Ok, long story short, this isn't something the user will be fixing from what I see.
This is a remote configuration for the most part.. and the tech will need to visit.

  • This isn't the normal fibre coaxial AVS... This is over DSL.

From what I saw there is some configuration in the modem and the cable box.

SmartRG modem: So everything starts from the modem > Interface Grouping



Cable box settings, network settings > Internet > DHCP


After you restart it should scan for channels and pull those subnets, etc
