If you're still getting disconnects then they need to find and rectify the fault. Otherwise a DLM reset will be pointless, as the line speed will drop again.

Leaving BT wouldn't make any difference, as you'd still be using the same copper line from the cabinet.

Unless of course you go to Virgin.

Well I'm happy - engineer has been, happened to be the husband of my wife's colleague in school. Spent well over an hour fault checking, changing master socket (now a plasticy looking 5c) and now noise all gone. DLM reset BUT line speed still low compared to max attainable:

Could this be just because g.inp isn't yet active? I have check with BT and my profile is correct in that I'm still as showing as on the up to 76Mbps service.

Yes, the attainable is much higher as you have traditional interleaving applied. It would be nearer 55-56mb with G.INP. Glad you got it sorted, with a DLM reset as the cherry on top.

Yes, that's great . Exactly as John says re interleaving. G.INP is never applied by default on a reset.

When mine was reset a few weeks ago, G.INP kicked in on the second or third day after - I forget which. Just don't mess ! It will re-sync automatically.

Good - was hoping it might just be g.inp not being on yet.

Yeah it was good that I sort of knew the engineer. He was in no hurry and was more than happy to do the reset even though it was down as a line job.

He also swapped me to a different pair as there were 5 or 6 spare in the box attached to my house.

I can sit back now and fingers crossed - no more resyncs!!

Hahaha - yep I'm leaving the router well alone. I've also instructed the wife that if she unplugs it to plug hoover in, there will be trouble

Just had resync by looks of it and g.inp is now enabled.

Speeds now 60310 / 16894 so speeds back where they were at the start of this saga!

Once snr drops again I should reach 67Mbps like before

Praise be !

Hahahaha yep. Just glad my wife works with the engineer wife because BT sent him for a line fault. He was more than happy to do a reset though

Glad it is sorted
