DLM Reset

MinniMan — Mon, 25 Jul 2022 16:47:25 GMT

Can someone reset the DLM on my line and turn off interleaving? My speed has been stuck on 67 mbps for a while and my ping has increased to 30ms.

I've had a look and I can see the latest profile for your line is "Downstream: 0.128M-80M with no error protection. Upstream: 0.128M-20M with no error protection" so there's no banding or artificial restriction on your speed.

Is your router plugged into your master telephone socket? If you haven't already, can you try the test socket explained Here? That'll rule out any issues with the internal phone wiring of your property.

I have 5C MK4 master socket and I don't have microfilter for the test socket.

Ah okay, do you still have the box for the router we've sent you? We'd have included a microfilter with it.

I don't have the box anymore.

OK no problem. What type of master socket do you have? Is it an Openreach 5C?

Re: DLM Reset

MinniMan — Thu, 28 Jul 2022 14:53:43 GMT

Yes, 5C. It's the one that looks like the attached image.

Cool. Yeah that's the latest. As your speed's below the estimates of your line, I think it's worth arranging an Openreach engineer to take a closer look. When could you be available for a visit? The engineers are available weekday timeslots (and occasionally Saturday's) of 8am to 1pm or 1pm to 6pm.

I live on the top floor in a block of flats and both my lifts have broken down so I don't want to put the engineer at a inconvenience. Are you sure you can't just reset the DLM on my line or on my profile?

@MinniMan As @Gandalf has finished for the day, I'll answer for him: With the details posted in message #3, there is nothing on PN's side they can adjust remotely.

I've done a DLM reset for you which should go through within 24 hours, but I'm not confident that it'll help.

If it doesn't help then we'd likely need to inconvenience an engineer.

The reset happen, my speed and ping are back to normal. Thank you

Awesome and the engineer will be happy that they don't have to climb all those stairs.

Let me know if there's anything else you'd need help with.
