Fn+F2 does not turn on or off the wireless network. the light indication of Wi-Fi also doesnt turn on. it is off constantly. i think it contains: Dell Wireless 1390 or 1395 WLAN MiniCard. plx help asap! waiting.

1st you have to see if it's used by the system
go to settings >> software & updates >> additional driver
and check to use the wireless adapter by system if it's not used
if it's not working reply me i'll help
go to Software Sources in System settings (think its called software and updates now) the last tab is addition drivers , select that and active the Broadcom driver
