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. 

Thank you … Any thoughts of why the other lights are off ??  Also I did test the connection without the switch connected to the modem and I do have connectivity But still only the download light is active 

Is it working? 

Are the led’s disabled? 

Yes all my devices are working and I can get online But still only the download light is on .

I don’t know if the lights are disabled , how can I check that ?? 

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.
