And to both of you, , the recent discussion has been about possible reasons the delta reporting sometimes fails on FTTC. In particular, the failure of the PN system to detect the resync, as it completes before the PPP session is dropped.

In particular, have a read of this post if you missed it earlier .

On further thought, there may be such a mechanism in the BT Wholesale DLMs as well when controlling ADSLx. Maybe this is the cause of the IP Profile/line rate imbalances you sometimes have to run a check to find, followed by a manual reset. It isn't inconceivable that some ADSLx modem/routers are occasioanally resync'ing too quickly for the Plusnet system. It may just need a tweak downwards of a couple of milliseconds in the PPP/DHCP settings, as per the Openreach quote earlier, to fix both problems.

Well, 24 hours later the IP profile has corrected itself to 63.69Mbps, so one point to Bob

Well, that's interesting/surprising; & is there definitely no evidence of a new PPP session reported by the router at the same time?

I think the second quote in this post is what has caused it.

The question now is will the PN line rate adjust to match. I have my doubts, but it is possible. Depending on precisely how the delta report operates.

I just checked the log and it's showing a new session started at 5.30 this morning. (It wasn't me, I was in bed!)

Meanwhile, Plusnet profile is still 69.8 so that hasn't been updated.

My experience is that the IP Profile doesn't correct itself unless a new PPP session is initiated.

Can I have half a point then?

So, it does appear that initiation of a new PPP session is the essential trigger for updating IP Profiles.

However, the new PPP session may be initiated manually, instantly updating IP Profiles or by the OR managed modem feeding daily info to DLM that deals with it "in due course".

As we are all using the same unlocked firmware version for the HG612, I can't see why my connection always seems to need manual intervention to update IP Profiles.
I shall look at that more closely the next time my connection resyncs (upward or downward), just to see if it does eventually update without manual intervention.

Still not updated, so either the delta report hasn't been produced or it hasn't been processed, well over 24 hours after the BT profile changed. When it last went up it took about 24 hours, this is a change down and it is taking longer. Better that way than the other!

You'd think a PN rep would be able to comment on the theory, seeing as the problem on ADSLx has existed for years and the techies haven't fixed it. I wonder if the techies have looked at the timing q of the BT profile change. Also it would be interesting to know whether the delta report is a pull or push, and whether it is blanket or selective based on known PPP reconnects.

From the failure of your PN line rate to drop the implication is that it is selective.

Unless the techies have checked these things out they could be highly relevant.

A week later, the Plusnet profile still hasn't changed to match the BT profile. As it's higher, I still don't care!
