After the first 5 months of excellent performance, I now have this problem of having to re-configure the product every time I power-on ! To try and solve problem, have re-installed my OS (Windows 2000 Pro) twice, re-installed the modem with the ZoneAlarm Firewall disconnected, and changed the USB port - all to no avail. The modem model is ZyXEL Prestige 630-C1 and the driver supplied is CWA.1.2.H0
Problem first started when I installed Epson Stylus CX6600 (a MFD), but now persists even with the printer uninstalled. I thank you ahead for your much needed help.
