View source for Setting up a Static IP address on a macOS

==Introduction==

This article provides a short guide on how to configure a Static IP address on a macbook that uses a '''macOS''' Operating System (OS). A Static IP configuration on a PC may be required when:

* Upgrading the router's Bootloader version ('''[[RUT9xx_Bootloader_Upgrade|Bootloader upgrade guide]]''')
* Upgrading the router's Firmware via the Bootloader menu ('''[[RUT9xx_Firmware_via_The_Bootloader_Menu|Firmware upgrade via the Bootloader menu guide]]''')
* You lose access to your router's LAN] network (for example, when configuring Mobile Passthrough mode, Mobile Bridge mode, when you accidentally disable the router's DHCP server, etc.)
* You're trying to connect to another device that has a Static IP address (for example, an IP camera)

Or any other case that you may think of. 

==Set up==

===additional notes===
----
* '''Note''': once you are done with your configurations (the reason you needed a Static IP), you should undo the changes that you made to the computer's IPv4 configuration, because otherwise, you might not have an Internet connection. To undo these changes, go back to the '''Network''' settings window and check '''automatically''' in the '''"Configure IPv4:"''' option field.
