ok, im at a loss sorry i cant find anything i could ask around, one of my mates knows more about PC probs but its too late to phone him.
I did a bit of digging on yahoo, and it seems that the bt voyager
shares itself with the phone line, and so could be people in the household picking up the landline or the handset has not been replaced.
On a side note, a friend of mine uses BT Openworld and his internt kept disconneccting, he got an engineer out who finaly came and told him his lines were rusty and so they (BT) had to replace them (free) now he has no known probs, but he`s using the Speedtouch DSL, thats why i asked you.
other than that im sorry i cant help you any more, unless my mate knows something i dont, if i find out, ill try post back
