Noticed my ping had increased tonight.

11ms -> 19ms

Had a peek at the modem to find I am now synched at 70 something instead of 40. Vaguely remember Sky saying I was getting upgraded several months ago and it would be cheaper. OK, cool.

Stats appear to be:

I hope this is temporary?

[adslmax]

Has it been DLM resetted by Sky?

[RealAleMadrid]

You have been upgraded to 80/20 FTTC, this change causes a DLM reset so G.INP is removed but should come back on in a couple of days. You should then get near full (80 Mbps) download sync speed.

Cheers chaps.

Some more stats since I plugged dslstats in, more as a reminder to myself I guess.

Looks like I get a few (8) upstream CRCs/ES per hour. My internal wiring perhaps?

I've also had the landline plugged in this week which is never normally attached so I guess that may have not helped. Detached since this monitoring started, though.

[adslmax]

DLM will turn on your G.INP within next few days. Usually after 2-3 days of remain stable. You should see full 80Meg no problem.

[michty_me]

Are you rebooting the modem yourself or is it DLM taking action?
Something isn't looking right there.

[Ronski]

How many times have you resynced/restarted the modem?

[tubaman]

Are you deliberately capping the speed or does it now sync like that without capping, as if so it's looking like it's banded and you really need to stop re-syncing as it's only making things worse.
I'd leave it alone (like don't touch it at all) for a few days and if nothing changes I'd ask for a DLM reset as you've "had problems with a faulty router"

[j0hn]

I'll chip in the same as others.

DLM will never ever make a positive change to the line from you performing a resync.
It treats resyncs as instability and will apply banding (capping the line) if you resync too often.

You've gone from a normal 71Mb sync, to what appears 60Mb capped, then 48Mb capped.

Is this a manual cap placed by you?
If not...oh dear. That's some of the harshest banding I've seen in a short period of time.

Banding sticks. DLM adds it easy but takes months to lower it in small steps or it just never removes at all.

If it's a manual cap, why? That won't speed up G.INP.

edit: looks like a manual cap. Just noticed the upstream.

Why is the upstream capped at 11Mb? DLM treats upstream/downstream as separate entities. Capping the upstream won't affect downstream G.INP either.

IMO you are more like to prevent G.INP being applied by messing with the line than just leading it alone.

For most people it will take 2 days for G.INP to be applied.
It took 11 weeks for my line, 7 weeks for Tiffy's line.

My advice is uncap the line and leave it alone.

[boost]

They were all manual caps. I suppose I have an irrational desire to see my latency return to normal, I've never cared about throughput.

Patience is not one of my virtues, I suppose.

[boost]

OK, back we go:

As an aside, what is the rationale in not starting from 'the best point' on a DLM reset?
8ms of delay is ridiculous. Openreach are better than this.

[Moderator edited to remove the postcode.]

[Ronski]

I guess it depends on what you consider to be the best point. 

My brothers line took many weeks, possibly even a couple of months before g.inp was applied, although I think this was before they applied interleaving as standard.
