I updated my bios from 40cn22ww_64 to 40cn33ww_64. My wireless does not work properly. It is on FN and F5. It shows no networks. Diagnose says Problem found, There might be a problem with the driver for the wireless network connection adapter. The adapter is an Atheros AR9285 Wireless Network Adapter. The driver is version 126.96.36.199. I have tried to find another driver and have not been able to. I have uninstalled the adapter and reinstalled it. Any ideas. Windows 7 update will not work. It goes to 45% and fails! Please help!!!

Welcome to Lenovo Community Forums!
I’m sorry to hear that the Wireless is not working as expected after installing BIOS update in your G470 Laptop, below is the link to download next version of the wireless Atheros 188.8.131.526 wireless driver:
Do post us back if the issue still persists.

I have tried the updated driver. Does not work. No wireless networks appear at all. I tried to install an external Cisco Valet adapter. It won't install. Say's it has to be managed by windows and some other program is managing my wireless. I can not find out how to make windows in control. I have tried to uninstall any programs that appear they might be in control. Don't know how to see or do this in Windows 7 Home Premium! Any help will be appreciated.

I’m sorry to hear that the issue persists even after updating the Wireless Network drivers in the computer, I suggest you to attach the snapshot of the error message that is popping up while you try to use the Cisco Valet adapter and please perform “System Restore” in the computer and check the issue. Below is the link for the steps to perform “System Restore”:
Hope to hear back soon
