Looking at the facts as you say and what the op posted it most certainly does look like capping/shaping.

This post shows that he's getting the speed for his profile through BT..

I've just completed one Test on the BT site which gave a download of 4122 kbps.

On logging back to my ISP the speed on two alternative sites gave 1.95 mbps.
These I suspect are being limited by the setting of 2000 which my ISP manually entered yesterday.

Hopefully Plusnet must be able to make some progress with this now.

At one point they confirmed they suspected the problem was not with BT and all the evidence confirms this.

Next time maybe you should read the whole thread before making comments. I was actually keeping away from the fact that this is Plusnet with whom so much dirt has flown over the last year, but the facts speak for themselves on this one.

Pressumably... You've not logged into the Performance tester correctly. You need to put your phone no and username@isprealm

I have seen that said a few times now - but it's not what I have to do? I connect to http://speedtester.bt.com/ and it asks for my phone number. There is then a pause (reading the page I would guess it is doing a speed test between the tester and my ISP) and then it goes straight into the speed test/show results sequence.

At no stage do I have to enter a username

(stuck on a 500Kbps profile for a line syncing at over 6000Kbps for well over 3 days now)

mhmmm if you look at my last sentence

"I am also wondering about if delta reports have been received >> acted upon, and the overlap time inbetween this period.
Then remember it takes a reconnect to see the speed increases."

Something restricted him... he was stuck at 500.. what caused it to go down that low.
Then say, if he gets an increase-profile .. and it can take up to a day to kick in.

But what happened to the delta report that BT are supposed to send.. why didnt that get increased in the first place?

Then.. a bit later he physically logs off to perform a btw speed test.. upon reconnection he gets the higher profile of 2Mb.
Why did it take a login to another realm before the increase to 2Mb kicked in?

Why havent PN now got notification of a new higher 5000 profile from BT yet?
They manually tried to change that.. its showing on the portal that they have changed it.. but why hasnt that yet kicked in. **

**May be worthwhile the OP trying a login to the btspeedtest realm again to see if that kickstarts the new higher profile.

I really dont know whats going on here, and why his connection isnt reacting immediately to any increases in the datarate.

But whatever.. its not traffic shaping...
if PN were doing that kind of shaping there would be 10s of 1000s of users screaming about that.
IMHO its something to do with the bRAS >> ISP datarate profile thats capping the speed somewhere.

and wth happened on that line to get such a poor profile in the first place... what caused the Target SNR Margin of 15dB (- that one aint PNs doing). ??
Like I say something weird happened on that particular connection.

-------

btw.. in May this year I got a stuck bRAS profile
- It wasnt the usual brand new max stuck profile - I already went through that in April, and Id already been on max for several weeks.

I had a hell of a time trying to get BT to remove it.. I knew it was there cause I was consistantly flat lining at the same speed.

Raised tickets with PN... showed them tests Id done.. but BTw kept insisting that it wasnt my bRAS profile. I provided PN with shed loads of stuff to back up what I was saying.. they could see I was obviously profiled somewhere.
It was BT that kept denying it... and PN played ticket tennis with BT - who kept chucking it back saying I wasnt. PN kept chucking it back at BT, who would chuck it back at PN saying I was profiled at 8000.. and this went on for several days before BTw finally did something about it.

If you dont believe me.. there will be a post in the PN forum somewhere where I mentioned having had a pig of a time about it.. and I even made a joke about it in there about BT hating me.. cause theyd done it more or less to the day of the anniversary when I first took them on about contention.

In the end it turned out theyd done some work on my exchange the night it all happened... and I later found out Id been reRASed (yet again).
but nope it wasnt BTs fault.. and nope they hadnt wrongly profiled me in a way that it wasnt showing anywhere - - - yeah rite!

In a similar way I see problems cropping up where ISPs are trying to get interleaving turned off and BT are insisting that its off, and refusing to acknowledge that despite users routers showing them its on - and the profile being that of interleaved.
Ive known someone struggling for well over a month now on this.. and Ive also seen tickets from a virgin support agent who was literally tearing her hair out over trying to get BT to believe that yes interleaving was on on a particular line, and can they please turn it off.

So the morale is... that sometimes the ball lies in the ISPs court.. and sometimes it is BT .
How long did it take them to accept there was such a thing as a stuck bRAS profile in the first place?

>>> have seen that said a few times now ...........

this is the sorta thing I get

Thanks Reme8488

This is why I'm trying to sort out the terminology because I can't argue it out with my ISP if I don't know what they are talking about and may end up using totally wrong terminology myself which they can just throw back at me to further confuse the situation.

Thanks very much Kitz:

The crucial thing to me, I think, is the Data Rate.

Having synced at just over 5696 for a good many days, the link from your Site to PN gives a value of 5500 on that page which is why I assumed something was wrong since I believe the Data Rate should be 5000.
PN manually entered this value on 4th October.

With apologies I think the error is not in your referring to this as Data Rate, its that PN must have the wrong value on their page although they seem to insist everything is correct.

They seem to be adamant '..Our system sets it to the nearest 0.5MB increments so with your current line rate a setting of 5.5MB would be correct'.

I assumed this 5.5 MB refers to the page that your site links to ie Data Rate.
Perhaps it refers to Line Rate / Profile of 5696, in which case they may well be correct in what they say.
PN increasing the Data Rate above its correct value ie 5500 as against 5000 could simply be ensuring that their setting of Data Rate is not limiting the throughput.

I suspect that the Profile has never been stuck at BT's end but by my ISP, albeit 'unintentionally', who I have twice had to prompt to raise this value up to 2000 and then 5500. Having synced at 5696 for many days they raised this value on one occasion 'to see if it would make a difference'. The actual values were down to them of course.

NB this all began with a BT cable fault hence the sustained low sync speeds and Profiles referred to initially.
*** If they have increased your data rate you must reconnect before you will see any speed increase ****
They neglected to mention that.
