Weird connection issues, advice needed!

I’ve been on ADSL Max for 2 years with BT Retail. 2 Weeks ago I became an ADSL24 customer, and that was also the date my connection became worse than I could have ever imagined. However I am looking beyond that huge coincidence in the hope that there is something else I am missing.

Basically, my internet will connect at 4-7mb with a normal SNR for a few hours, then for no reason at all my SNR will drop to a minus figure and my connection will drop with it. Most of the time I cannot reconnect when this happens, I have tried resetting my router and I have left it trying to connect all night with no luck. I have found the only way to connect is to pick up my phone while it is attempting to connect (figured this out after phoning tech support asking why I couldn’t connect).

After I finally connect the speed I am connected at is normally between 100-500K, and no amount of reconnecting will raise this. After this initial disconnect I will often have as many as 20 net drops over a period of an hour, destroying any possibility of raising my IP profile beyond the minimum of 135K. However quite strangely I can upload at the full 832K most of the time.

After a period of a few hours to a few days, my internet finally allows me to connect at 4-7mb again. However just as I can pick up my phone to allow me to connect to the internet, this also causes the opposite effect. If I pick up my phone for even 2 seconds my SNR will drop into the minus and my connection will go down.

One of the strange things is that my downstream attenuation has always been exactly 40.0db, except when I’m in the middle of one of these periods of madness when it sits at 43.0db. It is also worth mentioning that I hear static and crackling on my phone line most of the time.

Every time I phone ADSL24 tech support they do a line test and determine there is a fault on my line, they then file a fault report with BT, and BT blame it on various things which so far have included ‘core network fault in your local area’ and an ‘IP network fault’. I am informed that an engineer has fixed the problem, my line is reporting no problems, and my fault report is closed. Within the next few minutes it’s pretty obvious that the problem is far from gone. So I phone back ADSL24 who do a further line test, determine there is a fault, and round again I go in the circle.

I have tried 2 other routers, I have tried removing my phone altogether, and I am now using the test socket all of the time.

The only thing BT can offer me now is an engineer visit to my home which they will charge me £160 + VAT if the problem is not part of their network. I really cannot afford this as I am a student on a very tight budget and I just cannot afford to take the risk that they will charge me so I’m totally out of options. Having a permanent IP profile of 135K makes it impossible for me to use the internet for the purposes I pay for, and I have no chance of seeing that increase while I have these problems. Do I have any other option?
 
Sounds like you've got some physical fault with your line somewhere - it's extremely unlikely to have anything to do with you migrating.

If you've tried the test socket, with and without filters, and tried another modem, there isn't much that a BT visit could blame you for.
If there's crackling on the voice service, you might be better reporting that first and hoping it fixes the problem with your ADSL.
