How to restart network services on Sierra?
On FreeBSD/Linux, it is possible to restart network services by restarting a daemon.
Is there something similar in macOS Sierra?
Solution 1:
You can tear down and start up the network interface using:
sudo ifconfig en0 down
sudo ifconfig en0 up
Solution 2:
Network interfaces can also be Disabled & Enabled in System Preferences‑Network.
Solution 3:
The restarts Wi-Fi without sudo. Does anyone know how to do this with a single command?
networksetup -setairportpower en0 off
networksetup -setairportpower en0 on
