Tahoe Broadcom wifi malfunction after OCLP-mod 3.1.4

[Norm Bartley]

My AMD system is working perfectly on Tahoe 26.3, except for wifi, which may come as no surprise. I have two hacks, one Intel-based with an i9-14900KF on an Asus Z790m-PLUS MB, and the other is my AMD-based workhorse. Applying the OCLP-mod 3.1.4 root patches to the Intel system worked flawlessly. Everything works. However, wifi on my AMD system works anywhere from 10 seconds to 10 minutes, then dies. Same symptoms using OCLP 3.0.0. Anyone with similar experiences and/or tips? My AMD EFI is pretty bare-bones. My config.plist is attached. I'm using a natively-supported Apple RealTek-based 2.5Gb USB dongle for Ethernet (including the RTL-8125 kernel block in my EFI, just in case!).

Success! AirportBrcmFixup.kext to the rescue. Guessing some sort of incompatibility between my BCM4360 firmware and the root patches. Anyway, reliable operation at last.
