Hi,

I want to use kwifimanager in KDE 3.3 on my Fedora core 2 notebook.
After I configurate wireless setting and saved. I click activate
Configuration. I recevie following message from console.


Error for wireless request "Set Encode" (8B2A) :
invalid argument "key"

I find the essid is set but Encryption key setting is still off.

Anyone has solution?
