I had a working BCM 400 3.5 and needed to change numbering plan. Through the serial port I logged on and initialized the system. Now I cannot connect through the web browser ('page cannot be displayed'). Browser was working fine before I initialized. I can still logon through the serial port with default login/password. I verified the IP addresses and can ping them, but browser access does not work. Everything else seems to function (dial tone, etc.) Any ideas why or how I can remedy?
