Connect your Mac to the internet using PPPoE
If you use a DSL or cable modem to connect to the internet, and your internet service provider (ISP) uses Point-to-Point Protocol over Ethernet (PPPoE), you need to create a new network service, and enter the information you received from your ISP.
Before you begin
