I was upgraded to ADSLMax recently.
During the 10 day testing period and up until yesterday I have been getting good speeds with no disconnections/drop outs. The IP Profile was sitting at 7150K and when checking on the BT speedtester I was getting about 5.5Mbps download each time.
Yesterday I started getting slow download speeds so did another speed test which showed that the download had dropped to about 1.9kbps. Must admit I did not check the IP Config at this time. This morning I did another test and the IP Config is sitting at 1500K with download speed of 1300Kbps. It is 19 days since the upgrade went active so it is well outwith the 10 day testing period so I am at a loss as to why this should have happened, especially as during the testing period and up until yesterday performance has been exceptional. As I said no disconnections and consistent speed of 5.5Mb. Below are my stats which all appear to be ok and have not changed significantly since the upgrade was first done. From these stats and what has happened something appears to be amiss.
Well those stats look great. The only reason it should have dropped the profile down is if there was some problem that caused it to resync at a much lower speed. If the sync speed stays high it should move the profile back up again after 3 days.

Just done another test as follows.
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 1500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8096 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1375 kbps
I am assuming a resync would be required if I turned off livebox or had a break in the internal wiring between livebox and master socket within my house. I was doing some work on my internal wiring yesterday and the livebox, although powered up, was disconnected from the main line.

Can you explain what you mean by this. Sorry but it seems confusing. You seem to say if sync stays high profile should go back up, but at present its at 1500K which is well down on the original 7150K. Are you saying that providing no fault has developed and it was a case of a resync that the line will return to its original IP Profile figure. If this is the case then surely everytime someone switches their router off they are going to suffer slow speeds for Three days until the system at BT decides to put the line back to its best performing speed. If this is the case then I can see this as a potential for a lot of faults being reported. I can understand a data recovery situation taking maybe 5 to 10 minutes. Three days seems a bit of a technological shortfall in the system. I am sure there is a good reason for it although I have never come across a data network that would take that long to recover. An explanation would be appreciated - Thanks.
It might be worth checking with Orange if they have unbudled your exchange (LLU). My connection was fantastic, until they decided to make this "FREE" improvement to my connection which promissed greater speeds... I was able to download at 4500kbs prior, now I'm lucky to get 1000kbs... Nothing this end has changed, the morning of the upgrade everything was fine from the afternoon onwards it's been next to useless....
I am going to complain to ISPA and request that Orange terminate my contract with immediate effect and at no cost to myself as they are obviously unable to provide the service.

Potentially could have been that which caused it, no real way to tell now though.

It's just down to how the BT system works. The length of time is in order to try and keep the connection stable. If there was instability with the speed varying a lot then this system would keep the speed at a lower point so there were less or no disconnections suffered.
Understand resyncing isn't the problem, it's resyncing at a lower level, even if it's for a short time.
The system has 2 speeds, the sync speed is the speed of the connection established to the exchange this can and does often change so running data through at this maximum speed would for a lot of people mean disconnections whenever it dropped.
The second speed is the data profile, this is the main one that trys to ensure stability by keeping the data speed below the sync level and at such a point that the minor daily variations in sync don't cause disconnections.
When there's a large drop in sync the system lowers the data profile to compensate, an update to the system now means "if" it next resync's at a normal speed the data profile is not kept low but goes back to it's previous level. However sync'ing low 2 times in a row would then lock the data profile low until the system shows stability once again at the higher original rate, this stability period is 3 days, a resync after which should allow the profile to move back up.
As mentioned in opening response my IP Profile dropped to 1500K following some work I was doing on my extension wiring. I put this down to the continual breaks in signal to router causing the exchange equipmet to retrain and establish a lower and more stable speed. Previous IP profile had been 7150K since install with download speeds of between 5.5M and 5.8M. Having read this and other forums it appears that if when re-establishing a stable connection at a lower sync speed the system will return the line to its previous sync speed providing the line is capable. On day 2 foillowing the resync to 1500K I ran another test and the line had increased its sync to 2000k and has remained as such since. My stats are as follows:
ADSL_NOISE_MARGIN=15.6
ADSL_ATTENUATION=13.0
ADSL_ATTAINABLE=10688
ADSL_DOWNSTREAM=8096
ADSL_UPSTREAM=448
ADSL_NOISE_MARGIN_UP=22.0
ADSL_ATTENUATION_UP=6.0
ADSL_ATTAINABLE_UP=1136
These readings are very much in line with what I was getting with IP Profile of 7150K and the attenuations and noise margins are such that I would expect to get this sync. The only change in the stats that I can see is that the ADSL TYPE has changed to Interleave where previously it was set for fast. I fully understand what interleaving is for and so can not understand why the system has not changed it back. It has been 4 days since the resync. The line has not returned to its optimum performance. Is this a case of a stuck line which needs resetting and if so how should I go about this.

Hi tvman
Im afraid you have got more chance of meeting the queen than Orange sorting that out for you they just dont have the knowledge and expertise to unless its written in front of them to, keep pestering them but saying that it will just cost you a fortune in phonecalls m8
Hope you get it sorted good luck

Well the latest in the saga. Refuse to phone so sent email fully explaining what had happened. Guess what. Yep, got the old standard email from Orange Tech Support (oops, sorry I just swore) saying check this, check that. Sent email back to them this morning and asked them to read my original email as they had either not read it or did not understand the technicalities. The latter I expect. Told them exactly what was required on their part. To report problem to BT and get profile/line reset and remove interleave. Speeds & IP Profile were still low last night. This morning after I sent the latest email to Orange I ran another speedtest. To my surprise my IP Profile is back up to 7000Kps (150Kbps short of what it was) with throughput of 5800Kbps. I don't think this is down to Orange but more a case of either the system recovering, unlikely as my problem happened 6 days ago and everyone seems to be quoting 3 days as the normally recovery time, or, the BT system finally recognised that my line had dropped by more than the 30% to flag a fault, checked and found there was no fault and reset the IP Profile. Problem is the line still has interleave active.
I am loath to phone Orange incase they cock things up although I am tempted to contact them and ask to ignore my last email in case they do something to cock up my line anyway.
