13. I need to upgrade the firmware.
In order to upgrade the firmware with the latest features, you need to go to the Linksys website and download
the latest firmware at www.linksys.com/international. Follow these steps:
A. Go to the Linksys website at http://www.linksys.com/international and download the latest firmware.
B. To upgrade the firmware, follow the steps in the Upgrade section found in “Chapter 5: Configuring the
Router” or “Appendix B: Upgrading Firmware.”
14. The firmware upgrade failed.
The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware:
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 #2, I need to set a static IP address on a 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 Router’s Web-based Utility through its Administration
=> Firmware Upgrade tab.
15. 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 connection. This may not always work, so you may need to re-establish 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. On the Basic Setup tab, select the option Keep Alive, and set the Redial Period option at 20 (seconds).
D. Click the Save Settings button.
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.
If the connection is lost again, follow steps E and F to re-establish connection.
