I'm on 20mb bt broadband , I was reviving 5mb dl speeds untill day three, for the three weeks after that I've been getting 1.5 mb download speeds. Also when i start a call of my landline my routers Internet goes off, ive tried swapping Adsl filters and everything........ Edit , dam iPhone spell checker
 
I'll go with "you've had loads of line errors, possibly due to a line fault.. the DSLAM has interpreted this as unstable and lowered your target margin to increase stability".

I bet you the noise margin is now 15dB, and you'll be stuck at this speed for a few weeks / until the fault it fixed.

Try a phone at the master socket. If you can hear noise, call 151 and report a voice fault.

Yeah I hear noise but only when sum1 speaks , verry crackley. I have rang bt and they say my line should handle 7 meg and they will try and fix it , am debating switching to infinity , thanx for your post

People saying about line stats, when I go to that ip it's my routers cp, I see no "line stats"?

I found this in event log tho

Line stats are there in log

3.70db up and 6.80 db down.
176kbps upstream and 3kbps downstream

shows your router synced at 3mb. Noise margin of 6.80db is about right for your line speed at the moment.
Thing is its within BT's acceptability so it be difficult to get anything done without constant pressure.

For 7mb you really need a noise margin of about 14db to 15db. Looks like there was or is some issue on your line so the exchange has retrained your line (hence disconnections) to a lower speed and noise margin to compensate.

Anything lower than a 5db noise margin then BT may do something about it as 6db is ideally the lower limit before the line is really unstable.

I take it your master socket is not the new NTE5 with inbuilt DSL filter ? Ie a seperate socket for DSL and a seperate one for phone ? Could be something simple as dodgy wiring in your master socket. Also what sometimes happens is the grey box on the outside of the wall where your wiring comes through can let rain in and cause issues.

What you need to do when reporting it to BT is mention the noisy line when speaking and that your internet speed has dropped from 7mb to 3mb and keeps disconnecting and say your noise margin keeps dropping below 5db (even if it isnt)

Rite ok thanx do I've done that now and am awaiting a tekki , rite now bt is been helpfull , or seem to be , they assured me ut would b resolved today anyway.. But we shall see
 
They will send a phone engineer, to fix the voice fault.. so you should play on the fact that the line is making noises when you are on the phone.

Don't mention broadband unless the engineer asks. BT have separate engineers for each, so a mention that "my broadband is slow" will mean he may not even attempt to go up the pole or to the cab to check, and will fob you off by doing the simple HAWK test at the master socket, thinking he isn't equipped to diagnose it.

The upshot of this, is a fixed voice fault usually means a fixed broadband fault :)
 
Rite, ok so basically if this guy just shoves summet in my line and runs a test and says he is done , I want more? That's all they did when they installed my broadband
 
Yeah like EVH said play on the noise issue on the line affecting voice calls. The test you described is what a broadband engineer does not a voice/exchange engineer.

Also take a note of the van that comes it should be BT Openreach.
