Complaint about the outdated GEA test? It's clearly wrong and you can prove that.

Your stats show you are on Retransmission High for both Downstream/Upstream.

I know as the fault team only follow BT DLM system as the rules. They must follow BT data not the modem stats. They can't do anything about it, have to wait until DLM recover itself or in worse case might never happen for months.

Going to contact ASSIA over FTTC DLM complaint of quicker to reduced sync rate but take ages to recovers via this site https://www.assia-inc.com and asked them to make change to Openreach DLM adjustment such as recover DLM within 7 days of stable on FTTC not waiting for months or never happen until engineer reset at the cabinet is total out of question until the fault on the line is fixed.

The case was back in 2014 over BT DLM over RAMBO here: https://www.thinkbroadband.com/news/6726-assia-court-case-forces-openreach-to-turn-off-dlm

What?   
I'm well aware of the ASSIA case....  we've talked about it on here many times and in much greater depth than that article.

I have no idea what you think ASSIA are going to do - other than to be quite frank laugh at the thought of it annoying a BT Openreach customer.    Its all been battled out in court. 

Whilst as a result of that court case Openreach has changed their DLM and it does seem to take longer for banding to be removed*...   engineer resets are an Openreach decision.   They are trying to do something about that though and   it is currently a work in progress.

Max that really is a bad idea about ASSIA as I 100% guarantee it will get you absolutely nowhere and do nothing other than wind you up more.

[adslmax]

@Kitz there is a big chance for DLM Reset to removed banding on the line, is to downgrade to 40/10 then upgrade back to 80/20 but I think Plusnet are not allow to do this way? I can ask the fault team tomorrow see what they have to say.

[kitz]

There is no guarantee it will work.  We have seen product changes which dont.

As regards to whether Plusnet will do it.   It will cost them as they will have to pay for the downgrade.   Cant recall off the top of my head how much it is. 
There may also be a fee for them to re-upgrade, there was a special offer running for upgrades, but that may have now finished.   Too tired to go searching.

[Chrysalis]

max you really need to learn to accept what you have and just get on with life, because your addiction will go crazy with how long the recovery is expected to take.

[Ixel]

Indeed, it might work but there's no guarantee. Plusnet will most likely have to pay a regrade fee both for downgrading and upgrading your speed unless the special offer kitz mentioned is still running (I haven't checked either). This will obviously start a new contract term too. You have nearly full speed and G.INP (not the traditional and god awful interleaving/delay), I'd leave it at that and just wait for DLM. You may be able to encourage it to take positive action a little sooner by applying a hard cap but given you've only lost a small amount of speed and don't have an increased ping I wouldn't bother.

Retransmission High to Retransmission Low, on both Upstream/Downstream. Progress Max, progress.
Keep being patient DLM is doing its job.

Yep first time DLM made the change after 9 days waiting. So, hopefully shouldn't be too long for upstream interleaved to be turned OFF and restored downstream back to 79999K.

Does dropped PPP session affect DLM like soft disconnection to different gateway?

Only losing DSL sync, enough times, will upset DLM. PPP connections have no bearing on DLM. It's why I prefer to have the router and modem as two different devices, as DrayTek's for example have the unfortunate requirement of sometimes needing to do a restart on certain changes to the router configuration.

[adslmax]

My modem went down for couple of minutes for no reason. I thought it was DLM re-sync it but it didn't. Look like DLM will act now because of loss of power.


Hi adslmax

This is to let you know that a resync/restart occurred on your line at 19:20 on Wednesday 22nd November 2017 local time (+/- 1 minute).

Reason: 0 Loss of Service

Current Downstream Sync Rate is now 74000kbps @ 10.0db SNRM. Attainable is 89381kbps
Current Upstream Sync Rate is now 20000kbps @ 14.4db SNRM. Attainable is  33093kbps
as measured at the time of this email.

I am not at home at present but email just alert me.

[Jasonkruys]

I'd love that. For months I appear to have been banded or something at 35, and my upstream has taken quite a hit! Whilst there is not a huge amount of margin on my line, any little helps at this speed!

Upstream interleaved is now switched off by DLM. But still stuck at banding 74000K
