Chapter 5 Troubleshooting Autonomous Access Points

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.
If your access point experiences a firmware failure or a corrupt firmware image, indicated by three red
Note
LEDs, you must reload the image from a connected TFTP server.
This process resets all configuration settings to factory defaults, including passwords, WEP keys, the
Note
access point IP address, and SSIDs.
Follow these steps to reload the access point image file:
The PC you intend to use must be configured with a static IP address in the same subnet as the access

point.
Place a copy of the desired access point image file (such as c1100-k9w7-tar.123-8.JA.tar) into the TFTP
Step 2
server folder on your PC. For additional information, refer to the
File"
Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default.
Step 3
Activate the TFTP server.
Step 4
Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5
Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the
Step 6
access point.
Press and hold the MODE button while you reconnect power to the access point.
Step 7
Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the
Step 8
MODE button.
Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED
Step 9
blinking green.
After the access point reboots, you must reconfigure the access point by using the Web interface, the
Step 10
Telnet interface, or Cisco IOS commands.
