I have made an IOS upgrade to an aironet 1100 AP, but we had a power loss and now the ap is not starting. i can't access it nor by the old ip i have linked an ip by hand with arp -s, but i can't access it. how can I revert to the old IOS or how can i write a new ios to it? i have tried to push the mode button for about 30 seconds and the middle led went red, i have released the mode button and the upper led (green) and the middle led (red) started th flicker for about 30 seconds and after that it get on booting and restarting and so on. Thank you very much.

Hi Gorea,


Have a look at the method outlined below:


Using the MODE button


You can use the MODE button on 1100 and 1200 series access points 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 LED indicators, 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 these steps 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 Make sure that the PC contains the access point image file (such as c1100-k9w7-tar.122-15.JA.tar for an 1100 series access point or c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.


Step 3 Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default for an 1100 series access point or c1200-k9w7-tar.default for a 1200 series access point.


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 access point.


Step 6 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 MODE button.


Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.


Step 9 After the access point reboots, you must reconfigure the access point by using the Web-browser interface or the CLI.
