11.7 Activation and Stop of Network
While operating the system, you may need to stop and reactivate the network device as needed for various reasons, such as an error occuring or changes to the configuration. If the existing device is stopped, the network connection is disconnected, and the IP address that was previously assigned can not be used. When the connection is stopped and a new connection is made, the network connection is made according to the latest setting contents.
You can use several commands to stop and reactivate the Raspberry Pi system. Let’s look at each command one by one.
