise margin target is at 3dB as per the below profile: 

WBC 160K - 24M Medium delay (INP 1) 3dB Downstream, UC Low delay (INP 0) 6dB Upstream (ADSL2+)

The actual noise margin being higher than the target at 7.9dB currently may be indicative of an underlying issue. We can't adjust this itself, all we can do is set the target which is already at 3dB. 

Is there any noise on your phone line? From a handset try doing a quiet line test by dialing 17070

If the operational SNRM is found to be higher than the target SNRM then one of the following must be true

• The line is speed banded and when sync'd at the capped speed, the signal has a better than expected margin
• At the time of the last resync there was a lot of noise on the line (might have been the cause of the loss of sync?) and the router negotiated the fastest sync speed at the target SNRM and afterwards when the noise disappears the current SNRM will be seen to be somewhat higher than the target

The latter is indicative of presence of electrical noise, which might be audible (hence the advice to do a QLT) or it might not.  The latter is called REIN and generally can only be observed by close order monitoring of the router stats.  Which router do you have.

The line's not banded as per 160K - 24M in the above profile

Quite possibly and more likely. If there's no noise on the line, I can do an SNR reset to try to force the SNRM down to 6dB, then we can change the SNRM target to 3dB afterwards, but there does seem to be an underlying issue causing this.

Cannot edit my post above...

I remembered that you have a Netgear Router - these are very amenable to being monitored by Routerstats, which you can download from the link below.  The website has excellent guidance on how to use this.

This is not how it used to be  with such a high noise margin I cant understand why it has deteriorated so much

[#10]

I have router stats b on a graph   and can see this deterioration is comparatively  recent

[#11]

Un fortunately I will have to switch  it all off due to another problem I  hope this does not make it worse

[#12]

Any help appreciated  here  Thank you as this is hardly useable 

[#13]

Help can only be offered here if there is a clear view of what's going on.  Constant change (and that includes restarting to the router) alongside spot stats does not create a very clear picture.

If you have got router stats configured and logging, sight of all of the SNRM plots along with any plot showing a change in sync speed will be helpful.  If 7dB is what it takes to keep your line stable, then what is what it takes to keep the line stable ... in the presence of whatever it is in the environment which is causing problems.

The source of the problems could well be any power "brick" on any device in your home ... but until we can see SNRM plots, that is just speculation.  You are on a very long line, so any level of RFI could have a significant impact on the line's stability.

It switched off for a while and is now like it was as  sent a few minutes ago  I would like it to stay like that Thank you for your help

[#16]

It’s not a matter of wishing it to stay any particular way. If there is noise it will be variable. Have you made any progress with setting up router stats?
