Troubleshooting

This section offers solutions to common issues that may occur during the installation and operation of your ADSL Ethernet Modem.

1.Which protocols might I need to use with my ADSL Ethernet Modem?

•Refer to the documentation or manual provided by your ISP for details. The protocol required in your configuration depends on the equipment used by your DSL service provider. There are several possibilities:

a.Point-to-Point Protocol Over ATM (PPPoA) (RFC 2364) - PPP pro- vides session setup, user authentication (login), and encapsulation for upper-layer protocols such as IP (Internet Protocol). The use of PPP makes the modem appear as a dial modem to the operating system. Dial- Up Networking is used to establish a connection.

b.Bridged/Routed Ethernet/IP over ATM (RFC 1483) - This protocol makes the modem appear as a local area network (LAN) device to the operating system.

c.Point-to-Point Protocol Over Ethernet (PPPoE) (RFC 2516) - PPP provides session setup, user authentication (login), and encapsulation for upper-layer protocols such as IP (Internet Protocol). PPP makes the modem appear as a dial modem to the operating system. Dial-Up Networking is used to establish a connection. The protocol must be sup- ported by a PPPoE client, such as WinPoet or EnterNET 300 logon soft- ware, on the RFC 1483 driver.

2.The ADSL Ethernet Modem can achieve an ADSL connection, but cannot access the Internet.

•If network settings are assigned by the DHCP server, check whether the IP address and Gateway IP address have actually been assigned by the DHCP server.

•Try to ping the Gateway IP Address, then check the response from the Gateway.

•If this fails, contact your ISP for more information.
