DLM Reset?

daley15 — Thu, 10 Nov 2022 15:21:55 GMT

I have recently moved into a new house and the VDSL speeds were nowhere near as good as they should be, I was getting 8mbps down and 1mbps up.

I have found the back of the faceplate was tapped to two futher phone extensions. I have removed these and now I am just connected to the incoming copper.

My upload speed has gone from 1mbps to 8mbps, but my download speed has only gone from 8mb to 10mbps.

Given the line has been in a poor state for years, will I need a DLM reset to get the speeds back to where they should be?

Cheers

DLM is an automated process. If your line is stable without any drop outs it will automatically set the best speed that your line can deliver.

What speeds were you expecting and what have you based that on?

Ahh okay, how long should it take?

DSLChecker reckons 35-40mbps, however both next door neighbours say 80mbps so I'm guessing the 35-40mbps is based on the old line condition?

please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information .

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal does not work if you have digital voice

enter your phone number and post results remember to delete number https://www.broadbandchecker.btwholesale.com/#/ADSL

Someone may then be able to offer help/assistance/suggestions to your problem

Assuming there is no fault on your line and the line is stable it can take but not necessarily will take a few weeks to achieve the best stable speed.

Unfortunately you cannot base your speeds on what a neighbour achieves as each line is individual.

If your speeds do not improve in a couple of weeks post back to see if anything can be done to assist you.

The stats don't look right with10mb down and 8mb up

Have you tried quiet line test?

Have you tried connecting to test socket with a filter to see if that makes any difference?

Dslchecker results?

Hiya, DSL checker results

Looks to me like the line has been heavily profiled

not sure what you mean by 'line heavily profiled' looks more like a line fault

what about quiet line test?

did you try using test socket with filter to see if speeds improve?

Quiet line test is fine, I'm wondering if the DLM has limited the speed as it the line had secondary sockets connected before.

Now they've been removed the upstream has incressed 8x where as the download has barely changed, so thinking it's the DLM still holding it back

if quiet line test ok then try using test socket with filter.

If the DLM was restricting your connection speed it would not affect the attainable speed but your attainable speed is only 10mb as well suggesting there is a connection problem

I am at this stage thinking DLM has limited the line due to the poor quality before I fixed the line, hence the upload has increased substantially however the download speed is being throttled by DLM?

BT do not throttle connections did you try the test socket with filter to see if that help by eliminating your master faceplate and your internal wiring

Re: DLM Reset?

daley15 — Wed, 16 Nov 2022 18:10:20 GMT

Yes, same speed with the faceplate off too

Then you need to phone CS 150 or 0800800150 from mobile and get another engineer visit as your connection speed is well below your expected speed

Hi @daley15, thanks for getting in touch.

Our tests located a fault (internal Bridge Tap) on the broadband service. You've arranged for the current active account to be closed and the services will transfer over to you on the 23rd of this month.

If the fault persists after the transfer has completed come back to us and we'll be happy to help you.

Cheers

John
