Appendix A: Troubleshooting
Common Problems and Solutions

EtherFast Cable/DSL VPN Router with 4-Port 10/100 Switch

12. 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

. Follow these steps:

A. Go to the Linksys website at

http://www.linksys.com

and download the latest firmware.

To upgrade the firmware, follow the steps in the Upgrade section found in “Chapter 6: Using the Router’s
Web-based Utility” 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. 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 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 program or the Router’s Web-based Utility through Firmware

Upgrade screen of the Administration tab.

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.

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.
