I've just thought of something.
I have a wireless house alarm. This isn't plugged into a phone line and the main alarm unit is at the opposite side of the house.
Could this be blasting out a wireless signal and taking out my ADSL line? Is this possible?
I ask this because I came home from work, used a wireless key fob to turn off the alarm, made myself a drink and logged into my computer to find that the ADSL line had gone down 17 minutes before checking. The time is cutting it fine...

Yes, and if you were monitoring your ADSL SNR margin over time using Routerstats you could probably discover a pattern. Coupled with using a portable radio to hear the interference, you could determine where it's coming from.

But you said everything at home was fine.....

Hence my "I've just thought of something"...

I've set and disarmed the alarm to no effect on the ADSL connection. The alarm is set every time we leave the house and since my connection will remain for up to a couple of days I don't think this is the culprit.

What about "monitoring your ADSL SNR margin over time using Routerstats" and "using a portable radio to hear the interference"?

I used Routerstats for most of a day. That isn't over time I know, but did show 2 disconnections and no immediately obvious cause. I'm not prepared to leave my computer on for over a week.
I do not have access to a portable radio at the moment so cannot try that method although I will try and get my hands on one.

Well, a couple of days and nights should do it. You really want to see if it does it at regular intervals over a 24-48 hour period, if it's a gradual decline or an instantaneous loss, and if it's different between certain periods like during the day and during the night.

I thought you'd done all this stuff and were pretty much at the stage of having a line fault as the remaining option.

Even so, AAISP will be able to fix it or at least track it down. You just need to be able to extricate yourself from the BT contract by getting them to admit you're paying for something that doesn't work.

I will plug my netgear router back in and start Routerstats up and see what I get until Sat morning.
I will try and get a radio tonight and give that a shot.
I think I've pretty much done everything I thought of at my end and the alarm was something that just sprung to mind when I posted before. I've checked the alarm logs and the disconnection times do no match up but that isn't to say it isn't doing a broadcast or something now and again.
Thanks for your help so far. I need an engineer to basically say they cannot help any further before I can break my contract without payment. It's £150+ I can't afford.

Yes, I sympathise. At least you know what to ask the engineer when you see him

lol yep
Well, Routerstats is up and running with my old DG834G.
Again, thanks for your help.

Hi
Quote Your SNR is 24 which means its not good

that is quite normal for the up line . synch at Upstream 448 Kbps which is normal the high SNR margin just means there is plenty of elbow room
The downline is 14.8 which means he probably has a target SNR of 15 db.Caused by previous problems /disconnections .
