Hi,

I am facing the problem with my Lenovo G570 purchased before 4 month.

Wireless on my G570 shows like my wireless card is not being found. And it will fix some time automatically. But Again facing same problem. I checked Fn+IF it shows both (Bluetooth and Wireless network card) status as ON. But still in Network and Sharing center screen only Bluetooth device is shown. I checked Driver and re-Install it but nothing happen. Wireless network card is still Not Found.

I am attaching the picture of allscreen.

Network and Sharing center shows as no wireless card

Hello ravirajcm and welcome to community,

Please make sure the wireless switch is on which is available in front view of the laptop.

Update the BIOS and install the updated wireless lan driver

For Windows 7 32bit

For Windows 7 64bit

Best Regards,

Tanuj
