Gigabit Switch - Only One Port at a Time

Looking to understand what configuration issue I am having.  I have a CM500V modem feeding into my GS116v2 switch but only one port works at a time.  Therefore, I have lit up one port into a mesh WiFi network which as sufficied but I would like to also have some other devices directly connected into CAT5 ports in other areas of the house.  Which means I need the switch to actually light up other ports.  Any insights in configuration settings would be great.  I assume it is with the Netgear configs vs my intertnet service provider.

    Afraid no. A cable modem does issue only one (typically public) IP address [that's an ISP limitation - but almost standard]. Adding a switch alone does not help. The problem is the lack of a NAT router in your set-up, which does handle a local network for LAN and WIFi, providing a private LAN subnet to multiple local devices, and the related Many-to-one NAT.
