DLM reset

[#1]

Having switched from BT to Plusnet a few months ago I was hoping that during my switch my line would be reset so that my new connection would return to the speeds I once used to receive, however no line reset was completed and unfortunately my line is still banded as per my previous BT connection.

The only difference is that my BT line was set at 73995 and my Plusnet line is now set at 73993, while I understand my download (69.5) is within the acceptable tolerance as the increase of devices used within my property quickly utilize this connection due to online gaming etc every MB is critical for all other users within our home, therefore can I please request a DLM reset in the hope my connection will improve.

Previously I was using a draytek 130 modem and an Asus RT-AC68U router whereas the router was faulty and potentially was the route cause of my banded line, however all equipment has now been replaced and DLM just wont adjust my line no matter how long I leave it connected, so I am please reaching out to a member of staff that hopefully will add my line to the DLM daily reset list.

I have in the meantime switched to a static IP in the hope this will also improve my line/connection. 

TIA

Hi @mszune

I've arranged for your line to be reset now which should go through within 3 working days and you should get a bit more speed on your line afterwards. Let us know if there are further issues.

Hi @Gandalf 

Many thanks for your prompt action to address my question and arrange the said line reset, if only other ISP's offered the same prompt and professional service without beating around the bush with multiple excuses.

I tip my hat to you sir cheers!!!!!

Hi @mszune 

Cheers for the feedback and kind words. No problem at all, happy to help in any way I can. 

I'd tip my hat but I'm not currently wearing one. Wait a minute. *Puts hat on and tips it* There we go.

@Gandalf No problem at all fella, credit where credit is due.

I had noticed my connection had altered yesterday evening and my line IP profile has changed to 77.43, I'm now averaging 73 to 73.5mb.

just one query was my line reset so that all the previous line errors had been zero'd or simply a profile change like when you first join a new ISP?

I only ask as my line might revert back to being banded if not reset correctly.

Cheers

Excellent, I'm glad to see it looks like your line has been reset already. I've just prodded up the 'connection profile' on your account to the highest it goes of 78mbps (as it should be around the IP profile). Try rebooting your router and retesting your speed again, you may see a little more afterwards.

It'd have been a reset of the caution counters that DLM uses to figure out when to apply banding. By doing this reset, the line will be on an open profile with no banding but if there are errors or disconnections, then this will trigger the caution counters to build up again and may ultimately re-apply the banding. 

A full DLM reset is basically this plus other parameters are reset such as the SNR, ReTX and interleaving.

@Gandalf Once again thanks for the speedily response to my additional question with a further tweeking of my line, I havent seen a profile change just yet, but once I do I will reset again and then let the line settle for a few weeks to see if banding re-appears.

Kudos @Gandalf 👏🙌

No problem at all @mszune 

The latest 'tweak' I've done you won't see a profile change as this isn't actually anything to do with your line.

It's a profile on your account that if set below the IP profile of the line can restrict your throughput/download speed.

I've increased it to the max it goes so once your router drops connection and reconnects, you should be getting the fastest. 

Cheers

@Gandalf looking good!! 🙌👍

[#10]

Aye, now that's a good connection to game on. Good luck with the gaming!

[#11]

@Gandalf My line has been a constant 74.5 down for the last two months, although I've noticed some bizarre behaviour with it yesterday, my BT wholesale max observed has reset to 80-20 and yet my line speed now averages about 71.

I have naturally conducted a line resync by switching off the router and modem with no improvement.

Having run a speedtest direct from my router it reports a 100% loss; I believe nothing has changed my end and so I'm wondering is there a fault on the line?

Hello @mszune

Thanks a lot for reaching out. Given the nature of the Openreach network, line speeds can fluctuate from time to time, it's really normal. I've run a test on your line this morning and can see that it's syncing at full capacity.

I’d also bear in mind that the IP profile is typically between 90 to 96 % of a sync speed and your throughput a little lower due to overheads of the connection as well as particular settings which DLM may have applied. 

[#14]

Thanks for the feedback it is very much appreciated, so as my line with you guys is set at 78 I wont see a great deal of difference while it is set at maximum with OR?

[#15]

@Anoush my main concern is the data loss I see in the router when I run the sppedtest, should I be concerned with this?
