Connect to the internet using DHCP in AirPort Utility on Mac
When you use AirPort Utility Setup Assistant to set up your new base station or extend an existing network, it automatically configures the best settings for your network. Itβs recommended that you manually configure your base stationβs settings only if instructed to do so by your ISP or network administrator.
That said, if you know that your ISP provides an IP address automatically, you can configure your base station to connect to the internet using DHCP.
Open the AirPort Utility app
on your Mac, located in the Utilities folder in the Applications folder. In the graphical overview, select the base station you want to configure, then click Edit. You may need to enter a password for the base station.
Click Internet, click the Connect Using pop-up menu, then choose DHCP.
Important: Donβt modify the DNS Servers, IPv6 DNS Servers, or Domain Name fields or click the Renew DHCP Lease button unless youβre instructed to do so by your ISP or network administrator.
Click Update to save your changes.
