Reset Network Settings on Mac
While iOS provides an option to Reset Network Settings on iPhone, there is really no option in macOS to Reset Network Settings. The only way to Reset Network Settings on Mac is by manually removing the faulty WiFi Network or Ethernet Network and creating a New WiFi or Ethernet Network on your Mac. While a Network Settings Reset does not erase any data from Mac, it does result in all your current Network Settings, Network Names and Passwords being removed or deleted from the computer. Hence, make sure that you note down your WiFi Network Password and VPN Network details, before going ahead with the steps to Reset Network Settings on your computer.
