Download speed capped at 60Mbps - DLM reset required?

PeteB17 — Fri, 02 Aug 2024 14:46:42 GMT

It seems that after my upgrade to Digital Voice and the new SH2 about 4 weeks ago, my download speeds (I’m on Fibre2) are stuck at 60Mbps.

Do I need to be patient and wait a bit longer for the DLM to kick in, or is one of the BT moderators able to assist in performing a DLM profile reset on my line, please?

Please ignore the short uptime, this is due to the automated BT checker rebooting the SH2 yesterday.

The line has been stable over the last 8 years we had FTTC, although over the years, the download speed has dropped from 80Mbps to now 60Mbps (blaming the old router)…

Many thanks, Pete

60Mbps is fairly typical for FTTC. It's what I get and I've always thought it to be acceptable.
What speed did you use to get that makes you think your speed has now been capped?
I'm also puzzled by the Hub details you've shown - these apparently show a download speed of 20Mbps/60Mbps - are you routinely getting 60Mbps measured at the Hub using something like fast.com?

@chrisjp The hub stats clearly show the line is capped.

Is there anything else that can be done from my side to get the DLM moving?

Thanks.

your connection time is only 17hrs are you having connection problems with line dropping regularly or are you resetting in hope speed improves or maybe both? without a stable connection the DLM will not start to improve your connection automatically

As stated in my first post, it was the BT automated checker that rebooted my SH2. I’m fully aware that manually rebooting the router can cause the DLM to hold off.

FYI here is a graph of my downstream line stats over the last 2 weeks - all seems very stable:

One week later and there is still no improvement of my sync speed:

I spoke to one of the BT “Guides”, but they don’t seem to have a clue what DLM is and the guide even claimed that enabling the WiFi on the SH2 hub would improve my line speed…..

Does anybody have any ideas how to get BT to perform a DLM reset on my line, please?

The DLM reset has worked and my line has just resynced at just over 75Mbps:

Thanks @StuartH @imjolly for your assistance, much appreciated.
