New connection - slower than BT - G.INP not active

[#1]

I've recently switched from BT fibre to Plusnet fibre.  Currently I'm getting around 48Mb down and I had 56Mb down with BT.  I believe this could be down to G.INP not becoming active on my line yet.  It's been over a week now since the switch but G.INP isn't active, my H612 stats are given below.
My cabinet is enabled for G.INP and I'm sure I had it when I was with BT.  Does anybody know how long it'll take before it's active?
Thanks

According to the modem stats you posted your sync rate = 53717 Kbps As to why the sync speed would change  due to migrating  your FTTC service, the only reasons i know of are changing product ie, going from 40/10 to 80/20  ect, or the DLM stability profile used by the isp's  ,  I migrated no loss of sync  only PPPOE but once username /password updated  internet access was restored ,
Of course DLM may of removed G.inp, again unusual , have you tried powering off the modem for 30-45mins since migration to see if it restores things to what they were?

[#3]

Indeed - I am now syncing much less than I was with BT.  I had 56Mb actual measured throughput with BT, so the sync would have been higher still.
Same products, both are the 80/20 packages.
I'll try turning to modem off for 30 minutes at some point and see if that helps.

[#4]

No difference after powering the modem off for 30 minutes sadly.  No G.INP and ~53Mb sync.

Do you not know what the sync speed actually was with BT? Is it the same HG612 being used?

[#6]

I didn't check the sync speed just before I changed to plusnet and I can't remember what it was when I last did check (over a year ago), but speed tests would download at 56Mb.
Yep - same H612. 

[#7]

Perhaps tomorrow, one of Plusnet's CRT can post your profile and see whether G.INP is supposedly active.

[#8]

Your current profile is "0.128M-80M Downstream, Error Protection Off - 0.128M-20M Upstream, Error Protection Off" so G.INP isn't on your line.
I believe the transfer order will have reset DLM on your line so it may come back at some point but it isn't something we can guarantee.

[#9]

Thanks for looking at this Matthew.
Is there any other explanation as to why my sync speed is lower with plusnet than it was with BT?  Is there anything I can do about it?
I had put it down to G.INP not being applied to the line when I believe it should be and probably was with BT (cabinet is enabled, modem supports it), but I'm open to other ideas as to why my real-world download has gone from 56Mb to around 45-48Mb.
Thanks!

I am puzzled - comes with old age  - but why, since there would be no change at the cab for a move from BT Fibre to Plusnet Fibre and in fact no physical change at the exchange either, would the DLM be reset which I was led to understand could only be done by an engineer at the cab

[#11]

A number of us thought that about resets Jim, but that seems to only have applied in the early days. It's now done remotely.  There may have been some change in Policy at BTw/OR that DLM is now reset on migrations which it wouldn't appear to have been the case before.
I think it'll be a case of wait and see a while     (at a rough guess 10-15 days?).

[#12]

This is off-topic but if the DLM can be reset remotely, why are PlusNet unwilling to do so when customers ask for a reset? Their line here seems to have been that they can't do a reset (without an engineer visit, which costs), not that they won't or that it is inappropriate or that it wouldn't help with the problem presented.

[#13]

That is NOT the case. It's because BTw and Openreach won't allow it unless there has been a fault that has been attended and fixed. No ISP can do it on Fibre. This is not ADSL.

[#14]

BT use a separate network to us so whilst the physical side of things doesn't change there are other aspects which ends up resetting DLM.
It's worth pointing out that any DLM restrictions from a previous provider could still take affect.

[#15]

I'll give it 10-15 days then perhaps and see if the sync speed increases up to what it was previously?
