13. 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; refer to "Problem #1, I need to set a stat-
ic IP address." 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 Router's web-based
utility through its Help tab.
14. I am using PPPoE with my DSL service, but it is always disconnecting.
PPPoE is not a dedicated or always-on connection. The DSL ISP can discon-
nect the service after a period of inactivity, just like a normal phone dial-up
connection to the Internet. Using the setup option "keep alive" will help keep
the connection. This may not always work, so you may need to re-establish the
connection periodically.
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1 or the IP address of the Router.
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 button, and then click the Continue button.
E. Click the Status tab, and then 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 button and click the Continue button to continue.
If the connection is lost again, follow steps E to G to re-establish the connec-
tion.

15. I can't access my email, web, or VPN, or I am getting corrupted data from the
Internet.
The Maximum Transmission Unit (MTU) setting may need to be adjusted. By
default, the MTU is set at 1500. For most DSL users, it is strongly recom-
mended to use MTU 1492. If you are having some difficulties, perform the fol-
lowing steps:
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1 or the IP address of the Router.
B. Enter the password, if asked. (The default password is admin.)
C. Click the Advanced => Filter tab.
D. Look for the MTU option, and select Enable. In the Size field, enter 1492.
E. Click the Apply button and click the Continue button to continue.
If your difficulties continue, change the Size to different values. Try one value
at a time, in this order, until your problem is solved:
1462
1400
1362
1300
16. I need to use port triggering.
Port triggering looks at the outgoing port services that are used and will trigger
the Router to open the port that the Internet application uses. Follow these
steps:
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1 or the IP address of the Router.
B. Enter the password, if asked. (The default password is admin.)
C. Click the Advanced => Forwarding tab, and click the Port Trigger button.
D. Enter any name you want to use for the Application Name.
E. Enter the Triggered Port Range. Check with your Internet application
provider for more information on which outgoing port services it is using.
F. Enter the Incoming Port Range. Check with your Internet Application
provider for more information on which incoming port services are
required by the Internet application.
