Uploading files via wifi leads to panic

[neosoftware]

There is a computer (huanan x79) with BCM94360CD module via pci-e adapter and bigsur 11.4 system installed.
Everything works fine, stern tests pass without problems. But there is one problem associated with uploading big data through the wifi module (when uploading files to the site, when you run the speedtest during the upload test, the first download test will go off with a bang and show about 80 mb / s) in this case, the computer does not turn off completely and the image disappears, I tried to leave the music working at this time and it played from the speakers for about a minute, but there was no image. Before that, the Catalalina system was melting and there were no problems.
Initially I set up the system without cakes
AirportBrcmFixup
BrcmBluetoothInjector
BrcmFirmwareData
BrcmPatchRAM3
but even with the addition of these kexts, nothing has changed
If during the screen shutdown you do not do anything, then after some time the computer will reboot and when the system boots up, the report shows the following information:

tell me how to fix wifi so that the computer does not turn off (if you use a cable connection, then there are no problems, but where this computer is located there is no physical possibility to stretch the cable, so wifi is necessary)

the Catalalina system was melting and there were no problems.

Could you explain it more clearly?

As per your panic log, the panic is due to Watchdog driver. You can simply disable the Watchdog in your config.plist.

You should consider attaching the PR files.

in cataline via wifi Download and upload files work.
In bigsur, only download works via wifi, upload turns off the computer.
Watchdog disabled in the opencore configuration, now the black screen turns off, freezes, and it does not restart

You should consider attaching the PR files.

opencore config files?
