Can someone provide the correct way to 'downgrade' an air-lap1242ag to an autonomous AP?
1st Configure your PC with one of this IP address 10.0.0.2 ==> 10.0.0.30 and use direct ethernet connection with your AP
2nd Download the IOS file from Cisco
3rd Rename the file with one of this name:
c1200-k9w7-tar.default for a 1200 series access point
c1130-k9w7-tar.default for an 1130 series access point
c1140-k9w7-tar.default for an 1140 series access point
c1240-k9w7-tar.default for a 1240 series access point
c1250-k9w7-tar.default for a 1250 series access point.
4th Use you favourite tftp server program and put the renamed file on the correct folder.
5th Unplug the power on the AP and press the MODE button, hold...
6th Plug the power and wait about 20-30 sec with the MODE button pressed, release the button
(You could see the in the tftp Server log your AP going and also in the terminal)
That's all, wait for the AP finish the downloading process and reboot
I hope this helps
