That's very specific spikes that you're seeing. Is there anything electrical which is cycling on and off?

In the same room as the router is an apple time capsule and a printer also attached to the router. I guess the fridge goes on and off all the time, but that's quite a way away.

Here is an updated one http://img200.imageshack.us/i/dg834gnoise.jpg/ with a couple of even bigger dips!

I just wonder if my router is getting a bit past it, it's a good 5 years old now.

Have you got any hard-wired extension sockets? If so, have you removed the ring wire from each of them and the master?

I don't think so. Nothing really has changed in the house recently.

So you're running the router from the master socket? Is it an NTE5, the type where the bottom portion of the faceplate can be removed?

OK, can you check for the ring wire, then, it's on terminal 3 if you have one, often coloured orange/white. It needs to be disconnected at all sockets (just lift the wire out of the IDC connector with a small pair of pliers or a hook).

Don't be tempted to set the phone line on fire. ;D

Enjoy the bbq - just had one myself. :)

Jeez that was one hell of a barbecue :red:

I do have the ring wire instead of disconnecting it, I am tempted to get an i-plate from ebay (http://cgi.ebay.co.uk/BT-I-Plate-Interstitial-Plate-iPlate-Faceplate_W0QQitemZ220437248961QQcmdZViewItemQQptZUK_Computing_Networking_SM?hash=item3353157bc1&_trksid=p3286.c0.m14&_trkparms=65%3A15%7C66%3A2%7C39%3A1%7C240%3A1308%7C301%3A1%7C293%3A1%7C294%3A50)

If I didn't go for the i-plate as my router is connected to an extension would I just need to remove the ring wire from the master socket or from the master socket and all the extensions?

Thanks

Glyn

Edited a few mins later - whoooah - ring wire disconnected form master socket - connection up to 6560 instantaneously from 5300! It's never been above 5400 before. Noise margin still at 6 db

You should remove the ring wire from all sockets. You may well get better sync still! If you get an iPlate, you don't need to remove the ring wire. If you're connecting your router at the master socket anyway, you'll be better off with a filtered faceplate.

Just goes to show why we recommend disconnecting it!!!

Just to update, I fitted an iplate, and sync now at 6880, and profile now at 6000. Speedtest results 5.86 Mbps, so an increase in speed of just over 33%.
Pretty good I would say.

The noise margin now varies between 1 and 3 where it was 6, I hope this is ok :o

Normally the default noise margin is 6. If yours is lower it is probably due to it being the evening when noise is at it's worse. Hopefully your line will hold sync and then in the morning you'll find that the noise margin is higher again.

That's okay if it's not causing problems, but higher is better. It's possible that it's dropped because you sync'd during the day (a quiet time in terms of line noise), meaning you achieve a higher than usual sync, and now at night (a noisy time) the noise margin has dropped a bit.
