Orbi and ISP router/modem and configurations

If the router/modem is truly in bridge mode, then it is not involved in handing out DHCP leases.  The DHCP lease would come from the ISP's DHCP server in the cabinet down the street or in their central office, unless your ISP doesn't use DHCP.  More about this below.  

 

Is your Orbi obtaining a public IP address for its Internet/WAN port?

 

Do you see anything in the logs maintained by either the Orbi or the router/modem that might shed some light on the disconnections?

Orbi is getting some sort of IP from the internet port, and looking at the log there is mention of a DOS attack in the time where the internet went out the first time, but the second time it just seemed to lock up on me and I had to hard reset the router to get it working.

The ISP is providing the bridge/router with a static public IP, should I get that changed as well?

Can you explain more?  The modem/router is manually configured with a static IP?  Does it still have this IP address in bridge mode?  Does your Orbi has a different public IP?

I'm a bit out of my comfort zone with public IP stuff, so I hope this makes sense: My ISP recommended me that if I had their equipment in bridge mode, they would provide me with a static publiv IPv4 address. I can see in the Orbi settings that it is getting an IP from the ISP router/modem which is 185.x.x.x and then I have my local IP that the Orbi hands out in the 192.x.x.x range.
