Fortunately I was able to find the solution.

The "Nighthawk Mobile App" overwrote security settings and applied the Wireless security. It also let me restore all three radios as needed.

I still do not know where the Invalid IP Address error came into play.

Solution: If you find errors similar to the 'Invalid IP Address" error, I recommend trying the mobile App.

What gave you that message? A wifi client? Something else?

You changed the WPA/WPA2 encryption. Do you mean Security Options in

Wireless Settings?

I have a fair number of firewall rules so don't really want to have to redo these if I wipe the router.

Where? There aren't any firewall settings you can change in the router. Do you mean something else?

What firmware version do you have on the device?

A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.

It might also help if you told people what the modem is in front of this router. The model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?

Apologies for all the questions. But you can help people to help you by providing the information suggested in this forum's header:

Model (Recommended - Helps the community give the best answers)
Body (Include additional detail including model version, firmware, OS and environment where relevant.)

They are there for a good reason.

this was the response from the browser (chrome, IE, etc.. from multiple computers as mentioned)

As mentioned, I made no initial changes. I logged into the router and the 2nd 5Ghz radio had WPA/WPA2 enabled (it was not prior). When trying to fix this and apply the change is when I received the notice)

I enabled port forwarding and about 20 rules (which apply to rules to the firewall).

What firmware version do you have on the device?

Firmware Ver:

Firmware Version	V1.0.1.12_1.0.41

GUI Language Version	V1.0.1.12_2.1.46.1

A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.

The modem is an Arris SB6183. It is fine with the typical 192.168.100.1
