Slow Speed / DLM reset

Hi i noticed that my download speed has dropped alot, i have been looking at old speed tests and over the last year or 2 i have dropped from high 30's - low 40's Mbps to mid 20's at best

Could i get a DLM reset maybe to try get it back up to what was was getting?

 

Thanks

Re: Slow Speed / DLM reset

Welcome to the forums, @cgordon . A DLM reset may not resolve your perceived problems. Sight of your Help desk tab (with personal details removed), and the result of a BTW Performance Tester (Advanced Diagnostics) would possibly be a better place to start

My current line speed is below the minimum guaranteed speed and i have multipul saved speed tests from 2019 and 2020 of my download speed at 38 Mbps and even as high as 44 Mbps

Re: Slow Speed / DLM reset

As you say, your current line speed is below the guaranteed minimum, but we need to discover why. Sight of your Help Desk tab from the router would possibly give us some insight.

Re: Slow Speed / DLM reset

Which router do you use? We really need your router statistics - Noise margins &c.

Also sync speeds and attainable speeds

 

Sight of the result of entering your phone number in the BTW DS:L Checker  will also help - hide your phone number though.

Re: Slow Speed / DLM reset

Something is definitely a bit flaky there, but I can't work out what. Did you spot @Mustrum 's edit asking for details of the BT Broadband checker?

Re: Slow Speed / DLM reset

Thanks. Whilst a DLM reset will no doubt increase your speeds again, you really should chase PN to sort out the underlying problem which keeps reducing your speeds.

How is your phone line, any noise or crackles, dial 17070 option 2 - is it your number and is it quiet?

Fix

Hello @cgordon

Thanks a lot for reaching out. It appears that on 21/08/2021, the line cut out 52 times, there's no way of knowing introspectively why, but I can see that DLM did slow the line down, and capped your download speed to 30Mbps as a result of this.

Going forward, I've raised this issue with my colleague, who will be requesting a DLM reset with our suppliers, please allow around three working days for this to be completed.

Current profile - Downstream: 0.128M-30M with Retransmission (High). Upstream: 0.128M-20M with Retransmission (Low)

Re: Slow Speed / DLM reset

Funny but I'm seeing the same, my usual speed is about 32M down. 8.5M up, but over the last week the rate has dropped, using BroadBandSpeedChecker I Get

We had a power outage about 10 days ago, so the router has been rebooted . I suspect the speed drooff since then but I didn't check for a few days so can't confirm the two correlate
