I forgot to mention the method of debugging this modem and producing the log:

Being a programmer myself I used the logging functionality of the cable modem as a "debugger" by using the refresh F5 functionality of the webbrowser to get a constant update of the log (like stepping through code, this will show what the modem is doing step by step), and using the back button of the browser as a breakpoint. The webbrowser apperently remembers the last successfull transmission of the cable modem/websites/webservers. Firefox was used for this.

Exact method is as follows:

1. Connect modem as usual.

2. Power on modem.

3. Reset modem

4. Surf to http://192.168.1.1/AdvEventLog.asp

5. Keep pressing F5 until the log disappears/connection reset message.

6. Press back button of browser and examine last good log.

Bye,
