Hello Jake Lo, thank you for your great work on Dell laptops !
I am currently struggling to get Wifi working on my E5470 and E5570 (same wireless chip : DW1560). I get no wifi card recognized using your ACPI patched folder (Bluetooth works), and as soon as I leave the ACPI/patched folder empty, Wifi works perfectly. Only problem : I lose the ability to customize the screen Brightness (it remains quite dim, which is a bit of a pain). Also the laptop does not seem to go to sleep when I close the lid, but sleeps fine when I click "Suspend" in macOS.
I thought the solution would be to patch my DSDT/SSDT files by myself, but I encounter compiling errors.
Would you be so kind to check and see if you can patch my ACPI/origin/DSDT.aml and SSDT*.aml files ? That would be fantastic.
