DLM Reset

[#1]

My connection drops regularly overnight, probably once a week. I live in an area that is notorious for faults and poor cabling but have had multiple engineers saying there's nothing they can do.

They also enabled interleaving on their most recent visit but doesn't seemed to have helped, only makes the speeds drop further.

My sync speed on the router has now dropped to 13mbps. Would appreciate a DLM reset please.

Thanks

Do your ongoing line faults often cause your sync speed to drop, or is this a one off reduced speed problem ?

I'm just wondering whether along with a DLM reset, you ask Plusnet to change the "stability profile" of your line to a more stable setting ?.  Rather than repeat what I've written about this, look at this post where I describe the various settings.

Yeah I've noticed the speed will continually drop over a period of time.

Hey @selector14,

I am sorry to hear that the engineer could not help on your most recent visit I have ran some tests on the line while they did not show any faults affecting the Openreach line I have done the DLM reset which takes up to 30 to complete

Hi @Marsh,

Thanks for the DLM reset,

Would you recommend a change of stability profile to standard so it's less aggressive on speed?
Or would my speed still drop regardless?

Thanks

Hi @selector14,

We can certainly try it for nothing, Ill place the order for it and we can monitor.

If you get an intermittent connection or drops on your BB then we will probably need to move it back over to stable but we will just have to see.

The order will complete tomorrow, so I would give it around 5 days to see if the speeds change and if drops occur.

Please let us know!

Hi @LexLex2020,

Thanks very much.

I will keep an eye on it and update with any issues.

Thanks again.

Hi @Marsh @LexLex2020 

Just to keep you updated. Unfortunately I have had no change in speed and my sync speed is still capped to 13mbps.

Thanks

Hi @selector14 

It seems that your stability profile is still set to stable and hasn't been reverted to standard, would you like me to revert this stability order back to standard for you so we can test the speeds?

Hi @Windings 

With my current speeds the internet is noticeably slow.

I'd be happy to go with whatever you suggest would be best. If you think standard would help I'd be more than happy to try it.

Thanks

Hey @selector14,

I have placed the order to change it too 'Standard' this should complete within 1-2 working days.

Hi @Windings @Marsh 

Could you advise whether any change has been implemented yet as I have still had no change in speed.

Thanks

[#13]

Hi @selector14, Just had a quick check on your account for you and can confirm the modify to standard order has definitely completed. The only other thing i can do is trigger another DLM reset. Its a longshot but maybe the SNR margins didn't change in line with the modify order. 

Ultimately if the reset doesn't prove to be fruitful, I'm not sure what else we could do.

'@selector14   / @Windings - reboot Hub? might not work, but it is one thing I always try - any changes on anything that don't take sometimes need an unofficial 'kick'.😀

I think it's worth noting that changing the stability profile would just alter the parameters which DLM uses when making adjustments, so these type of changes aren't instant. I'd actually advise against rebooting the hub and keeping the connection as stable as possible to try to 'prove' to DLM that the connection can tolerate a higher speed. Even though another DLM reset will induce a drop, it may actually be beneficial as it will trigger a re-train and encourage it to make an adjustment quicker. 

Having said that, I've tested the line and I can see the sync speed has now increased to ~37mbps, although it's also flagged a number of errored seconds, which could affect throughput, so may need pursuing as a fault (this wasn't showing on a test done earlier today, so I suspect it's likely the higher sync speed has triggered the errors).
