DLM reset if possible

[#1]

Could someone have a look at my connection which has been playing silly beggars all day today.

I managed to get connected at ~27000 but just checked again and it now dropped to @~21000

Was never this low and I guess that whatever may have caused the issue early tody (I had a warning from a piece of software that it had been inactive around 6 to 7am this morning) has set the DLM very low.

Thinks in advance

Sorry guys. This should have been posted to the Fibre forum not the ADSL one.

@dc8 It might be an idea to find out what caused the drop. I may be wrong, but I don't believe Plusnet can do DLM resets on FTTC connections anyway.

@jab1  On FTTC lines a DLM reset can be requested by Plusnet, it is actually carried out by Openreach but is only accepted and actioned if the line is banded at a fixed speed and the banding is capping the sync to that speed.

Thanks, @RealAleMadrid . You have reminded me of the 'rules' for such action, but I still think the reason for the reduction should be investigated.

Hi John,

The copper lines around here are prety bad so I would guess that the cold/damp weather we have had here the last few days could well be playing their part.

A BT engineer said that there were almost certainly micro cracks in the line and the fact that the line runs through trees in parts would also cause issues.

Normally, our fairly regular (at times) power cuts will also cause havoc!! although we haven't had any for a while (fingers crossed)

Not aware of anything that has changed on the router or laptop since I went to bed about 1am and discovering the issues when I had a look at my email and bits and bobs mid morning.

@dc8 The weather could be playing a part, but there may be other factors involved. I know some other regular posters on here will probably slate me for this, but sight of (1) the 'Advanced Diagnostics' from BTW Performance Tester  and (2) your Hubs Help Desk page - assuming you are using a PN Hub1 - would be useful. I won't be looking until tomorrow  morning, though.

Thanks for your post @dc8

I'm sorry to see you're having speed issues. 

I've tested your line today and the tests are showing there's banding on your line at 30mbps (full profile is "Downstream: 0.128M-30M with Retransmission (High). Upstream: 0.128M-20M with no error protection") but this isn't restricting your current sync speed, so I agree with the above comments that it'll need a little further investigation.

Would you be able to try plugging your router into the test socket as explained Here?  This should rule out an issue with internal wiring. Though based on what you've said we may need to arrange an Openreach engineer to take a closer look. 

Let us know how it goes.

Thanks for doing some testing and gtting back to me.

I will be able to do the master socket but not until after Xmas as I have to trail wires all over the show in order to connect to the socket!!

This is how things look from my router page at the current time

	Upstream	Downstream
Current Rate(kbps)	11514	25000
Max Rate(kbps)	11465	47258
SNR Margin(dB)	6.6	15.6
Line Attenuation(dB)	0	21.4
Errors(pkts)	20	0

@dc8  I have a feeling that @Gandalf has looked at an out of date profile from a GEA test which is useless to check the current profile. Your router stats show you are banded at 25Mbps so you need to push Plusnet again for a DLM reset.

[#12]

Potentially as our testing rarely shows a DLM profile produced on the same day. If we check this tomorrow I suspect we’ll see today’s profile. If that shows banding of 25mbps and the sync speed remains the same as it is now, we’ll be able to submit the reset. 

[#13]

I can see yesterday's data now. The sync speed's at 25000 and banding's at "Downstream: 0.128M-27.4M with Retransmission (High). Upstream: 0.128M-20M with no error protection"

I admit it's odd the sync speed's at an unusual round figure and it's not banded at that. 

I still believe it'll need a little further investigation. Let me know how it goes @dc8 

[#14]

Thanks for having a look at things again.

With Xmas and the New Year things are going to be FUBAR anyway with response times so I will just have to keep my fingers crossed and hope that the connection holds at a speed that allows the use of my TV/Sky boxes!!

I would be fairly confident that if an engineer was to visit they WOULD find a fault somewhere!! Everytime I have had these problems I get told that there is nothing wrong on the line and that I will be charged for an engneer visit and everytime the engineer visits they find an issue of one sort or another.

I would also be prepared to wager that when I am able to plug into the master socket, which was changed the last time I had a BT enginner visit BTW, there will be no issues. ALL internal wiring has been disconnected at the box as we do not use wired extensions and another engineer said it might cause problems so they were removed.

Anyway, enough waffle from me - have a great break and lwet's hope that something can be done to get me back to a respectable speed sooner rather than later.

[#15]

Thanks for getting back to me @dc8 

No problem, I’m happy to arrange an Openreach engineer visit either way though it may have to wait until next week.

We no longer charge for engineers to visit in any instances, apart from when you place an order with us but that wouldn’t apply here.

Fingers crossed your connection’s good enough over the weekend for you to watch stuff on your TV.

Have a good break too and Merry Christmas.
