invalid IP address on my cable modem

Mine assigned 96.29.42.82 but my router, access points, or my computer alone don't recognize it. 

Are you getting this IP address on the device connected to the modem directly or using router? like on the device connected to wifi network.

I replied back on your other post on this topic. “If you connect to the S33 directly from your PC and navigate to 192.168.100.1, what happens? What are you using as your primary router? The S33 is a DOCSIS 3.1 cable modem. It looks to me like the Unify USW Lite 8 is actually a POE unmanaged switch. You need a router to handle DHCP, etc.”
