This article explains how to set up Point to Point Protocol over Ethernet (PPPoE) Internet access, how the protocol works, and potential issues. Specific instructions for setting up PPPoE vary by manufacturer, with Belkin, Linksys, Netgear, and TP-LINK taking varying approaches.
How to Set Up a PPPOE Internet Connection on Your Router
Select PPPoE as the connection type in your router's Settings or Internet menu.
Enter the required parameters in the fields provided. You will need to know the PPPoE username, password, and (sometimes) the maximum transmission unit size.
PPPoE Internet service providers assign each of their subscribers a unique PPPoE username and password. Providers use this network protocol to manage IP address assignments and track each customer's data usage.
