I have a Cisco AIR-AP1131AG-A-K9 wireless access point. This AP is an autonomous (stand alone) AP not used with a wireless controller. I used Cisco's upgrade tool & the correct image to upgrade the AP to LWAPP (so it could be used with a Cisco wireless controller). Now my controller does not recognize the AP I upgraded. So...now I want to downgrade or flash the Cisco AIR-AP1131AG-A-K9 access point via hyperterminal & a console cable. Can anyone tell me what commands to type in to reset the whole image/AP back to factory default? It does get an IP address from my DHCP server but I can't telnet into it. I basically just want to reset this AP back to factory default with the non-lwapp image. Is this possible?? Any help will be appreciated.
Yes, you can absolutely revert back to autonomous mode. What exactly do you mean by saying that the controller doesn't recognize the AP? Do you want to troubleshoot that first, or do you just want to revert back?
I found the following section in this document: http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp161272. I hope it helps!
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1. The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 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. On the PC where the TFTP server is located, perform these steps:
a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View > Show hidden files and folders.
Step 4. Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
Step 5. Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 6. Disconnect power from the access point.
Step 7. Press and hold MODE 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 then release.
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, reconfigure it using the GUI or the CLI.
