New user - random disconnects

[nidave]

I have been with o2 for over a week now and we regularly get 2-3 disconnects a day.

i have the router plugged into the test socket.
i know o2 do some training but we have had no choice but to turn the pff then on again to get our connection back.
it will be fine for hours then same thing - no connection.

These are the router stats at a disconnection at 2pm:

I have noticed the noise margin changing over the course of the day.
After a reset the SN margin is set to 7.0 (down). I am wondering if I have a line fault. any suggestions before I speak to o2?

my stats are now:

Think I am going to get a disconnect in the next hour or so. That seems to be the trend.

i have experinced the same thing and it was a fault on the line. call 02 and let them know whats going on. im my case i had an engineer within 24 hours.

Definately speak to O2 - it could also be a faulty router.

[nidave]

Spoke to o2 - very nice and helpful guy - not patronising.
They say they cant see any disconnects however the noise margin is all over the place.
They have set the noise margin to 9 and I will give that a few days.
If they does not work they say they will ask BT to check.

I would have thought that if they can't see disconnects yet you haven't been able to get online that there's a router issue? In my mind - granted this could be false logic - this suggests that the router itself isn't disconnecting until you reboot it, at which point it comes back to life until next time?

Is it nice and cool? I had one overheating.

Do you have an alternative router that you could try?

[nidave]

I never got to the bottom of things... my connection is stable now at 8 Mbps, I cant be sure it was something line related, something O2 did or something a reinstall of windows on one of my PC's corrected. (I have an initial image I use with all my programs and settings so it takes 40 min to rebuild a computer)

Am happy now Thanks to the guy form O2 who was very friendly and everyone who replied.
