How to Renew a DHCP License on a Mac

Renewing your DHCP lease is a simple troubleshooting method to fix issues with connecting to the Internet. DHCP, which stands for Dynamic Host Configuration Protocol, refers to the automatic configuration for your IP address, which your Mac automatically renews on a regular basis. If you can no longer connect to the Internet or if your Mac is mysteriously self-assigning an IP address -- these begin with prefixes such as 169 -- manually renewing your DHCP lease can often fix these problems.

Instructions

1. Click the "System Preferences" icon in your Dock. Alternatively, you can open System Preferences via your "Applications" folder or the "Apple" menu.

2. Click the "Network" tab under the "Internet & Network" heading. System Preferences should automatically select your primary Internet connection. If it does not, click your primary Internet connection in the left column.

3. Click the "Advanced" button and then click the "TCP/IP" tab.

4. Click the "Renew DHCP Lease" button. Click the "OK" button after renewing your lease to exit the "Advanced" window and close your System Preferences.
