After installing norton 360 on my mac I've noticed that the program keeps changing my home wifi to untrusted network from trusted network. I've searched for others who might have been having this issue but the instructions for fixing refer to a firewall general setting that the mac doesn't have so I'm guessing that is for windows users.
I just checked, and it was doing it on 14.4, also.
I've been having the same issue since yesterday. did you recently update your macOS? This started happening to me right after I updated to Sonoma 14.4.1, so im wondering if it's a glitch related to that.
