Your system seems to have Intel PROSet Wireless combo adapter (WiFi + Bluetooth) as you mentioned earlier. I shared the web link in prior post that has the latest software package from Intel for this adapter.
You may try uninstalling the package(s) you have from "Control Panel\Programs\Programs and Features" Or Uninstall from Device manager for both Network and Bluetooth adapters (right click on device node and uninstall- make sure you check the box to delete driver files). Then reinstall the package that is on the Intel Web Link. Note that you have to download the package you need and save it off to local disk before you uninstall Network Adapter drivers.
Hope this will help you get back your IHV drivers.
