Try reverting the AP to IOS, using the c1100-k9w7-tar.default file name method as mentioned in the link.

Read the section ;

"Using the MODE Button to Return the Access Point to Autonomous Mode " in the link in your original post.

To summarise;

Step one: Change your workstation address to

Step two: Rename IOS image (tar file) to c1100-k9w7-tar.default

Step three: setup tftp server

Step four: Connect AP and workstation to switch or interconnect with a crossover cable.

Step five: Turn on AP while holding down mode button for +- 20 seconds (Radio led turns red) then release mode button

Step 6: Wait until the access point reboots, as indicated by all led's turning green followed by the Status led blinking green

Try a crossover cable if you cannot connect to the AP with your PC. It's an 1100, right? 1100s do not support auto-MDIX.

Do you mean CAT5 cable? Yes. I tried it but it didn't work. I tried Ping then no response from AP. I need my ap back to Cisco System for fix it.

I'd RECOMMENDED IOS Software NEED to add for putting wrong IOS Software then it will tell you for IOS failure, reboot for get old IOS Software back without getting problem.

And I tried everything. I dont have any tool (Cisco controller, many thing). I like Cisco System because it best network technology.

BUT it LOT money than all.
