hi, since the 1st august my broadband started to play up, it started dropping to 2meg then it would go up to 4 then six and then it would do the same again. I used to be able to get 7meg on my line untill this started happening. After ringing India and reseting my ip profile it seemed to be a bit more stable but it only stayed this way for a few hours. A few more days into the problem and my speed dropped to 130kbps which is totaly unusable and my ip profile was 135k, i rang India again and they did there usuall b------s and reset my profile again. After a few hours my speed became unstable again and dropping 2meg then 4 and 6 and back to 2meg but never my 7meg that i had since i first plugged in the router at day 1 of my contract, i didnt even have to wait for 10 days training because it was 7meg and stayed at 7meg after 10 days.Oh and i never had to wait for my ip profile to gradually raise itself,after 10 mins of India resetting it would be 7150k which is back to full sync speed, i should of mentioned earlier that my DSL connection rate never changed, it stayed at 8128 down stream and 448 up.I had an engineer come out to my property and change the master socket and re wire the junction box and he took the good quality nte5 master socket with him when he left, im so peed about this because the new master sockets are so cheaply made and are so **bleep**, my phone line now buzzez constantly when the router is plugged in, before he messed with the wiring it only buzzed when the router was receiving or sending data while i was on the phone, also the buzz is a lot louder now besides it being constant aswell, so if you have an nte5 master socket from 1980s,1990s, with the test socket dont let the engineer take it away because beleive me you will want to put it back on after hes gone, my line was perfect like i kept saying on the phone to india "my line is ok im syncing at the full rrate that my line can handle and i dont need the engineer, the engineer need to check outside ,the green box and the exchange" but he never did any of this he just came to f--k up my line.Sorry got carried away there back to the problem, after another 2 days of waiting for speed to go stable it dropped back to 2meg and i rang India and went through the do, ip profile reset, didnt have to wait for it to build up because my sync rate never changed from 8128 down steam, now on the 15 August my speed dropped to 130kbps and profile went to 135k and this time they cannot reset my profile it is stuck at 135k my speed is worse than dial up at least with dial up it was stable, the line cant even produce a stable speed at 130kbps even that keeps dropping to zero and going back up. Now ive got to wait for another engineer to come out and do what the previous engineer did and wont do, im just going round in circles.I was going to leave on the 12 August becuase of this problem not being properly addressed but got talked into staying and renewed my contract to a higher speed because apparantly my exchange has been upgraded, what i dont understand is they coouldnt offer me the 20meg speed when i first joined this year and i was told that the upgrade was done a year ago.Im supposed to switch over this friday on the 19 August wgicj=h is the same time as the engineer coming out, i feel as though ive been ripped of to the max and that there not going to look for the problem untill the switch as been made so that means being stuck at 135k even after the switch because that engineer is not going to resolve it by coming to my property. Im feel such an idiot for being talked into a other useless contract which is now going to cost me more to get out of, at least when i do go to a different isp they will actually get of there **bleep** and do something.
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems) http://speedtester.bt.com or http://bt.custhelp.com/app/answers/detail/a_id/9354/c/346,4740,5520 and post the results . but you may want to wait until engineer has been
are you connected directly to the NTE5 master or test socket or to somewhere else? Do you have any phone extension sockets in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem
As I understand it, the IP profile gets reduced automatically based on disconnections not sync speed - so if you are constantly plugging and unplugging your router (or turning it off and on - possibly, although I think the exchange is supposed to be able to recognise this as a power down not a disconnection I'm less than convinced) then it will be reduced as the line is considered "Unstable" even if, when it reconnects to the exchange, the router is able to negotiate a higher sync speed with the exchange. So even if your profile is reset, once you get a few disconnections it will drop back down automatically.
This may be being caused by whatever is causing the buzz - a new bit of electrical equipment in your house (Sky boxes are quite prone to this I think) or the neighbours, or a washing machine or central heating pump that's on the fritz? There is supposed to be a way of finding this type of fault by using an AM radio tuned to 625MHz and if something gives a burst of static on this frequency at the same time the hub disconnects it is likely to be the culprit. This is known as REIN and is notoriously difficult to locate. It is equally possible that the fault lies on the BT line proper but until you sort it out then you will have to deal with the IP profile you get.
Once the underlying problem is sorted then your IP profile should slowly climb (requiring between 2-5 days of stability to recognise the situation has changed) and it would be reasonable to request a further reset at this point. It's possible that your agressive insistence on IP profile resets before correcting the actual problem may have caused BT to request their customer service advisors to block these requests as they have so far proved worthless so you may have to be very, very nice to them.
it would help if you could provide the information I requested as it will help the forum members provide assistance/help otherwise eveyone is just 'shooting in the dark'
it certainly sounds like a noise problem but more info is required
The IP profile's not reduced because of disconnections. The IP profile will always be the value of a certain figure depending on what the sync speeds are.

It tshould take up to 75 minutes for the IP profile to be reduced accordingly. The thing thats reduced is the Sync speed if the Dynamic Line Management sees instabilbity on the line then it will raise the target SNR (noise) margin in steps of 3dB ie 6dB, 9dB, 12dB, 15dB. Which then quells the speed to make the line more stable.
As with the 88.2% new profiling system on 21CN (ADSL 2+) it will reduce and increase immediatley with the sync speed. So if your sync speed is 3782 your profile will 3336(rounded to nearest whole number).
the key words are 'up to' 75 minutes - most times it is far quicker than that unfortunately new system is far better
