Capped at 40000kbit Sync Rate

[DiscoDave1]

Hi all,

Previously I've noticed that my sync speed has been anywhere from say, 43448kbit - 449238kbit, with arbitrary values in between. I've logged on my modem and I've noticed that it's bang on 40000kbit.

From the checker page:

I called BT who simply stated that as I was getting over my minimum speed there was nothing they would do. It just seems very strange it would be exactly 40000kbit - like it's been manually capped.

Any ideas on what this could be?

Thanks,

David

Not until you show the full connection stats.

Here you go:

Your speed is not manually capped as there is no manual intervention as everything controlled by DLM

according to stats your attainable is 43mb and you have 40mb and well within your estimated speed range I cannot see BT doing anything unless you have a line problem like noisy line with connection dropping

Thanks for your reply.

Are you saying my sync rate of exactly 40000kbit is just coincidence?

See this help page from Plusnet.

40Mbs is one of the fixed speeds.

That's interesting. Looks like I've changed bands recently then.

So as a follow up question is it possible to request DLM to be taken off/reset from my line?

Nothing will be done while you are within estimated range.

"Estimated Range" is kind of rubbish anyway. When I called BT when my connection was especially poor (34mbit) I was told it was OK as I was guaranteed 35Mbit.

Yeah, I didn't get it either.

After explaining the simple maths I was told

"Oh, your true minimum is 90% of your stated minimum."

Great. I'll just watch my connection speed continue to trickle down.
