How can I prevent "Reset network settings" on my iPhone from affecting my Laptop? I just hit reset network settings on my iPhone (9.2.1) because I was unable to make phone calls. 

I then noticed that my OSX (10.11.3) lost its internet connection.  I immediately checked the keychain (where all wifi passwords are stored) and noticed that all passwords are missing.

I can only assume that resetting the iPhone "network settings" also affected my mac.  I assume this occurred through iCloud. 

Question


How can I get those Wifi Passwords back?
How can I prevent this from happening again?
Check to seen if your passwords still exist under Safari &gt; Preferences &gt; Passwords on your Mac. Maybe they are still there.

If this doesn't work, try the following: Unplug your router's ethernet cable (so that iCloud cannot sync with the server) and try to restore your from Time Machine. This should revert your Key Chain. I recommend disconnecting your router because if you just turn off your wifi, it will probably turn back on after the restore is done and sync with iCloud again.
