8. The firmware upgrade failed, and/or the Diag LED is flashing. The upgrade
could have failed for a number of reasons. Follow these steps to upgrade
the firmware and/or make the Diag LED stop flashing:
A. If the firmware upgrade failed, use the TFTP program (it was downloaded
along with the firmware). Open the pdf that was downloaded along with the
firmware and TFTP program, and follow the pdf's instructions.
B. Set a static IP address on the PC. Use the following IP address settings for
the computer you are using:
IP Address: 192.168.1.50
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
C. Perform the upgrade using the TFTP program or the Adapter's web-based
utility through its Help tab.
9. My DSL service's PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can
disconnect the service after a period of inactivity, just like a normal phone dial-
up connection to the Internet. There is a setup option to "keep alive" the con-
nection. This may not always work, so you may need to re-establish connec-
tion periodically.
A. To connect to the Adapter, go to the web browser, and enter
http://192.168.1.1 or the IP address of the Adapter.
B. Enter the password, if asked. (The default password is admin.)
C. In the Setup tab, select the option Keep Alive, and set the Redial Period
option at 20 (seconds).
D. Click the Apply and Continue buttons.
E. Click the Status tab, and click the Connect button.
F. You may see the login status display as Connecting. Press the F5 key to
refresh the screen, until you see the login status display as Connected.
G. Click the Apply and Continue buttons to continue.
If the connection is lost again, follow steps E to G to re-establish connection.

10. The Diag LED stays lit continuously.
The Diag LED lights up when the device is first powered up. Meantime, the
system will boot up itself and check for proper operation. After finishing the
checking procedure, the LED turns off to show that the system is working fine.
If the LED remains lit after this time, the device is not working properly. Try to
flash the firmware by assigning a static IP address to the computer, and then
upgrade the firmware. Try using the following settings, IP Address:
192.168.1.50 and Subnet Mask: 255.255.255.0.
11. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
• Make sure that your workstation's IP settings are correct (IP Address,
Subnet Mask, Default Gateway, and DNS). Restart the computer that is
having a problem.
• If the PC is configured correctly, but still not working, check the Adapter.
Ensure that it is connected and ON and that the driver is installed cor-
rectly. Connect to it and check its settings. (If you cannot connect to it,
check the LAN and power connections.)
• If the Adapter is configured correctly, check your Internet connection
(DSL/cable modem, etc.) to see if it is working correctly. You can remove
the Adapter to verify a direct connection.
• Manually configure the TCP/IP with a DNS address provided by your
ISP.
• Make sure that your browser is set to connect directly and that any dial-
up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never
dial a connection. For Netscape Navigator, click Edit, Preferences,
Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.
12. The Full/Col LED keeps flickering continuously.
• Check the Category 5 Ethernet cable and its RJ-45 connectors.
• There may be interference with other network devices. Try removing
other PCs or network devices to see if the problem persists. Eliminate
each network device one at a time to determine the cause.
