I tried to downgrade a 1242 LAP to Autonomous through a WLC using cisco's brief instructions:
Step 1 Log into the CLI on the controller to which the access point is associated.
Step 2 Enter this command:
config ap tftp-downgrade tftp-server-ip-address filename access-point-name
Seems easy enough, i copied the IOS file (c1240-k9w7-tar.123-7.JA5.tar) to my TFTP root. Then i ran the command mentioned above from the CLI of the WLC. The WLC takes the command but nothing happens, if i hold down mode and reboot the AP it retains its previous settings? Any ideas?
