relative capacity occupation. You're syncing at 40% of the theoretical maximum for your line.

Perhaps something is causing big problems with the downstream adsl2+ higher frequencies? Really you should be getting a throughput of about 10Mbps (or more) with your down attenuation of 37dB. Since things were fine when you were on adsl1 it does perhaps suggest a serious noise or crosstalk issue with the adsl2+ signal...I get a constant ~11250Kbps throughput from my 36dB down attenuation on a adsl2+ connection (down SN margin ~6dB.)

What does the DMT bit loading (bit allocation) graph look like?

This has been the frustrating thing all along. Not only that ADSL max was fine (full sync / IP profile and fast path) but that the first 10 days of my ADSL2+ connection "appeared" fine. As you say, sync was around 11Mbps.

Got a new modem/router coming Monday and I've ordered up a new ADSLnation faceplate. That then should eliminate my problems being from my own equipment. Also my move to Xilo/Uno a week on Monday then should also eliminate the kit at the exchange. Matter of seeing what it looks like then I suppose.

Never understood what I'm really looking at with those DMT graphs.

But here goes anyway:

Graph shows all nice until 1.1Mhz, at which point ADSL2+ takes over, and there are gaps suggesting interference, rather than a clean tail off

The 12 target margin which you appear to have will not be helping matters, i.e. a change to a 6dB target would get you back to the sort of speeds you did have.

As people keeping saying the DLM process never really finishes, and it seems some noise introduced instability, which made the DLM raise the target to make things steady

Thanks for that.

I'll just try and show some patience (first to admit that I'm not very good at that!) and see what happens come a week on Monday.

How long ago was the router resynced before that screenshot?

You got some sort of low-pass filter on the line?

I thought you had already tried dongle filters/splitters in the test socket with only a router connected, different rj45 leads and different routers also...

"How long ago was the router resynced before that screenshot?" ... about 1day 10 hours

"You got some sort of low-pass filter on the line? " ... router plugged into ADSLnation filtered faceplate

Indeed I have/did. I had tried a Billion 7800N but now have a TP-link router coming (as I want wireless N). The new faceplate coming is maybe overkill.

Best of luck with the TP-link wireless n router and the new faceplate

Sorry I should have enquired about your rj11 leads also before but you will be getting new leads with your TP-link router anyway.

Edit: don't chuck your 585v6 out because by all accounts they are better than the v7 that I'm using.
