WAP Downgrade from LWAPP to Autonomous AP and to bind to another WLC

If the Cisco 1230 LWAPP was a member another wireless network the certificate must be removed and regenerated to bind to another network controller.

Follow these steps to revert from lightweight mode to autonomous mode by loading a Cisco IOS release using a TFTP server:

Step 1 The PC on which your TFTP server software runs 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 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 the default image name - it will c1200-k9w7-tar.default for an 1200 series AP c1130-k9w7-tar.default for an 1130 series AP

Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 5 Disconnect 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. For the 1130 APs, hold the button until the console indicates that the button is pressed (the R LED will be solid red): button is pressed, wait for button to be released... button pressed for 25 seconds process_config_recovery:      set IP address and config to default 10.0.0.1
process_config_recovery: image recovery image_recovery: Download default IOS tar image tftp://255.255.255.255/c1130-k9w7-tar.default
Once it starts uploading, the E & R LEDs will both be blinking (1130 AP). Once you release the button, you should see the console extracting files from the tarball on the TFTP server.

Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green. You can also observe the console to see when it reboots - this is a better bet, as some APs behave differently than others in terms of LED operation.

Step 9 After the access point reboots, reconfigure the access point using the GUI or the CLI

Now plug in a live network ethernet to join to the WLC, CAPWAP discovery should find the device and add to the system. It will auto generate a new certificate (SSC)
