How do you change a network to Private? (Clicking "Change to Private" doesn't do anything!)

Norton 360 is telling me my home WiFi is a “Public network” for some reason. When I open Norton 360, the first thing I see is “We’re restricting incoming traffic on this network.” It gives me two “Change to Private” buttons (one yellow and one black), but neither button does anything if I click it. I click, click, click, and nothing changes.

What’s going on? Why is Norton locking my home WiFi into Private mode?

I have this every now & then, as you say, nothing happens. Going into Advanced/Smart Firewall & attempting to revert back there, also no response. Normally a reboot will put you back to private, you can then change the settings then if you wish Private to Public & back again. If you look into History you should find an early report that it searching for a network.
