WiFi Network Adapter is missing under Windows 10

Hi folks,

I am using IMAC. I just installed windows 10 on external drive with bootcamp and setup windows support from usb flash. Everything goes well but I cannot see my WiFi network adapter under windows 10 and WiFi setting is missing too. May be it looks like windows does not recognise network adapter. So How do I fix it? Any Idea?

Could you please help me with this issue?

I am waiting for your response

Thanks in advance
