Appendix A: Troubleshooting
Common Problems and Solutions
10/100 4-Port VPN Router
A. Go to the Linksys website at http://www.linksys.com and download the latest firmware, or use the
Web-based Utility to be automatically redirected to the download webpage. Go to System Management -
Firmware Upgrade, and click the Firmware Download from Linksys Web Site button. Select the Router
from the pull-down menu and choose the firmware from the options.
B. Extract the firmware file on your computer.
C. To upgrade the firmware, follow the steps in the Upgrade section found in “Chapter 6: Set Up and
Configure the Router” or “Appendix B: Upgrading Firmware.”
13. The firmware upgrade failed.
The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware:
A. Use the Linksys TFTD program to upgrade the firmware. Go to the Linksys website at http://
www.linksys.com and download the lthe TFTP program, which will be listed with the firmware.
B. Set a static IP address on the PC; refer to “Problem #1, I need to set a static 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 utility.
If the firmware upgrade failed, the Router will still work using its current firmware.
If you want to use a backup firmware version, go to System Management => Restart. Select Backup
Firmware Version. Click the Restart Router button to restart the Router.
14. 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.
