Wi-Fi indicator error after bad chown command I mistakenly ran chown -R /.

Subsequently, I reinstalled the OS from the recovery drive (10.12.6) and ran everything I could find on the internet, including diskutil resetUserPermissions (id -u). Things are functional for the most part. However, every once in a while I hit a bizarre problem that seems to be related to permissions. 

This one is the fact that my Wi-Fi indicator is totally wrong. Right now for instance, I'm on Wi-Fi in a Peet's coffee and the indicator is the exclamation point over the Wi-Fi symbol. Clicking on it says no internet connection. No networks appear in the list either, anywhere I go. I'm able to list networks and get online in Terminal but the commands are pretty unwieldy. Does anyone know why this might be the case?
Not sure what the issue was, but it was blown away by an upgrade to High Sierra and the wifi indicator is working again.
