wireless AW-CE123H not working in Catalina

[LyonLeBrun]

Here's the Save... output from IORegistryExplorer. Thanks.

IOReg looks good except no wifi loaded.

You have darwin 19.6.0, so I guess you're running Catalina 10.15.6. No need to install IO80211Family.kext (Mojave) to /L/E. Remove it, repair permissions and rebuild cache. Make sure you have vanilla IO80211Family.kext of Catalina in /S/L/E (untouched). 

If that still not working, try at OC picker, select 'Reset NVRam'. 

The AW-CE123H is the same as the DW1550 and it's working fine on my E7440.

That is my bad, I forgot to update the model description. Here's the updated Config but I don't think that would make a difference, the problem is elsewhere.

Thanks for the advice and updated config.plist. Wireless still doesn't work, but the symptoms have changed.

 

Now the Wi-Fi icon is a black-outlined fan shape. Selecting "Turn Wi-Fi On" causes it to go to grey fan for a few seconds before turn to a black-outline fan again.

 

System Preferences -> Network - Wi-Fi shows a "Turn Wi-Fi on" button, but that has no effect. I attach the latest IORegistryExplorer output.

 

Here's what I did:

• Removed IO80211Family.kext from /L/E
• Verified that both IO80211Family.kext and IO80211FamilyV2.kext (untouched) are present in /S/L/E
• Repaired permissions, rebuilt caches
• Restarted
• When the OC Picker came up, used Reset NVRAM
• Copied your newest config.pilst to /EFI/EFI/OC (Note: the only changes from your original OC EFI version seem to be s/Compatible/compatible/, s/14e4,43b1/pci14e4,43a0/, s/BCM4331/BCM4352/ in "model", and to move the "AirportBrcmFixup.kext" bundle path above the "AirportBrcmFixup.kext/Contents/Plugins/AirPortBrcm4360_Injector.kext". Is this correct?)
• Restarted - and now have the behavior described above

I agree the problem could be elsewhere - what other information can I provide? Many thanks.

Forgot to mention, you need to disable SIP. In order to do that you need to boot to the recovery mode just like a real Mac. Run

csrutil disable

reboot to Catalina, run

sudo kextcache -i /

reboot back to recovery mode, turn back on SIP

csrutil enable

reboot

[LyonLeBrun]

No change to the behavior (I still have the black outline icon. Choosing "Turn Wi-Fi On" causes it to go to grey fan, then the black outline again.) I used Utilities -> Terminal from Recovery mode to disable SIP (with csrutil disable), then booted back to Catalina disk and ran the kextcache command.

 

I ran three variations on the kextcache command, since the first didn't seem as if it worked right:

• sudo kextcache -u / (gave Warning: /AppleInternal/Library/Extensions: No such file or directory)
• sudo kextcache -Boot -U / (gave message that everything was up to date - I will note that earlier invocations also gave this same "up to date" result) and
• sudo kextcache -i / (appears to have worked without incident)

(I am hopeful that the second and third commands didn't cancel out the first...) Here's the output:

richb@Richs-MacBook-Pro github % sudo kextcache -u /     
kextcache -u /
Warning: /AppleInternal/Library/Extensions: No such file or directory

richb@Richs-MacBook-Pro github % sudo kextcache -Boot -U /
kextcache -Boot -U /
kext allow list already up-to-date for boot FDFD814E-85FB-47D0-9042-6CC5576BE60C

richb@Richs-MacBook-Pro github % sudo kextcache -i /
kextcache -i /
kextcache -arch x86_64 -local-root -all-loaded -kernel /System/Library/Kernels/kernel -prelinked-kernel /Library/Apple/System/Library/PrelinkedKernels/prelinkedkernel -volume-root / /Library/Extensions /AppleInternal/Library/Extensions /Library/Apple/System/Library/Extensions /System/Library/Extensions
KernelCache ID: E9A7E7FBE6144200232AC43CBC44FB07
richb@Richs-MacBook-Pro github % 

 

I then rebooted back to recovery mode, used csrutil enable, and then rebooted back to Catalina. That's where things stand with the black-outline Wi-Fi icon.

 

I'm still game to try other solutions/dig out other troubleshooting info. Thanks again.

Go to Network preferences. Click on the + sign on the bottom right.

In the Interface drop down arrow, do you see Wi-Fi as an option?

[LyonLeBrun]

Yes. See the Network Preferences movie on Youtube.

 

I was slightly surprised to see the OpenWrt5 SSID listed - this installation has never successfully been on Wi-Fi, yet that's one (of *two* SSIDs at my home...) Thanks.

 

[LyonLeBrun]

I should also note the my internal drive's top-level /EFI folder has a number of files seemingly created for each boot with a filename of opencore-yyyy-mm-dd-hhmmss.txt, with this data in them:

 

00:000 00:000 Dependency com.apple.iokit.IOHIDSystem fallback to com.apple.iokit.IOHIDFamily succeeded. Please fix your kext!
00:185 00:185 Dependency com.apple.iokit.IOHIDSystem fallback to com.apple.iokit.IOHIDFamily succeeded. Please fix your kext!

Ok, that's a good sign your wifi should be working, just not able to turn it on. 

Check your BIOS, do you have WWAN/WiGig/WLAN/Bluetooth Switch enable under Wireless?

On the right side of your laptop, there's a toggle switch. Make sure it's set to ON (not showing red).

 

The above error is easy to fix. Navigate to the VoodooPS2ControllerR6/contents/Plugins/

There are 2 kexts, open info.plist from both plugins and change com.apple.iokit.IOHIDSystem to com.apple.iokit.IOHIDFamily under OSBundleLibraries
