PPPoE stands for Point-to-Point Protocol over Ethernet.
 
It relies on two widely accepted 
standards: PPP and Ethernet. It connects users through an Ethernet to the Internet with a 
common broadband medium, such as a single DSL line, wireless device or cable modem.
 
All 
the users over the Ethernet can share a common connection. And the PPPoA stands for 
Point-to-Point Protocol over ATM. PPPoA uses the PPP dial-up protocol with ATM as the 
transport.

PPPoE or PPPoA connection for accessing the Internet. Your service provider will provide 
you information about user name, password, and authentication mode.

for this router. The following page will be shown:
