DLM Reset required

Jamhawks — Tue, 04 Nov 2025 23:12:06 GMT

Hi, Please can someone request a DLM reset on my line?
I’ve replaced my master socket (NTE5C MK4) and fixed internal wiring — it’s been stable for over 5 days.

Current sync: 54,999 / 14,999 Kbps
Max attainable: 67,040 / 23,281 Kbps
SNR: 9.1 / 11.9 dB

The line looks banded at 55/15. Please reset DLM so it can re-train to full speed. Thanks!

Hi there @Jamhawks we have to run a test on the speed first and then we can request a DLM reset.

Is that something I need to do?

Staff will run the test during the day - they usually need you to be around in case you need to have the router plugged in directly at the test socket, or otherwise, @Jamhawks.

It's a good idea to complete your community profile first, for them to identify your account. Go via your avatar; settings. Add your Talktalk account number in Personal Information. SAVE CHANGES.

Staff are on here c 7am since the clocks went back and daytime only, Monday to Friday.

Great! @Jamhawks I will run checks on your line, do you have any active monitoring for life threatening health reasons which is solely dependant upon your TalkTalk Broadband or Telephone line?

For example a care alarm, lifeline, health pendant or fall detector.

No I dont have any of those.

@Jamhawks Will you (and anyone who lives with you) be able to contact emergency services while your services remain impacted?

Re: DLM Reset required

Jamhawks — Thu, 06 Nov 2025 11:08:16 GMT

Yes I have a mobile phone

Thank you for confirming, does the problem occur everywhere you try and use the WiFi, or just in certain parts of the house - for example upstairs, or outside the house?

Re: DLM Reset required

Jamhawks — Thu, 06 Nov 2025 11:15:46 GMT

Everywhere even when plugged directly into the router

Thank you, I am about to run a test that will look at the condition of your line. This test will identify any faults in the cables and associated equipment, between your home and the exchange, that could effect your service.

The result will allow us to determine if an engineer is required, or whether additional checks need to be completed with you.

A line test is currently underway. This checks the equipment used to provide the broadband service to your home - including the exchange, cabinet and line equipment.

This can take up to 5 minutes to complete. I'll let you know if this test finds a fault, otherwise I'll continue with further checks.

Please confirm the type of router you are using.

Re: DLM Reset required

Mandisa-TT — Thu, 06 Nov 2025 11:30:31 GMT

I'm now checking the current speed between the router and the Internet. This should take just under a minute and then I'll continue with further checks.

Re: DLM Reset required

Mandisa-TT — Thu, 06 Nov 2025 11:33:24 GMT

The average download speed tested from your router over the past 7 days has been 49.8 MB.

It has remained consistently above the minimum guaranteed speed of 40.02 MB, so there are no issues with the speed between the router and TalkTalk.

I'll need you to perform some checks. Can you tell me what type of device you are using when you experience problems?

If the problem you're experiencing is affecting more than one device, what's the main device you can use for testing with me now?

I dont think you quite understand what I'm asking. I’ve corrected internal wiring and installed an NTE5C master socket. My line has been stable for >6 days (157h uptime). Current: 54,999/14,999 Kbps; attainable ≈ 67/23 Kbps. Please raise an Openreach DLM reset/profile change ticket (provisioning). I need the Openreach reference number and expected completion window.

Thanks

I understand and I appreciate your proactive approach in correcting the wiring and installing the NTE5C master socket.

Before we proceed with raising a ticket for an Openreach DLM reset or profile change, we need to perform some initial checks to ensure everything is functioning optimally. This step is crucial to avoid potential issues that may arise from the reset.
