Chapter 8 Troubleshooting

Reloading the Access Point Image

If your access point has a firmware failure, you must reload the complete access point image file using

the Web browser interface or by pressing and holding the MODE button for about 20 to 30 seconds. You

can use the browser interface if the access point firmware is still fully operational and you want to

upgrade the firmware image. However, you can use the MODE button when the access point has a

corrupt firmware image.

Using the MODE button

You can use the MODE button on the access point to reload the access point image file from an active

Trivial File Transfer Protocol (TFTP) server on your network or on a PC connected to the access point

Ethernet port.

Note If your access point experiences a firmware failure or a corrupt firmware image, indicated by three red

LEDs, you must reload the image from a connected TFTP server.

Note This process resets all configuration settings to factory defaults, including passwords, WEP keys, the

access point IP address, and SSIDs.

Follow the steps below to reload the access point image file:

Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.

Step 2 Place a copy of the desired access point image file (such as c1100-k9w7-tar.122-13.JA.tar) into the TFTP

server folder on your PC. For additional information, refer to the “Obtaining the Access Point Image

File” and “Obtaining the TFTP Server Software” sections.

Step 3 Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default.

Step 4 Activate the TFTP server.

Step 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 6 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the

access point.

Step 7 Press and hold the MODE button while you reconnect power to the access point.

Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the

MODE button.

Step 9 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED

blinking green.

Step 10 After the access point reboots, you must reconfigure the access point by using the Web interface, the

Telnet interface, or IOS commands.
