I am looking to re-configure a 877 router for ISP migration. However, I seem to have a problem doing this remotely. Currently the Cisco 877 has a static IP address assigned to the dialer1 interface. Once I change this to "ip addess negotiated", the router kicks me out and I cannot even change the username/password details to reflect the new ISP on the dialer interface.
Apparently there is a way of changing the details remotely but everytime I try it, it kicks me off and then I cannot reconnect.
Any ideas would be appreciated please.
