2.2.2 PPPoE/PPPoA

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

for this router. The following page will be shown:
