      The simple cure is to reboot your router when the noise margin drops, your speed will be lower but the line will be more stable. This is the reason Sky set a speed on the line, to prevent this happening. I would start by rebooting your router when the noise margin drops to about 4.0 db. Having a .4db noise margin is like trying to order a pint in a very noisy pub, the barman can't hear you so you don't get service. It is the same with broadband when there is so much noise on the line that you can't pick up the signal, this causes the line to drop or give so many errors that it becomes very slow..

      Maybe I should have said barperson, then you could have used your imagination.

      I use a standard D-Link microfilter when plugged in the test socket. The router resynced while I was at work so the snr is alot better now with XTE-2005 still plugged in.

      Keep an eye on it, the faceplate you are using is transistor based which can make is more susceptible to the issues you have seen. If they return consider the BT ADSL faceplate.

      Thanks for the reply.

      I can confirm that there is one line into the property and four from that into the apartments. The black incoming line goes into a dark grey rectangular box with GPO (yes, it's THAT old) on the front and the lines into the apartments come from that. The apartments were built 37 years ago and still has the original wiring.

      The filtered faceplate is exactly like that, bought from your company.

      As it happens, this morning the connection speed was 10.2Mb so I didn't have to reboot for a change. Short of buying somewhere nearer the exchange I guess I'll have to stick with what I have.

      Thanks to everybody for your suggestions.

      OK, that socket really shouldn't be used as a master, no technical reason other than line testing. You really should have an NTE5 and filtered faceplate (also adds SOME surge protection). It won't improve the connection mind unless you are running other extensions off the back.............
