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 is used for most of DSL modem users. All local users can share one
PPPoE or PPPoA connection for accessing the Internet. Your service provider will provide
you information about user name, password, and authentication mode.
If your ISP provides you the PPPoE or PPPoA connection, please select PPPoE or PPPoA
