This is a service that was upgraded from ADSL to VDSL on 29 April this
year. Since the upgrade I've seen re-syncs overnight, generally during
the hours of darkness with a slight preference for times around dusk and
dawn. The unreliability was not present with ADSL.
The V2763 router always reports "PPP Closed : Remote Terminating (PPPoA)".
Other routers have been tried but give poorer reliability. I've also
tried all the recommended things like swapping filters and faceplates,
connecting directly into the master socket, and different cables from
filter to router.
Sometimes the connection stays up for several (the maximum has been 8)
days; sometimes it fails 3 or 4 times per night. Daytime failures are
rare - once per month perhaps. So I think that a security light or
street light is causing interference. This is a rural area where
animals such as muntjac deer roam around at night and often trip
security lights.
I know it's not the security light at the user's premises because this
has been disabled for several weeks with no improvement. So I suspect
something further away.
I can of course report this to the ISP who can then call out Openreach,
so: ....
Has anybody here any experience of whether Openreach can do anything to
their equipment to eliminate this sort problem?
I've just reread the entire thread, and it doesn't seems to be making
enough progress, so I'll try throwing in some thoughts to see if any of
them spark anything in yourself or other contributors ...
1) Your suggestion of a security light is interesting, but I'm not sure
how one would supposedly affect the line, except perhaps by mains
interference from a bad PSU, but the PSU would be on all the time. I
suppose the switching on and off of the light combined with a bad PSU
might cause local mains spikes, but it's not something that I've ever
knowingly encountered, and why would that affect the VDSL line, unless
it affects the terminating equipment at either end? Many security
lights use WiFi, but again that's not something that should affect a
VDSL line, unless perhaps there's a bad connection along it forming some
sort of circuit? [I once had a Sony tape-recorder that picked up Radio
Bulgaria, and included it for free in my recordings - bloody
maddening!] You say it's a rural location, how far away is the green
cabinet from the premises? Would it be possible to mount a camera at
the premises pointing towards it, or at least along the path of the
line, to see if anything is captured, even distantly, such as a security
light coming on? Alternatively, you can buy trail-cams comparatively
cheaply that you might be able to hide near to where you think there's a
problem. My late nephew and his wife did this to gather evidence
against fly-tippers.
2) The night and day difference could be down to something affected by
temperature, rather than actual daylight, perhaps again a bad connection
in a line?
3) In my current home, a switchover between a normal rate and cheap rate
is done remotely by the system, I'm not sure exactly how, but often
these switchovers are not clean, and there are spikes. There are more
of these switchovers during the night than the day, especially in summer
when the heating is off, so there is no load if it's a 'dirty' one.
Kind of fits your pattern, but perhaps not closely, because these would
be events at regular times during the night - note that I'm not saying
these would be regular events, because sometimes the switchovers seem to
be cleaner, sometimes not, rather I'm saying that, if an event were to
occur, it would always be at the particular times that these switchovers
occur. I've not logged these closely, but I know of switchovers around
the following times ...
22:30 - 23:15 Hot water comes on
02:30 - ????? Storage heating comes on
05:30?- 08:30 Hot water
... and there are others for boosting the heating and maybe the
hot-water during the day, but they're more difficult to hear when other
things are going on.
The above is not much, but it's all I can think of right now. Hope it
helps anyway.
