[solved] BCM94352Z Lenovo Yoga 2 13 (not pro) a WLAN problem

luftoder said:

since few days i'm struggling with the card. I need help. I read many topics related to the card on this web site, but unfortunately nothing helps. I cannot find the reason.

Main info:
- I use Clover
- OS: 10.12 Sierra
- i have dropped kexts:
-----> BrcmFirmwareData.kext
-----> BrcmPatchRAM2.kext
-----> FakePCIID.kext
-----> FakePCIID_Broadcom_WiFi.kext
----------> into EFI/CLOVER/kexts/10.12, EFI/CLOVER/kexts/Other and S/L/E
- after that Bluetooth is working, but WIFI is not recognized at all
- I have Windows and Ubuntu on this Laptop and BCM94352Z is working there perfectly.

Info about Yoga 2 13 (in short):
- Intel i3-4010U
- HD Graphics 4400
- Realtek HD Audio (?)
- Mainboard: Intel lynx Point-LP
- BCM94352Z

Report about Hardware and IOReg are attached

thank you for the reply RehabMan,
but I had no luck with the darkvoid's patch (link to patch: http://www.insanelymac.com/forum/topic/312759-fix-macos-sierra-dp1-bcm94532z-wifi/ ).

I tried:

1) PATCH 1: darkvoid's patch (copy/paste the code into config.plist)

<dict>
<key>Comment</key>
<string>AirPortBrcm4360 - fcvo</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>gflSqgAAdSk=</data>
<key>Name</key>
<string>AirPortBrcm4360</string>
<key>Replace</key>
<data>gflSqgAAZpA=</data>
</dict>

2) PATCH 2: kext force load (add the \System\Library\Extensions\IO80211Family.kext\Contents\PlugIns\AirPortBrcm4360.kext into config.plist via Clover Configurator)

<key>ForceKextsToLoad</key>
<array>
<string>\System\Library\Extensions\IO80211Family.kext\Contents\PlugIns\AirPortBrcm4360.kext</string>
</array>

3) PATCH 3 and 4: In the ACPI patches menu select "AddDTGP" and "FixAirport"
with choosed "FixAirport" patch i have "Black Screen" after Clover's Boot Menu, so I can boot only with "AddDTGP"

4) I have tried to add Device FakeID into the wifi box: 0x43BA14E4 - no result, just as before, WIFI shows any signs of life

I am glad for any further help

No need for a FakeID or FixAirport.

I tried without FakeID and FixAirport. I do not understand why Sierra cannot enable WIFI. What could be done else and where i must dig to solve this issue? hmm...

Thank you very much RehabMan!

WiFi is working !!!
It was my fault. I have placed the patch-code into wrong section of config.plist (it was in section "Patches").

Now I'am happy (for a while)
