Hi everyone,

 

I just purchase several All-in-One C440-5731 desktop.

Then I installed Windows 7 Professional into them.

 

Thre driver disc that included in package is for Windows 8, so i download all the driver from here:
http://support.lenovo.com/en_ID/downloads/default.page?

All the driver is working, but only ONE that dont working. Wireless LAN driver.
I've tried Athorus driver and Realtek driver, but both of them not working. In device manage the device driver still error, i've try anothe PC and the problem still the same.

 

Please help me, is there any idea how to make it work.

hi khan2000,

 

Welcome to Lenovo Community Forums!

 

Can you post here the Hardware Id of the Wireless Device

     - In device manager Wifi device should show like Network controller with a yellow Icon.

                -Right-click on it and choose properties.

                -Click on the details tab on top

                -Change the property Value, change it to Hardware ID

                -then paste back here what's on the Value

Link to sample photo

 

This will help us the Name of the WIFI and will guide us on downloading the right driver

 

Solid Cruver

Thanks,

Re: All-in-One C440-5731 Wireless LAN error on Windows 7

hi khan2000,

 

This seems to be a Broadcom Device,

 

You can try installing this

Broadcom BCM4312 and BCM4313 Wireless LAN Driver
11002479.exe
39.7MB

 

See if this works.

 

Hope this helps

Cheers!

Yes, the driver has been successfully installed.
Broadcomm is the Wireless LAN for this C440.

Lenovo support team should update information into download section.

 

Thank you very much.

Welcome to the Lenovo Community calypso116 !

 

From the PCI numbers you have listed you will need to install the Atheros wifi driver for your model.  In checking the download page for the C440 I see there is a "Athorus" wifi driver available.  I suspect it is a spelling error and its really the Atheros driver you need.
