snr just gone up

[lastofthetimelords]

Hi guys and Girls

been a broadband customer since the beginning of July, after 3 days my connection settled and has been performing great upstream snr between 5.5 and 6 db, giving me approx 3.5 mb download, uptime was approaching 5 weeks yesterday router lost sync and reconnected my downstream snr has gone right up its now 13.4 downstream, will the dslam sort it out or will i have to have the connection reset manually? any advice gratefully accepted, I am connected to master socket no extensions and using a new BT openrerach fitted filtered faceplate
regards

post all your stats ie speeds attenuation for up/downstream because if your snr has gone up then you should be getting more bb speeds if this has been reprofiled by dlm

as if by magic snr has returned to 6dB my connection speed was over 3.5 meg, not sure what happened there seems to be less than 2 meg
Broadband Link Downstream Upstream
Connection Speed 1958 kbps 798 kbps
Line Attenuation 58.0 dB 35.5 dB
Noise Margin 6.3 dB 11.11 dB
all seems not well now

if your snr is shifting about would indicate a fault on the line or localised interference post your stats from test socket with just router and recheck with a different filter

You might also download and run Routerstats Lite for a few days to show how your noise margin is behaving.
Internet Software

On the Graphs tab, set up the Sample Interval for every 60 Secs with 480 points per page. This will give you 8 hours per graph.

have installed Routerstats Lite as instructed, I do not have any filters I'm using a bt openreach fitted VDSL Interstitial faceplate, the only thing connected to it is my phone and my hub, I have done 17070 quiet line test, which reports back no echo and very little noise, all was well with the connection until Saturday afternoon snr was always around 6 down and 11 up, 3.5 meg down speed i did re-synch today @ 6db noise and 3.6 mb speed but it's since gone back to 13.6db noise and less than 2 mb downstream

Have you noticed, does the noise margin change much when using the phone?

[lastofthetimelords]

not a jot, line is uber quiet can't understand as to why the line could be stable for almost 5 weeks no drops, with snr of only 6db then all of a sudden mayhem

Unfortunately things do go wrong, the insulation on the wiring can break down, a joint can be disturbed by wind, water or even an engineer working in close proximity to it. Nothing lasts forever.

we hd engineers at a neighbours house last week, coincedence i'm not sure, router stats lite been running for a couple of days snr has returned to normal just over 24 hours ago and my speed is about where i expect it to be, i will keep monitoring
