Boot up the AP and follow these directions, since you are having issues upgrading using the mode button... if this fails, then download the IOS image and rename the file again.

Ah... my bad... well try to use 3CDeamon TFTP and set your IP Address to  If you still have an issue, then download the IOS image again and rename it... Cisco IOS release 12.3(7)JA or earlier.  Try a different laptop or machine also.

%Error opening  M|h¦` è (connection timed out)

Sounds like your TFTP server is not pointing to the location/folder of your IOS.
