FYI you can read the status of the Ambit directly at:
http://192.168.100.1/
...but you'll need to log in as 'root' with a password of 'root'.
Some pages are hidden - as a quick 'view source' will reveal. For example:
http://192.168.100.1/P_log.htm - is an event log
http://192.168.100.1/P_rate.htm - gives interface stats
http://192.168.100.1/P_ubd.htm - gives upstream burst info
