Telstra Smart Modem Gen wont see Hassio on virtual machine after modem lost settings

Hi,
I have been running HA Hassio under as a virtual Machine on Windows 10 for years with no issues. We just has a major power and internet outage for several days and now my modem has lost all its settings…
The main issue is my modem wont assign an IP address to the virtual machine.
The virtual machine is running and still has correct IP assigned when it starts up, how can I force the modem to see it?
