Can't find a Wireless Network Adapter on my Lenovo G 580

When I look at the Network Adapters in the "Device Manager", I only see the following:

Atheros AR8162/8166/8168 PCI-E Fast Ethernet Controller (NDIS 6.20)


I have downloaded both the LAN as well as WLAN drivers that have been advocated on these forums. However, I can't seem to get WLAN connectivity on my laptop. What am I missing ?


I have also tried the BIOS settings to first disable and then enable the Wireless. But that doesn't seems to work either. 


From the "Network and Sharing Center", when I clck on the "Set up a new connection or network", I get an option like "Broadband(PPPoE)". And nothing else. Should I not expect a Wireless option here ?

hi riteshgoel,


Welcome to Lenovo Community Forums!


There might be three possible problem.


Driver Issue

  -If it is a driver problem then you should have a yellow icon in Device Manager saying maybe "Network Controller" or "Unknown Device"


BIOS Wireless LAN is Disabled "Which I think you alreay tried"

  - You can check your BIOS settings, as it has an option to disable the WIFI hardware,

   Go to BIOS by tapping F2 or FN+F2 once you power on the system.
    Once inside BIOS Go to the "Configuration" tab
    Look for "Wireless Lan" and make sure it is enabled.
Then hit F10 on your keyboard to save and exit BIOS.
If those two are not the issue
     - Given that it is not showing any Wireless device or a Yellow icon/Unknown device Under Device Manager " Let me know if there's any".
     - Under BIOS Wireless is Enabled
Then this is most probably a Hardware Problem and should be brought up with Lenovo Technical Support.
Best Regards
Solid Cruver

This is because you could not install the driver for Wi-Fi, for reason still unknown.

As soon as you get it installed, Wi-Fi shoud work.
