Manage Network Connection in Task Bar - Wireless TAB "DISABLE" state for opensuse 12.3

I am totally new.
Installed opensuse 12.3 on my Dell inpiron 10 inch laptop, that now has dual boot.

I gets connected to internet well via - Network Cable.
But i use my home Wireless, i cannot.

On bottom, taskbar, i click on Configure- KDE Control Module -> Network Connections
I see Wired, VPN and DSL only enabled.
"Wireless" TAB is disabled.

I connect to windows and i see wireless is enabled and it connects fine.
I read all forum post and tried few stuff nothing worked.

Here is the output of thing i ran:
