I had a similar experience when first getting upgrade to BB with BTOW,
although I could occasionally connect.
It turned out to be a line fault, but it took about 2 weeks to eventually
get an ADSL engineer out to sort things out.--- He connected me to a nice
new underground cable and it's been fine since.
The phone line worked OK, but the ADSL was irregular, finally going off
totally.
It seems that the ISPs and BT will only send out someone who knows what to
do with ADSL faults as a last resort, in the meanwhile, they waste customers
time & feed them a string of false solutions.
Read about it on ADSLguide here.
