i have just gone through the exact same problems on mine and , touch wood , all has been resolved . First of all you need to contact BT . I tried on numerous ocassions only to be on hold for over 45 mins sometimes . I then found that even when i did get through they did diddly squat . In the past when i'd had a problem an engineer came round and left me another number ( it's a pay one though but only national rate ) so i tried it , they were the dogs bits . helped me every step of the way calling me at least 5 times at home to check on progress .
Before they started they told me there was an update patch for my ADSL modem (BT Voyager Mk1) which increases stability on 1Mb broadband , something i'd never been told about .
Step one was to change micro filters and try again.
step two was to disconnect everything else but for the pc from the phone line (phones , answer machines and in particular Sky Digital if it's connected can be a real nuisance they said) and try again.
step three was to unscrew the face of the main incoming phone socket (where the line actually enters the house not any extensions) and inside is a test socket , connect directly into that and try again . For me that involved lugging the pc half eway round the house but it's a process of elimination and if they come out to you and find it's an "in house" fault they charge you .
If all these fail then you tell them there's no improvement and they do all the exchange and physical checks . Mine turned out to be a faulty line connection that had got "weather" in it as they said .
I don't know if i'm allowed to but the 'alternate' phone number on her (forum rules?) but if it's of any help i still have it .
If anyone else has a 'BT Voyager USB ADSL Modem (it's Mk1 if that's all it says ) then the patch can be found at ;
