You could try downloading Routerstats and seeing if that can get to the data, Clive.

I have figures for you Rik.   All meaningless to me!

Not sure if Rik will be back in tonight, Clive, and he's away for the whole day tomorrow!

Those figures look healthy enough, Clive, you should be on a 5Mbps profile, for your attenuation and margin, that's about right. It looks like BT's dynamic line management software has increased your target noise margin from 6db to 9dm in an attempt to stabilise the line, but otherwise things look healthy.

I still believe the engineer. If you're getting frequent disconnections (which your previous profile implied) then either you have a problem on the line or with your internal wiring, and that's what we need to diagnose. Do you have the modern, NTE5 master socket, they type where the bottom part of the faceplate can be removed?

[Clive]

I have an ADSL box V 1.0 Rik.  When I remove the screws and pull the faceplate off, the BB becomes disconnected.  There is another plate behind and the lower part of that can be unscrewed but I have no idea what is behind that.

[Simon]

What I think Rik is looking for is a test socket, which may be behind the first plate you removed, Clive.  The idea is to connect the router direct to that socket, with an ADSL microfilter, to see if the connection speed improves.  This indicates whether the problem is within your internal wiring, or outside, as you are bypassing any internal wiring by connecting direct to the test socket.

[Clive]

The ADSL V1.0 box has an inbuilt filter and protects all extension sockets in the house.  When I remove the faceplate, there is no separate BB socket behind it.  I do have spare microfilters which could be used as you suggest but that may be putting 2 filters in the circuit. 

[Simon]

When you say there's no BB socket behind the faceplate, is there a telephone socket, to which you could attach a microfilter, and thus connect your router?  I'm not sure if filters can 'double up', as it were, but you may be better off hanging on for Rik to come back to us on this, as this box you have may be something completely different to what I'm thinking of, Clive.

[Clive]

Yes, there is a phone socket behind into which I could plug a filter.  I changed the BB cable today but that made no difference. 

[Simon]

I think that's what Rik will ask you to do, Clive, and then recheck your speed and router stats.

[Clive]

Ha!  They have done something at long last: (unless it's the new cable but that made no difference to begin with.) My guess is that this will be fine for 4 or 5 days and then drop back to 300K again.

[Simon]

I wonder if you have a bad connection somewhere?  Maybe that ADSL box is playing up?

[Clive]

Next time it goes I'll plug into the inside socket and see what happens. 

[Rik]

Your profile has improved, but your line stats are much worse, Clive - lower sync, higher noise margin. There's still a problem.

[Clive]

But where is the problem likely to be Rik?
