[ngoctraiden9x]

I've just bought a Lenovo Ideapad Z470 - Win 7 ultimate 32 bit
Although I installed full driver, I couldn't connect to Wifi
I used : troubleshoot problem ---> still not working

wireless light not on
My brother did something ( not install/uninstall anythings), Wireless worked
But when I restart, it's not working
Help me, please

Did you install Power management? If not, please, install it first then press Fn +F5 to activate the wireless

Can you post a screenshot of device manager with network adapters expanded and then expand your wireless adapter link and post please.

If you expand your wireless adapter does it display This device is working properly?
