MP 1,1-5,1 No wifi after upgrading wifi card

[Killacam22]

Hey I guys i upgraded my wifi/bluetooth card to BCM943602CDP using a adapter for mac pro 5,1. Bluetooth works fine, but wifi icon has slash through it. Doesn’t work. I did NVRAM reset (5 beeps) and clean install of Monterey using OCLP on samsung SSD. Any ideas?

Side note: tested on another machine so I know card and adapter work

Remove and redo the OCLP root patches.

Tried that. Says there are no patches to apply

maybe you will try a fresh installation on a spare disk, to test if some settings are botched.

Did you reinstall the OCLP EFI?

I have a similar problem. I am running Monterey on a MacPro 5,1 with OCLP 1.5.0. I bought the WiFi / BT 4.2 card and followed the video instructions. Bluetooth works fine, but WiFi does not work at all. It just keeps searching for WiFi networks. Even when I key in the information (that is not part of a hidden broadcast), it does not work. I contacted the seller who said I needed the latest drivers...The Broadcomm drivers are built into Monterey, so they don't know what they are talking about. I don't know if I have a defective card or I am missing something.

I tried booting from two different Monterey boot disks and have the same result with both.

Do a clean install with a spare drive and see if the card works or not.

When you do a install with OCLP, the root patches remove the drivers for all the other cards but the card that you had installed in the Mac Pro while doing the OCLP install, this is specially true with GPU and AirPort cards.
