Hi peeps, I am new here and I guess you know I am having problems otherwise I wouldn't be here!
My connection speed has gone down and down since joining Orange a few months ago. I was promised 4.5 Mbps which I got initially during the warm-up period. It eventually settled at just over 2Mbps which I can live with. After quite a few complaints though (since this is well below what they promised me) they said my line would only cope with 2.5Mbps.
Anyway, now it is 0.1Mbps!!!!! and has been for a couple of days. They told me there was a general speed problem country-wide that they are working on.
the BT speedtest shows my IP profile is 135kbps. What does that mean?

My main BT socket is a dsl filter so I don't think it is my wiring. When I unplug the bottom half of the socket everything else is disconnected. Using this system I don't even need any filters.

From stats you are on IPStream Max not LLU.
You should be able to get good speeds but your stats:
Type : Interleave - Some type of problem with line
Noise margin (dB) : 15.3 - Too high
Attenuation (dB) : 45.0 - You are not that close to the exchange
While a high margin is good, on an ADSL max connection margin over 6 can generally be considered unused potential speed. The system can however increase the target level for the margin if it detects problems and beleives it will stabilise them. Usually it pushes the target up in 3's. Default first followed by best order for sheer speed, 6, 9, 12, etc.
On this occasion the margin is relatively unimportant as you have a relatively good sync speed of 4384kbps and it's the profile system that is limiting the speed to practically the lowest level. The margin, along with interleaving being on and the low profile all point at some root problem.
Do you get many disconnections?
Does the downstream rate in your stats vary much?
To get that low generally something's making the system think it's unstable and thats usually one of the two options above.
Providing the downstream rate stays stable around that level, you don't get any disconnections then it should raise the profile back up within 3 days.

Thanks everyone this is all very useful information.
Elhana, so I presume it is a bad idea to reset the livebox to try and force a better sync rate since a) the sync rate is not bad anyway at 4ish Mbps and b) the adsl max modem at the exchange would see the disconnection as an instability?
But then how does the system cope with people who turn off their modems/liveboxes when not in use?
In answer to your earlier questions, I don't think I get regular disconnections although sometimes if I look at the livebox web server it will say tat the conection has only been active for a few hours or so. Normally though it is a few days.
The downstream speed has been stuck at 0.1Mbps for 3 days now but I have reset the livebox several times in that period. Prior to this recent abysmal rate it varied between about 1Mbps and 2.8 Mbps.

It's at times a double edged sword. A re-sync can help when you initially had a low sync, the system has safeguards to cope with single one off fluctuations. However in your case it's not worth it as it's not using the available sync speed you have.

Well there are negociated disconnections and real disconnections. Just turning the box off or unplugging the cable would be counted. Details of exactly what the system regards as a disconnection and then what determines it's unstable are very sketchy, they apparently keep the exact settings of the system a secret. Generally though a disconnection followed by a reasonable period of total inactivity, like turning off overnight, I'd expect are probably discounted.
