IP Profile at a low 82% of the Connection Speed

DLM on my line has just completed its change to 3dB SNR margin with G.INP enabled, achieving a connection speed of 60192 kbps. Unfortunately the IP Profile seems stuck at 49.47 Mbps, ie 82% of the connection speed.

What is the best way to resolve this "stuck" IP Profile? My ISP has reset the DLM but initial tests are still showing the IP Profile at 49.47.

Any thoughts on this please, is it a waiting game or does something need to reset the IP Profile?

Is the ISP Plusnet I wonder ?

Yes, you must have seen my help request ?

Probably not. Plusnet are just bad for still having this issue that other providers stopped being a problem many years ago.

With Plusnet it's mainly an issue for customers who pay extra for a static IP. I would not be surprised to hear you pay for a static IP.

They need to reset your line profile/IP Profile. A DLM reset won't help. In fact a DLM reset would send you straight back to a 6dB SNRM target.

In my case I do not have a static IP but yes, I'm now straight back at a 6dB SNRM target following the DLM reset.

I have seen various comments that the IP Profile is not something that can be reset by the ISP or BT, which I find most odd when its clearly "capping" at a lower profile. I'm well confused at the moment on how this can get resolved even though its a recognised "profile mismatch" fault

This is an issue with Plusnet and I believe it has got worse in recent months. For reference I have a business VDSL connection with them with /29 of IPv4.

Years ago you could beat the IP profile into shape by dropping PPP, waiting ten minutes and reconnecting.

At some point things changed so that I would have to drop PPP, wait 10 minutes, reconnect and the IP profile would come right in the small hours of the next morning.

Now my best guess is you have to drop PPP, wait 30s, drop VDSL, wait some amount of time (30 minutes was enough), then re-establish link (I gave it a minute between VDSL sync and starting PPPoE) - and it will update overnight.

Having seen the OP's thread on the Plusnet Forum I don't think the Plusnet's Current Line Speed profile is to blame in this case.
The BT Wholesale IP profile is stuck at 49.47Mbps. When DLM reduced the SNRM target to 3dB resulting in a increase of around 4.5Mbps the IP profile did not change.

Plusnet do not seem to have realised that it is the IP profile that is stuck so have carried out a DLM reset which as you say will not help and the sync speed has dropped to 52.15Mbps with a 6.3db SNRM, the IP profile is still stuck, it should be around 47.45Mbps or even less because the line appears to be on G.Inp with retransmission high.

The problem is the BT Wholesale IP profile is not tracking the current sync speed.

Thank you for your suggestion. When DLM has "lost interest" following yesterdays reset, I will give this a try in a couple of weeks.

This was my original thought, but I've not seen any examples of how this is resolved. I'm wondering though if I changed to a static IP if this would bypass the current profile speed restriction? The other suggestion by ft247 to drop the connection for 30 minutes could be another one to try when DLM has put me back on 3dB SNRM in a couple of weeks.

A static IP will not help, the speed would still be capped by the BT Wholesale (or is it Openreach?) profile and by Plusnet's internal profile which is supposed to track the BT one and it sometimes doesn't!. This has been long standing problem and is possibly what ft247 has been suffering from on a static IP address.

You could try dropping the connection now to see if the IP profile changes as it is not correct for your sync speed, a single drop and re-connection should not upset DLM.

If you eventually have to get an Openreach engineer to visit I have a feeling they might be a bit baffled by this problem.
