Testing a Cisco Aironet 1250 series I needed to enable WPA, so these are the steps I did it via web GUI:
In SECURITY > Encryption Manager
Set Cipher: TKIP
Set Encryption Keys clean
in SECURITY > SSID Manager > Client Authenticated Key Management
Set Key Management: Mandatory
Enable WPA with you preferred version, and create your WPA Pre-shared Key as you want
And that’s all..
