To be honest there is no need for the GUI on the modem, except for changing the IP address, and wasn't there a telnet method for that?
There is a telnet method that works - I have tested it.
However, it doesn't survive a modem reboot.
It is something I could build into the resync procedure though, to initially use the default 192.168.1.1 & then apply the IP address as specified in the ini file & use that.
I think that changing the IP address causes an 'on the fly' resync though (from my vague recollection).
If that's the case, there would then be 2 resyncs in quick succession at each resync.
DLM might not 'like' that happening too often & as we know, it can sometimes appear to be over aggressive.
