Update - When in modem mode the router was saying no DHCP. So I reset the SH3 to be a router and connected all ethernet cables directly into SH3.
Everything worked fine for a few hours, all devices connected via ethernet worked fine. And now they are all not working.
The attached devices show as having a reserved IP address in the DHCP settings, however the devices are saying no DHCP?
Is this something my side or do i need to call VM?
TIA
