Yesterday I took the plunge and did a clean install of Monterey on my MacPro 5.1.

Everything went well and to my surprise both the USB3 cards and a flashed RX580 worked great from the start.

I'm also surprised to see that bluetooth through a cheap WTXUP BCM94360 still works in Monterey. However, WiFi through the same card does not.

WiFi (and Bluetooth) still work fine on Mojave. But I never removed the original Airport card from the computer, I just disconnected the antenna and power cable from the Bluetooth card.

Is there any hope that wifi can get to work in Monterey with this card? Apparently it is similar to the simpler Fenvi card.

Can you attach a backup of the ioregistry?

Thanks for replying.
Let me know if this is what you need.

Use OCLP to install the old WIFI driver Kexts.

I have an old 2010 5.1 with the original Airport card and BT 2.1 card.

Upon installation the Airport did not work. I went back into the OCLP app and clicked "Post Install Root Patch"

The software automatically installed the missing drivers and airport worked upon reboot.

Thanks for the advise.

Before installing Monterey, I removed the 3rd party BT/WiFi card because I read that WiFi and BT may work.

When I noticed that WiFi and BT didn't work I tried to do the Post Install Root Patch, but there was not anything available to be installed.

I then re-connected the card and noticed that BT worked fine.

Of course I can remove the 3rd party BT/WiFi card or the Airport card, re-connect the BT 2.1 card and re-install Monterey, but it's a bit overkill if a manual kext mod can solve the problem. What do you think? I mean... are there any kexts that could be added/removed manually?

I would reconnect the original apple airport and BT cards.

Then run the OCLP kext patch. to see that you have working wifi and BT.

After that you can try to get that Chinese PCIe card to work.

I never removed the Airport card. Followed you suggestion and removed the Chinese card and reconnected the BT card, restarted the computer ant voila!, the Post Install Root Patch was available.

But after running the patch and rebooting a few times, wifi and bluetooth still do not work.
WiFi seems to be available, but no networks are shown and can't connect manually either.

When removing the original BT antenna cable to put the Chinese card back, the tiny connector at the board got broken/unsoldered. I'll try to fix it later. If I am successful will probably try to do a complete reinstall of Monterey.

Just a brief update. After five or six restarts all nearby WiFi networks are shown at the top menu. However, I cant't connect to any, not even to my own Airport Express WiFi which is located 5 feet away from the Mac.

That means that the wifi in use is the original one where you disconnected the antenna cables. Without them the wifi will not connect to anything. Why don't you disconnect the original card to avoid confusion?
I can see 2 cards in the ioregistry, but the FENVI wifi is not attached properly and does not appear as an ARPT device: And here is the original card properly registered, but without antennas: As you can see the devices RP03, RP04, RP05 and RP06 are all occupied by the 2 ethernet ports, the firewire port and the original wifi and there is no more RP0X devices available to attach. So, you need to free some resources. Remove the original card and make a back up from the registry.

@zterm you can try this SSDT without disconnecting the original one.

I am lost.
I have never disconnected any antenna cables from the original WiFi card nor I have ever removed it from the machine. Actually, it works fine in Mojave. The other Chinese card works fine in Mojave as well.

Please forgive my ignorance. What should I do to try the SSDT you kindly attached?

Now I am lost. You said in the first post that you disconnected the antennas? How many antennas are disconnected now? It is a combo card and there are 3 antennas. The pictures you attached are for the original card in Monterey and Mojave. As I said the FENVI does not appear in the ioregistry as an ARPT device and it never worked ( see my post above with screenshots). What worked as a wifi in Mojave is your original card.
You need to add the SSDT to the ACPI folder and the config file:

Adding to OpenCore​

Don't forget that SSDTs need to be added to OpenCore, reminder that .aml is complied, .dsl is code. Add only the .aml file:

• EFI/OC/ACPI
• config.plist -> ACPI -> Add

Click to expand...

Send me your config.plist I will modify it. Just place the SSDT in :

• EFI/OC/ACPI

To be honest, I don't know how to get access to that plist and those directories... This is my first OCLP install.
If you have the time and patience, to instruct me, I'll do it and appreciate it.

Download OpencoreConfigurator. When you run it and click on it in the menu bar it will show several disks and one of them will say Opencore partition. Select mount partition. There are your OC directories and files and the config file:

I re-read your post:

1. you have not disconnected the original airport card and it remains connected inside your Mac pro
2. you did disconnect the cable from original 2.1 BT module
3. The WTXUP BCM94360 gives you WIFI in Mojave but not in Monterey, although it is 'seen' in Monterey
4. you used OCLP to install Monterey

try this:

1. Manually connect using the "other" option on the Wi-Fi menu bar or manually adding the network on the "Network" preference pane in system preferences. Make sure you are logged into iCloud, when I had this problem with an old airport card I could not manually add my wifi ID and password. However I used a network cable to connect to the router in order to complete the set up and once I had Keychain in iCloud set up it automatically connected to the WIFI.
2. if the above does not work, open OCLP and click "Post Install Root Patch" and let it do its thing. At least it will get the old Airport card working. And if it doesn't automatically connect to your wifi then you will need to manually connect using the "other" option on the Wi-Fi menu bar or manually adding the network on the "Network" preference pane in system preferences.

the other suggestions above seem to think you installed OC manually, which is causing confusion.

@zterm Did you do the post install patch with the OCLP? It is a must for devices with obsolete drivers.

I did the Post Reinstall Root Patch once again and did exactly what you suggested.

Now WiFi works fine with the original card.

I noticed that no matter how many times I did the Post Reinstall Root Patch, the Legacy Wireless patch shows up as available, even after having WiFi working fine.

As I broke the BT 2.0 card antenna socket, I am using a dongle for Bluetooth 4.0. In any case, I need 4.0 for some of my devices.

Now I am debating between re-installing the FTXUP card or not, as I don't really need WiFi (except for very occasional fiber connection failures) or I may purchase an iMac WiFi/BT 4.2 card to gain some BT performance and security, but for now, I'm served.

Again, thank you startergo and krakman for your help and patience.

Just a brief noto to say that I re-installed the FTXUP card and everything works fine. I built a cable adapter to feed the BT portion with USB data internally and I even have Airdrop working fine both in Mojave and Monterey.
Now that I no longer have the original BT 2.0 card installed (nor can I install it unless I buy a new one) I don't know if a new Mojave install would install the correct driver and be able to do the post root patch though...

In any case at about 45 euros for the card and the cable, a rather inexpensive way to upgrade wifi and have BT with airdrop working fine.

Hello all - I have a very similar situation with a MacPro 5,1 upgraded with OCLP 0.6.1 .. I did reinstall the Post Install Root Patch (it said it had the latest) and saw legacy WiFi drivers were installed. When I click on the WiFi item, it is on and I can see all the networks but when I choose one, it doesn't ask for the password and doesn't connect (the WiFi icon pulsates from bottom to top like it is trying). I manually tried via Other with the same results. Also went into preferences and removed/readded WiFi in Network. When I boot with my Mojave install on a separate SSD the WiFi works fine. Any ideas ? or do I just need to buy the above card ? If I do, will it work in Mojave. I'm technically good but haven't rolled up my sleeves and taken apart the Mac Pro too much (well I did replace the backplane once). I'm trying to setup the system for sale (MacPro 5,1 Mid 2012, 2 x 2.4 GHz 6-core with 128 GB RAM and AMD Radeon HD 7950). Maybe I just sell w/o WiFi if buyer wants Monterey.
