How to enable WPA with Pre-shared Key on Cisco Aironet 1200 Series Access Point

1. switch form VxWorks to IOS
   1. Read the guide form Cisco
   2. in the readme they say you have to downgrade to VxWorks 12.03T. I was on the latest 12.05 and did not had an old image, but it works.
   3. you need AP1200-Cisco-IOS-Upgrade-Image-v3.img (if you did not want to save the old config)
   4. maybe you can update IOS to the latest version (in my case c1200-k9w7-tar.123-8.JEE.tar). I could only upgrade via tftp not http!
2. Default login is Cisco and password is Cisco
3. Security > SSID Manager
   1. check Open Authentication: NO ADDITION
   2. Client Authenticated Key Management > Key Management : Mandatory
   3. check WPA
   4. fill in WPA Pre-shared Key: 1234567890hsdkfh
