EDIT: Solved. Disable residential gateway function and put the Airport back into regular DHCP/NAT mode from bridged. Well, this is a weird one. I've got my Airport Extreme basestation (802.11ac) setup in bridge mode connected to an ISP provided cable modem (Hitron CGNVM) that has routing capabilities. Everything has been pretty fine until I started adding Ring security cameras (doorbell pro, chime pro and floodlight cam) to my network. I've gone through a lot of troubleshooting with them but haven't been able to figure anything out yet except that their products seem kinda flakey. So the issue, from what I can tell, is that they don't like connecting to my bridged AEB. I can connect them fine to my iPad Pro in hotspot mode. What's even weirder is I had everything setup and working fine with all three devices (although initial setup with the doorbell and chime was tough and required customer service help), though things started acting weird a little while after I added the floodlight cam earlier last week. Then the chime went offline along with the floodlight cam at the same time (according to support logs) and the doorbell has stayed online without any issues (which is really confusing the Ring people). What I'm trying to figure out is how to connect the modem/router thing to my AEB, but have my AEB handle DHCP because I think the issue might be with that? Although I might need a static reserved IP address set up for the router to the AEB? The problem is that I have to use this modem/router thing because when my wife expanded her daycare last summer, we got everything officially licensed (required for the expansion we were doing in our state) and the fire marshal requires a home phone line, or cable phone line with battery backup (which we have). So their special modem is connected to the house phone system for only $10/mo and we never use it, but they do occasional inspections so we can't get rid of it unless we want to spend $60+/mo for AT&T home phone outside of the cable providers. And before this I would buy my own modem (Motorola Surfboard DOCSIS 3.0 with no router built-in) and never had problems. I've got the router/modem thing configured with the WiFi turned off because it's garbage compared to the beamforming range of the AEB. So I guess I'm trying to figure out if there is some way to pass the AEB the unrouted connection from the Hitron without fouling up the phone line stuff that the box has to do? Otherwise if I have DHCP turned on with the modem, I run into a lot of issues trying to play things like Xbox Live and other glitchiness (I think it was giving me double NAT issues or something). Thanks!
