9. On the PPP Username and Password page you will need the following information:
 PPP Username: Your account from ISP to access Internet.
 PPP Password: The password assigned by your ISP.
Note: If you set the username/password to default/default, the modem will redirect the
user to a web page within the modem to change their password when they first log on.
 PPPoE Service Name: Server name of network ISP. No need to set this.
 Authentication Method: Authentication mode of network ISP. Default is AUTO.
 MTU: the Maximum transmission unit (MTU) value may be set for your needs. Higher
MTU can provide for a more efficient link because each packet will carry more data while
the overhead in the packet such as header information does not get larger with the size
of the packet. So the bulk throughput on the link will go up. Generally a large packet size
can occupy the time on the link, so the higher MTU can increase lag time and minimum
latency which is not appropriate for all applications.
MTU size can be 576-1492.
 Enable KeepAlive:
• KeepAlive Time: The interval in which the PPPoE client will send out keep alive
message to the PPPoE server to keep the PPPoE session up.
• KeepAlive Max Fail: The maximum number of retries the gateway will attempt if the
PPP client encounters an error. For example if the number is 1 the gateway will only
retry once.
 Enable NAT: Enables Network Address Translation. See NAT on page 81.
 Enable FireWall: Enables Firewall. See Firewall on page 85.
 PPP Dial Up Delay Seconds: The number of seconds the gateway will pause before
