Hello KrashKraft, following up to see how we can assist further.

If placing your Netgear between your modem and the Core, you want it in bridge mode. Ideally, you should not use this method, unless you are using a combined modem/router unit. With a regular router only device, it would just be a waste of the router, as it would be doing nothing.
If you place it after the Core, you want AP mode to help extend the range of your wifi coverage if needed.
Ok I’m a little confused. In one statement you said to put my Netgear router in the AP mode and in another line you said bridge mode. From what I’ve been able to read online, it looks like it should be in the bridge mode so that my internet connection effectively passes through the Netgear and then to the Core. My terminology may not be technical, but that is how I understand it.
KrashKraft Another user has the same "direct fiber" connection setup as you have directly connected to the WAN port (one with the blue globe icon) on the Core. No other modem or router used. Theirs works perfectly: https://support.norton.com/sp/en/my/home/current/solutions/v119939113_EndUserProfile_en_us
To setup Core the PHONE being used MUST have Bluetooth BLE capability, most modern phones do. Whether or not you have internet access on the phone DOES NOT matter during setup as Bluetooth is used. You also need to ensure your data plan on the phone is active and has a strong signal. Setup should progress if these are met and you are very close to the Core and remain so during setup. So make sure you have the connections correct and ONLY Core on the network then proceed with a factory reset and WIPE all data. IF during setup Core does not detect an ACTIVE internet connection the issue is with your ISP and/or a personal modem/router not correctly setup.
Cannot connect to the cloud error: Since you had at one point said this error was presented it suggests the use of a personal router during setup: https://support.norton.com/sp/en/us/home/current/solutions/v124387241_EndUserProfile_en_us
IF presently another "personal router" is present on your network, AND you wish to use it and your ISP connection is there, then your personal router SHOULD be setup in AP MODE. Then connected to the Core through one of the "personal router" Ethernet ports since the WAN is already used by your ISP connection.

IF you wish to use a personal router, it does not support bridged mode and cannot get connected : https://support.norton.com/sp/en/my/home/current/solutions/v120684417_EndUserProfile_en_us
IF for some reason you cannot get Connected please give support the opportunity to assist you. http://norton.com/chat

My ISP, not ISO, please pardon the typo.
My ISO is Scott County Telcom and Electronics, in Gate City, VA. BTW, I checked with them last week and they told me that I was wrong when I said that I they use static IP, it is dynamic.
Hello KrashKraft The dev team needs from you the following:
-Who is your internet provider?

I agree with Peterweb it is available during setup. That other thread was about the internal lan settings nothing to do with the address assigned by the ISP. I hate to disagree but it was never confirmed by any employee of Norton.
All: There was a discussion about this earlier in the summer here: https://community.norton.com/en/forums/setting-lan-address-within-core Core doesn't have the ability to have its internal base IP changed. Only the connected devices may have an IP "reservation" assigned per the 3rd octet settings. 
Cheers
The setup of a Static IP from the ISP is only available during a factory reset of the Core, as noted in the WAN settings link given by SoulAsylum above.
So if you are experiencing some issue with the Core connecting to your ISP's Static IP, you will have to reset the Core to factory and go through the setup again.
KrashKraft I obviously missed this statement in one of your previous posts, which is the crux of your issue;
I use the static IP address as assigned by my Isp provider.
Since you are using a static IP from your provider here is an official article on that subject. Please look under this section "Why can't the WAN settings for Norton Core router be changed". https://support.norton.com/sp/en/ie/home/current/solutions/v120922407_EndUserProfile_en_us
To date under firmware version 213 I haven't seen any onboarding setup for Core where you can mirror your static IP assigned by any ISP within the Core as it doesn't support that in its current form. Core DOES allow you to set a static IP for DEVICES within Core and ONLY the third octets will be allowed for change. Firmware release notes are here:
https://community.norton.com/en/comment/7733231#comment-7733231
Although you state Core has functioned before, I personally don't see how that could be possible without having the ability to mirror your ISP IP address on Core. Core has no way for its DHCP to function since it isn't getting any data signals from your provider.
Cheers
I’m afraid that I may have confused you. The router that I was referring to is my Core router. It is the only device that I have connected to my Internet cable. There are no other devices in this setup.
KrashKraft Your phone app will access the Core preferably with Bluetooth. It will also access the Core using your cellular data. Just so you understand, there is no confusion on my part about what you are conveying. I have the Core and access it remotely daily off site. 
Power cycle your router and power DOWN the core, leave the core down and reboot your router. Wait 10-15 minutes and power the Core on. Recheck for access.
Earlier: Hello KrashKraft Concerning "cannot connect to the cloud", here is the official solution: https://support.norton.com/sp/en/us/home/current/solutions/v124387241_EndUserProfile_en_us
This is the reason you do not now have internet access. Your ISP signal isn't being detected by the Core. " I don’t have a modem, nor do I have any kind of switch. My internet comes from the ISP via fiber optic to a box on the outside of the house. From there it’s hardwired directly to my router".
The commonality with your setup, although working in the past is that something between the core and your router with the ISP signal has changed. Directly check your internet connectivity on your router Ethernet with a wired connection to a laptop or computer to validate you have a signal. If so then your router SHOULD be setup in bridged mode to the Core through one of those Ethernet ports since the WAN is already used by your ISP connection. Nothing else should be connected to your Ethernet on the router other than Core. Other connections should go through the Core LAN ports. Hoping this all makes sense to you.
Cheers
I have no idea what the firmware version is now. I am unable to access the router to see what the version is. As I stated earlier, I have no access to the internet with the Core router, nor I cannot access the router.
Hi,
Please try to reproduce the issue with the latest firmware update (v213) and check if the problem persists. Thank you.

Thank you, I'll give a try when I get the time. To be honest with you, I've become quite discouraged with the Core.
KrashKraft Best advice I can give is give support a shout. http://norton.com/chat
