i went to System Prefrences -> Network -> Wifi -> Advanced -> DNS, then tried to press the “+” button to change my DNS, but the plus symbol is grayed out. All of the WiFi settings are grayed out, actually. It won’t let me change anything, does anyone know how I can fix this?
Make sure the padlock in the bottom left is unlocked in Users and Groups. That will ensure that you can make modifications elsewhere in system preferences. Non-Admin users can't make such modifications. Standard, Guest, and mobile users are such users.
