Hi new +Net customer have been with Cable&Wireless LLU (virgin) for the last few years
I have always had a problem with my line in that the SNM drops drastically as it get dark at night and will drop the connection, routerstats jpg attached
However C&W dont use DLM as such so after a very low resync at night it was back to normal when i reconnect the next morning in daylight.
So im wondering what is the best way to manage this line now i have the **** BT IP profile to contend with.
thanks
Mike

If it is try connecting it to the TEST socket within it and see if you still get disconnections, by using the TEST socket you shouldn't get any problems from the house/internal wiring.
Have a read of this ....... it can help if you disconnect the bell wires (don't cut them) from all sockets not just the master.

bell wire had been disconnected for years, and i have a filtered faceplate, have tested with the router plugged into test socket and get exactly the same result come darkness.

The general consensus seems to be:-
Router on 24/7 is best.
If you have to switch off then just once a day for a long period is the next best thing.
If you can it is preferable to use the router interface to disconnect before switching off the router.

Since this occurs when you are connected to the test socket raising a dropping connection fault at http://faults.plus.net should be considered. It would be useful to add the RouterStats image to illustrate the problem.

I reckon the OP just has a line whose SNR margin drops a lot a night - such is life
I've seen two lines locally, one drops 1dB at nighttime, the other 3 dB at nighttime - approx same length of overhead pole run in both cases.
I do think that the op might be right if they have a long overhead multi-pole run this is causing the large drop in SNR - and overhead runs will be more suseptible to nightime interefence (caused by the raising of the heaviside layer in the atmosphere at night)
The disconnections are not faulty disconections from I'm reading in this thread, merely that the SNR has dropped to such an extent that the the router can no longer keep in sync and has to re-synch at a lower value, and each time the SNR drops further the router will reconnect at a lower sync rate. Then come daytime as the BT system is not rate adaptive, the router will not re-sync at the high rate that is now capable of.
My advise is indeed to switch off a night and switch on in the morning - I do anyway as a matter of course and always have done.
(Actually the routerstats trace shows a reasonably stable line in respect of the minute by minute variability of the SNR margin - on mine not only does the SNR margin drop at night but it also varys up/down quite significantly more than during the daytime).

In that case it would be best to switch the router off at night, preferably by using the disconnect tab in the GUI for a softer power down.

I'd suggest reporting it as a dropping connection - 9db variation is excessive!

thanks for all your replies
x47c
your reply was spot on, i have been turning off overnight now for the last week, and the sync has not dropped drastically, im still only half way through the first 10day period though
Jelv
it would be more then a 9db drop, if i were to leave router connected it would reconnect and drop again around 3am
so 18db total
Does anyone think that plusnet my take this on as a line fault when the training period is up ??

18db! With that massive variation in SNR? They should!
During the training period it establishes the acceptable speed range for your line. If later it falls below that rate you can report it as a speed fault, so it's in your interests to make sure you engineer things during the training period to make sure your IP Profile is as high as possible - and that will mean turning it off at night (if ever they do a SNR reset to restart the training you will need to do the same again). At the end of the training period check the BT speed test to see what the acceptable speed range is and you then need to run speed tests to prove that you are getting outside that range so leaving it on so it syncs very low should do the trick.

Give me a nudge when the 10 days is up and we can get it looked into.

If you saying that left alone it would drop 18dB overnight then yes I do think that is grossly excessive and a fault should be raised for it as the plusnet staff member has suggested.

One final question, i read somewhere ( long while ago cant find any reference to it now)
that there is a set percentage drop from a previous steady speed before BT/OR will consider this to be a fault.
true, false, typical Usenet misinfo
Much to my surprise turning the router off (via its control) at dusk and again overnight has not resulted in a plummeting IP profile....yet!
