Connectivity problems
Turn off all other gadgets when not in use, keeping only the fiber box and router connected (it handles Wi-Fi). Ask yourself which device you’re using for Wi-Fi and how long you’ve had it. Do you have a spare Wi-Fi router available for backup? If not, it’s hard to confirm if the router inside the fiber box is the problem. Connect just the fiber, Wi-Fi router, and try one device at a time for fifteen minutes. Gradually add more wireless devices, testing each session for ten to fifteen minutes.
It seems you're asking about identifying whether your device has a globally unique IPv6 address. If you visit https://whatismyip.com, it will show your public IP address. Generally, public IPs are version 4 addresses, while local networks use NAT. For devices inside the network, you should clarify with your ISP what this setting means and check if it poses any security concerns.
