  1. yes, all the lights should be doing something. https://arris.my.salesforce-sites.com/consumers/articles/General_FAQs/SB8200-LED-Light-Status/?l=en_US&fs=RelatedArticle
  2. You can’t go directly from modem--->unmanaged switch. You have to go modem---->router---->switch  
  3. even through the sb8200 has 2x ethernet ports, most isp’s only provide 1 public ip address. Meaning that only 1 device can be directly connected to the modem.

Are the led’s disabled?

Also I just wanted to say , if I power cycle the modem , all lights will show solid except the internet light , it will flash for a moment then all lights go out except the download light

Have you reprovisioned the modem with internet service provider?

Also, I suggest you check the IPV4 address.
