Upload speed saga

somniac — Tue, 03 Jun 2025 10:40:20 GMT

Recently had upload speed drop from around 4mps to almost zero. Download has been steady at around 18mps. Sent new modem to see if that is the problem. No difference. Engineer came today reset brand new modem using pinhole reset. Tells me the cache probably needed clearing even though use only for 48 hours. Showed me the read on his tablet of 8mps upload. A speed I have never had in 15 years. Me happy. He leaves. I do speed test. Upload still near zero. Any ideas? I have used ethernet connection on test. No difference. Have I been had?

do you get same result using ethernet connection and trying fast.com

what connection speeds do you see in the BT hub stats?

I will check stats on hub.

can you please go back to hub manager then advanced settings then technical log information and post the full stats from there. you up connection speed is very low hence why download speed is low

Download is OK at 20mps. I will post tech log info.

there is a problem with your connection as your attainable for both up/down is far higher than your actual connection speed. provided you have not moved to digital voice can you try dialling 17070 option 2 it should be silent with no crackle. have you tried using the test socket with a filter to see if that improves connection speeds?

Thanks for that. I have moved to digital voice. The d/l speeds I get are what BT promised me I would and what they quoted me in my contract (now run out) Not the upload though. Open reach are looking at the fault tomorrow (allegedly). Although the website is helpfully telling me that I have told them it is fixed, which I have not. Honestly.Their repairs system is **bleep**.

Here is the quote from the 2023 renewal. It has now expired. They have now reduced the minimum to 15mps.

There is/was a fault on the line and the DLM has capped your speeds to be more stable by the look of things.

Engineers used to be able to clear this, although most CP’s like to leave it and wait for the DLM to reset itself, usually after a couple of days.

(The old Cp trick was to just reset the DLM each time to resolve a slow speed issue without investigating what was causing it in the first place).

CP's have never been able to reset DLM on FTTC lines.

This is a few years old so who knows if it still operational, either way , no point really in resetting an unstable (faulty) line as it won’t be long before DLM intervenes again reduces the speed for stability as it did originally

FTTC reset of DLM in the beginning could only be requsted by an Openreach engineer after resolution of a fault.

Note: engineers couldn't do it by themselves they had to ring in and request it be done.

CP's have never been given the opportunity to reset DLM on FTTC connections themselves unlike ADSL. Thery can now request Openreach perform a reset but I would expect Openreach to remotely test the line first.

The big CP’s could as they were given the opportunity to do it about 8 years ago (same time they started sending their own “trained home engineers” out on faults), and Openreach engineers could do it with a call to 17070 platform, no need to call DCOE and request someone else do it for them.

Upload speed

Just realised I have already posted about this back in June. “Upload saga”Still not resolved.

. D/L is fine at 22mps. But upload has been under 1 for some time. Thought it might be a glitch and improve by itself but this has not happened. Had an engineer about 2 months ago who told me as D/L was pretty good, BT don’t really care about upload speeds. So suck it up basically. it’s not a big problem for me personally but it is lower than specified in contract. Any thoughts?

Re: Upload speed

imjolly — Sat, 25 Oct 2025 12:03:44 GMT

as was said in post in June you need to phone CS 03301234150 and request a DLM reset on your line which should clear it back to initial speed

Re: Upload speed

somniac — Mon, 27 Oct 2025 17:15:44 GMT

Thank you. I have tried this but I will give it another go.

@somniac

If you get no success when you phone then post back and we can ask mods if they can help find someone who can arrange a DLM reset
