I have been asked to help a friend who has just had BT broadband installed. He is on a VERY long line so does not expect a very high speed but apparently it works OK except when he answers an incoming telephone call, whereupon the router loses its sync with the exchange and takes ages to re-establish a lock again. As long as he does not answer the i/c call, it's OK. I'm going to visit this weekend and would like to go prepared, so any suggestions please ? He has got a laptop with Win 7 and he uses it with a wireless link to the router. I strongly suspect wiring or filter problems but any contributions gratefully received. It's rather a long way to go and find I've left the **** at home !
