I have noticed that when you run the set_hg612_date_and_time.exe, it appears to use IP address 192.168.1.100, even though mine is configured on 192.168.1.150.
I presume you mean this:-
User Name : admin
Login IP : 192.168.1.100
Login Time : 2015-03-16 21:44:50
Login TimeLen :
That confirms that you managed to login to the modem.
The Login IP should be the IP Address of the PC used to login.
It should be part of the entry in the file named
Login_events.TXT, which should be stored in the
Event & Error Logs folder.
In the same folder, amongst the other event/error logs, there should also be a file named
SET_HG612_DATE_AND_TIME.LOGThat file should have contents that look something like this:-
16/03/2015 21:44:49.942 - Start of SET_HG612_DATE_AND_TIME.exe

Have you now managed to get it all running?
