I just bought a SB8200 to replace an older arris modem, and while my wifi is working, nothing on my hardwired network is connecting. 
 

I have the modem connected to an 8 port switch, and then router is connected through the switch, as well as my Apple TVs and Hue bridge. The router is getting signal and the wifi works fine but the other devices can’t connect. 

SB8200 is just a cable modem so this modem can provide only one IP address for one LAN port it doesn't have option to split the IP address to provide multiple IP’s as router so you need to setup modem LAN port  → Router WAN port ,  Router LAN port  → Switch LAN port then you can get all the ports working on the switch.
