Our remote office is suffering from slow and intermittent internet speeds.
I have contactd our ISP (Demon) and here is what they had to say.
I went down there yesterday and there was no noise on the line. Reset both the router and the switch and worked fine when I left. Today our VPN connection has gone down so will be paying a visit at lunchtime for another reset.
Do those figures mean anything to anyone? Time to call in BT?

The connection has not been capped by us. The connection is very intermittent, and started dropping on 01/12/12. I am running a line test at the moment, to see if I can see the cause.
The line test shows this circuit is dropping sync heavily. The SNR on the downstream has fluctuated and has remained quite high, about 15dB on average, which is quite high, and could indicate noise on the line. The SNR on the upstream has fluctuated between 1dB, which is really low, and 8dB, which is fairly average. So the line is either noisy, or there is a device on the line causing interference. I would recommend connecting a telephone in to the adsl line, and making a test call and see if the noise is audible. If that is fine, then remove the faceplate from the master socket, and connect just the router in to the test socket, so remove any other devices. See if it stabilizes. If not, then change the equipment.
