My connection dropped from 79999 down to around 38Mb the other week, No idea why but a reboot of the router got it back to 72mb and my speed followed suit and came up to around 68mb.
Last week another reboot got it back to 79999 but the speed has not changed. Still showing 68mb max. Would that be a stuck IP profile? Or something else?
It's no biggie. Only lost around 8Mb or so but still

Do you mean "Max attainable" or actual sync? (Your sig is confusing).
Post the full stats please. When you resync, is it always to exactly the same sync? A post with before resync and after would be best.

I dont see how my signature is confusing. Attainable rate is just that, and the connection rate is also, exaclty what it says. So I am confused to how you are confused! xD
Anyhow they are out of date stats. I will update it.

DSL up-time: If you mean it was 79650kbps before the reboot as well as after that suggests some sort of cap. The fact your Attainable has risen since the one in your sig, along with the D: 5 line, suggests that Openreach DLM has introduced G.INP on your line. Possibly with a banded downstream cap, rather than it being a TalkTalk cap,

I have had G.INP for a long time now.
As for my old stats in my sig, they were old, months old.
My line was steady at 79999 down and 19999 up with downstream snr of around 8 with an attainable rate of 98mb ish for quite a while, then one day I noticed the line was slow and upon checking the stats the downstream had dropped to 38ish and the snr was 6db and an attainable of around 83mb.
Thats when I did a reboot a few weeks back and got it back to 73ish and the stats have been as they are now since with the exception of another reboot to get it from 73mb back to 79650.
One thing of note is the Interleaved depth. It has always been low on the upstream but the download was always around 2500 but now its only 5!
At any rate rebooting or switching off the router for a bit has not got that last few mb of speed back.
Here is a screen grab from my samknows whitebox of the download speeds. Seems to hit a wall at 68Mb

Just realised a minor point - your sig also says TalkTalk 80Mbps. There is no IP Profile on TT so it can't be stuck.
Re G.INP, with an interleaving depth of 2500 G.INP may have been available on the cabinet, but it was not active. The drop to depth 5 is typical of what happens on BT Wholesale circuits where it drops from 4-figure numbers to 8, or occasionally 16. I assume TT are requesting different DLM configuration from BTW.
Why the whitebox is peaking at 68Mbps I have no idea. Are you wired or wireless to your router with your computer?
It looks a bit like cross-talk has caused errors, initially giving you high interleaving depth, and G.INP kicking in has lowered your sync. With the sync also being fixed, though I would expect the upstream to vary a bit, banding is almost certain. This seems to take weeks to months of stable connection to be removed.

While no IP Profile on TalkTalk do recall one other TalkTalk user having a similar issue on FTTC recently.

Makes sense. BUT I did defo have GINP enabled on the DS on my line a long time ago confirmed by stats from the unlocked OR modem I was using at the time. So dunno if it was disabled and later re-activiated or not.
I have been using a talktalk AIO router for a while, around a year maybe, 10 Months.
Speed tests also show the same.

I think I have seen it said that changing your modem removes G.INP. Which would tie in. Then there is a wait for it to be re-activated if needed.
With interleave depth 2500 it was definitely not active.

Yes, I do remember another recent poster with this strange D: 5 interleave depth, and commenting that I didn't understand it.

Maybe TalkTalk is quietly running something that behaves a but like the IP Profile but is not the IP Profile and this setting on individual lines can occasionally be wrong

Agreed, but how it can get the interleave depth to 5 is a mystery to me. Unless it is the default on one of the OR options.

Just got off the phone with TT support about this very issue.
I ordered a speed boost last night, this morning my router was synced at 26mbps down. Restarted the connection a couple of times, then rebooted the router. It now syncs at 79999 down, and 19999 up.
Speedtest shows 18mbps upload, but still only 38.5mbps down, exactly what I was already getting.
They went through their script, and decided that I need a new router. I doubt that's the issue, but we'll see.

|

So what is so odd about a depth of 5?

Only ever been seen on here on from two users as far as I know.
On BT Wholesale circuits, even though we are talking about the Openreach DLM, it is 1 - Fast path, 8 - minimal interleaving associated with G.INP, or in the high hundreds or even thousands for normal interleaving.

I was bored today and dug out the OR modem and connected that back up.
But I cant remember where the Interleaving stats are in this info:
Its also interesting to compare this info with what it was like when I first got VDSL2 (http://forums.thinkbroadband.com/fibre/f/4324380-fibre-installed-eci-modem.html?vc=1)

Try here for an explanation of what the parameters mean.
D is the interleaving depth, so it's 16 downstream and 8 upstream.
|
|
|
As jaydub says. But to my mind those are quite high figures for a line that has G.INP active. The Delay of 3ms on Bearer 1 looks odd to me as well, but I can't check my own at the moment.

They match the downstream on my line, where INP=48. Quite normal, I think, on Huawei cabinets, for the depth to be 8 or 16.
My bearer 1 has the same INP/delay settings, and the same framing parameters, downstream.
I don't have G.INP activated upstream, so can't compare.
|
|
|
I agree re the depth 16 down, but 8 up is surely unusual? And a downstream delay of 3ms on Bearer 1 alongside zero on Bearer 0?

It is unusual upstream, but only because any form of retransmission upstream is unusual. However, this line has it (with INP=47).
Bearer 1 always seems to be very heavily protected. Note that it uses a block size of 32, with a parity overhead of 16: half of the bandwidth is stolen for protection. I get the same INP, same delay, same block size, same parity.

Those results show more variance, but are all with the same router, and same 80/20 sync speed. In most cases, the change in behaviour does not coincide with either a resync or even a new PPP session.
