Can you please give me an update to this issue.
My ping times to bbc.co.uk are now around 29ms - last week they were 19ms.
My upload speed was 17Mb/s now 14MB/s
My Download was 56Mb/s now 44Mb/s
All this occurred last weekend on Sunday and has not improved since.
I had the previous speeds for nearly two years, when they dropped from 70Mb/s.
To lose so much in one reboot of the router seems rather excessive.
Thanks.
Mark

You can check at http://speedtest.btwholesale.com/ and run Further diagnostics to get a bit more of an idea, or stats from an unlocked modem.
I any case you probably won't be able to do much about it I am afraid. Good luck.

He reset the line and wow - 13ms to bbc.co.uk which is 3 times quicker than it was (although slower than when I first got broadband - but hey ;D) speed is up too, although for me ping is what really matters.
Very pleased and appreciate the response from PlusNet - just a shame you guys cant press the reset button - he did that sat in his van outside on the drive!
Great service,Thanks

The reason I believe I had problem’s is due to some external garden wiring (now fixed) and this has caused quite a number of trips of the “fusebox”, hence confusing the DLM, that’s my theory, and the BT guy thought that may be the case too.
I blame the gold fish!

"0.128M-80M Downstream, Interleaving Low - 0.128M-20M Upstream, Interleaving On"
Unfortunately there isn't much we can do but in theory as long as the line stays okay DLM may choose to take it off at some point in the future.

Apart from one reboot on the first day when it added interleave its not rebooted since (I've rebooted now to try to get the ping down).
I'll post my stats from the zyxel 8324 I have - which gives me the best connection, and which has been on since the BT engineer called, just in case some experts can spot anything.... Its shows Annex B but that's a bug with the Zyxel I believe

I can see from those stats that a 'Delay' of 8 has been applied. This cannot cause a jump from 29ms to 80ms.
The delay of 8 can however, explain the original jump from 19ms to 29ms. As you can gain/lose a couple of ms by using different gateways (I can see a difference of around 4-5ms depending on which gateway I'm on)
I can also see that there is a small bit of interference on your line (which is probably why the DLM has kicked on) on your D1 channel. Your line attenuation is 12dB where as your signal attention is 16dB, meaning there are external factors adding more attenuation. There would be nothing that could be done in this case, until (I assume) you went below the lower limit for expected performance on your line.
It's possible you could just be experiencing crosstalk from another subscriber who's gone live on your cabinet.

Now the upstream looks like its not interleaving but the downstream still is. The pings are better too -19ms.
I guess I'm just going to have to learn to be patient. Something I'm not very good at.
I've posted my stats again for the interested and I appreciate the advice.

Quote from: Dav0 Its shows Annex B but that's a bug with the Zyxel I believe
Annex B is correct for VDSL2
You're thinking of ADSL which is Annex A in the UK.
