About Mac will ask the DHCP server (usually a Wi-Fi router) for a new IP address, and use the same address or a new address to connect, depending on the details provided by the router. Let's take a look at the specific steps with the editor!
1. To find these settings, click the "Apple" icon in the upper right corner of the menu bar, and then select "System Preferences".
2. Click "Network" in the "System Preferences" window.
3. Select the appropriate network, and then click the "Advanced" button. This applies to wired (Ethernet) and wireless (Wi-Fi) connections.
4. The next screen should default to the Wi-Fi tab, select "TCP/IP" instead.
5. Click the "Renew DHCP License" button, and then click "OK" after the renewal is complete. Click this button to instruct the Mac to obtain new routing information from the DHCP server.
Resetting this setting can improve the connectivity of your Mac, especially if you have recently changed the router settings.
The above is what the editor shared for you today, I hope it will be helpful to you.
