Question Inspiron 15 5000 Series WiFi not working after re-installing Windows 10

So I re-installed Windows 10 in my Dell Inspiron 15 5000 Series (5570) after I'm done re-installing is it does not show WiFi it only shows Airplane Mode, that's all that is showing. I've tried installing drivers from the dell drivers support entering my Service Tag and trying every single WiFi Driver that is shown, also I tried installing Intel 3165 and 7265 Wi-Fi Driver but It won't allow me saying "This installation is forbidden by system policy. Contact your system administrator" I've tried searching it up and trying every possible solution but it doesn't seem to work.

^ Also, I'm only using ethernet cable to download drivers and try single one of them
