Sorry I thoght that you did see the system report that i included, and you did shown me that the other card that i have (AR5BXB63) is no longer supported so i drop the idea, yes i do have the original card that is wi fi and bluetooth combo card installed same one on your Sierra Build, i don't know how i can tell you exactly how got here only thing i can pass is copy of EFI and System library extensions folder, i am not english speaking native and sometimes i may miss understand something like i did when you made the question that i thought that you ware just letting me know about solutions out side the internal card. Thank's to all info you provided only the original wifi is missing for the over all success of this project, and yes i am using a dongle to access wi-fi but you have been building this system with all working components that in my view only you have the knowledge the help me finish successfully with all working order, i know that this is very very very hard but it's so close, i don't know i read somewhere that sometimes Kexts may conflict, but i don't think that is the case here, i don't know thats why i asked help to someone that really understands how the hole thing works together, it's ok i am really happy for all what is done and if this is the way that it can best be so it is i don't see myself without a tutor reach the over all success all i have to do is to thank you very much for this i would not be able to do it on my own, THANK YOU. and sorry if i miss understand something any way this is almost success...
