Windows 10 bootcamp retina early 2015 wifi not working

Hey everyone, I have driven myself mad. I originally installed the upgrade to windows 10 a few months back. Then I rolled it back and waited for the new drivers. I have upgraded to the new CAPITAN and the bootcamp 6 drivers but nothing has worked. I installed with .exe, I unistalled the drivers and scanned for changes, I have installed the legacy and windows 7 manually, and I tried to use the MSI as well. Nothing has worked. Any help would be great, It says in the history that the device PCI requires futher installation. Please let me know
