Hey mkgraham,
Looks like other Community users did not chime into your discussion. Apologies for the delay on a response. It sounds like you previously had an IP passthrough setup with your Hitron modem with a 3rd party router. The BlueCurve Gateway does not have passthrough capabilities, if you are looking to improve your range of connectivity, we do have Blue Curve Pods available which will create a mesh WiFi network.
Cheers,
