I don't use linux mint (or them ppas) but in debian sid and ubuntu bionic I'm unable to reproduce issue with wifi settings. I'm using cinnamon 3.6 from official repository. In debian/ubuntu cinnamon packages there are 2 network patches not still applied upstream (so that could make the difference), in particular https://github.com/linuxmint/Cinnamon/pull/7118 that FWIK should solve this. Can you test if this issue is still present with bionic cinnamon packages and report if issues are still present please?
