I have recently upgraded from a diaup internet connection to a broadband connection, using a new external USB broadband modem, which is an excellent improvement. However, I work from home and, from the same machine (running XP Pro) also dial in to my customers' systems using the original internal dialup modem and a different physical phone line. I can dial in to a customer's site and do my work whilst remaining connected to broadband, but am surprised to find that this causes my broadband service to hang i.e. I can no longer visit websites or send/receive e-mail. Is this usual? Is there anything I can do to resolve this so I can continue to send/recieve e-mail on the broadband connection whilst simultaneously being dialled in to a customer site?
