uhm no WWAN here, WLAN is on, but not associated to any AP, and i have 
no idea how to use bluetooth. Some input from your side would be help full.

Switching the hardware switch off did not change this, also ifconfig 
still shows the wireless interface. Not sure if that info helps.

Uh, what?

While the hardware button is off, i can switch it to enabled, but since 
i dont know how to use bluetooth im notesure if its really on or not?

Not sure here either.
