Chosen Solution
I bought BCM94331CSDAX (this model is for 2015 15” MacBook Pro model) instead of BCM94360CS that 2015 13” MacBook Pro needs, now I’m having trouble, the WiFi is not working but the Bluetooth works perfectly, when I try to install Windows 10 using BootCamp to test if WiFi and Bluetooth works surprised that it actually worked fine and it’s fast. My question is, is there any work around to manually install the driver for this? I have been using my laptop with USB wireless adapter and I want to use my airport card that I bought. Thank you!
Sadly, you’re between two choices! Rolling back to Catalina so your AirPort board works or if you must go with Big Sure then you’ll need to get the other board. To add to this the BCM94331CSDAX - is a 802.11n board, whereas the BCM94360CS - is a 802.11ax board. So you have the slower I/O board, this will translate into slower transfers if your target offers 802.11ax connections. Basically, you got the older board not the board that came with your system which is why the drivers are not working.
