XPS 13 (2015 model) - WiFi Problems

Hello,

I can't get the WiFi from the XPS 13 to work in Sierra.
I installed the FakePCIID.kext and the FakePCIID_Broadcom_WiFi.kext from RehabMan but it's still not detected.

I verified that my WiFi module Device ID is 14e4:43b1 under ubuntu.
Did I missed something?

PS: I added the info.plist IO8022Family.kext/Contents/Plugins/AirPortBrcm4360.kext and applied the patch to the binary.

Kind regards
