Lenovo G50-45 Wireless Network Adapter not working after Windows 10 upgrade

I just installed Windows 10 onto my laptop from Windows 8.1. All is well except that the wireless network adapter isn't working.


The adapter is a Broadcom 802.11ac Network Adapter.

The device status states:

"This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful."


Upon opening the Events tab in device manager, I have three boxes stating the same thing:
"Device install required."

Each of them state the same thing in the information box under:

"Device PCI\VEN_14E4&DEV_43AE&SUBSYS_062217AA&REV_02\000008FFFF00300E00 requires further installation."

I also found a box stating:

"Device PCI\VEN_14E4&DEV_43AE&SUBSYS_062217AA&REV_02\000008FFFF00300E00 was not migrated due to partial or ambiguous match.

Last Device Instance Id: SW\{EEAB7790-C514-11D1-B42B-00805FC1270E}\ASYNCMAC
Class Guid: {4D36E972-E325-11CE-BFC1-08002BE10318}
Location Path:
Migration Rank: 0xF000FFFFFFFFF102
Present: false
Status: 0xC0000719"


I have tried uninstalling the drivers and reinstalling, I've tried resetting network settings, I've tried updating both from the computer and off of the Lenovo website. Nothing is working and I don't know what to do. I will note that the ethernet port still works, but I cannot get wifi to work. Any help would be seriously appreciated.

Try setting BIOS defaults and rebooting the notebook. Also - try installing drivers for Windows 8.1 using compatibility mode, as this removes much of the Windows 10 upgrade issues.
