Reading your other posts it seems to be with Xbox
Are you actually seeing any connection drops

thanks for the quick reply. My problems have improved tremendously in the last few days, though whether that's down to me replacing the Technicolor router with my old Netgear DG834PN, or Plusnet putting interleaving on my line, it's hard to say. I'm inclined to say the former as things started to improve almost as soon as I changed routers, but that could be just wishful thinking.
However, I still seem to get some annoying lag on Xbox Live, particularly in the evenings. Again, it's nowhere near the levels it was a few days ago but it's still enough to be noticeable (i.e. I'm a killing machine on Black Ops 2 during the day but largely cannon fodder in the evenings ;D). I also suffer with Skype video calls, although I will need to test that with another party just to be sure that it's not the person I'm calling who is contributing most to the video issues. I just wondered whether there are any tweaks i could do to improve things and Noise Margin was suggested to me as something to check
edit: didn't answer your questions properly. I get kicked off Xbox Live a few times but judging by the router stats it's still kept the connection overall, so not sure what that could be down to. I will say that I have open nat during the day but this seems to switch to moderate in the evenings. Have no idea why.

The first is that someone is piggybacking onto your router in the evenings - unlikely as you have tried two routers
Someone on your connection has P2P running
The errors on your connection are so bad it is killing your speed
I would suggest trying Routerstats http://vwlowen.co.uk/internet/files.htm with your Netgear then this page would be very informative - see picture

You have a fault somewhere if you are only getting that connection speed with a 12dB line. I used to get that with 48dB!
Edit: Unless you are on 20CN still...

How does your sync speed compare with the BT estimate?
Are you running everything wired or wireless?

my sync speed hovers around the 6.5Mbps mark, while the BT estimate was 7.15 I believe, so not too different.
My speed seems OK by and large; it's the quality which concerns me. As posted elsewhere I seem to have issues with Skype where I can't hold video successfully, and I suffer some lag on games (although admittedly not as bad as it was last week, and this seems to occur most in the evening for some reason).
The PC which runs the test (and Skype!) is wired direct to the router, while everything else, including Xbox, is wireless. I'm connected directly to the BT Master socket.
Oh, and in answer to your earlier post I should be on ADSL2+, since according to the Plusnet user tool my exchange supports it. How can I tell whether I have it?

Make sure you don't post anything with your phone number on it.
