finaly i find the answer :

in control panel -- administrative tools -- computer managment -- services and applications --services -- "wlan auto config"

most be on automatic mode and running.

when i boot my laptop with a live ubuntu dvd everything is ok and wifi works fine and wireless networks are being recognized. but in windows ...
and in device manager wireless card is enable and...

there is no "oem lenovo wifi manager" program on my laptop.
and as i said i was download wireless card driver from lenovo support center and install it twice and nothing happend !

i disabled automatic updates before this problem .
and Airplane mode is off.

i have a lenovo ideapad 310 laptop and When I press the right corner of the taskbar I see:
110490

As you see no wifi network is available and when I use "identify and repair network problems"...
