Sorry for the quotes thing - won't happen again So is there anything else I could try (like pin masking or sth) or should I just look for another card as it could be assumed this one will not work with other methods if it does not work with yours?

Still having the same issue - OS works for a couple minutes, but then the lags come

Did the trick, I can see ARPT device now , but the issue still stands. I also found out that at some point I must've added FakePCIID + FakePCIID_Broadcom... to /L/E, but removing them (with rebuild ofc) did not change anything sadly

Hi, I've been wanting to install Catalina on my Dell E7450 and being able to easily obtain a BCM4350-based card (T77H649 to be exact) I decided to give it a shot. I used the E7450 Catalina bootpack for installation (removing FakePCIID, FakePCIID_Broadcom_WiFi AirportBrcmFixup kexts, as the method apparently does not need these) and this method for the WiFi card. I was able (albeit with troubles) to install the system on my machine, but even after tuning the config based on the information from IORegistryExplorer, it only works for a couple minutes before becoming unresponsive. WiFi itself seems to be working fine (until the system freezes) and pci-aspm-default is being set to 0 according to the IORegistryExplorer. I'm wondering if it's a problem with my config or with the hardware and would be grateful if someone could give it a glance. Thanks! I also tried booting with seemingly all combinations of FixAirport, AddDTGP, FakePCIID kexts and had the same problem each time. FixAirport and AddDTGP didn't also apparently have effect on the IOReg - I couldn't find the ARPT device there. I tried applying pci-aspm-default 0 to PciRoot(0x0)/Pci(0x1c,0x03) device (1 level higher then the card itself), as it is at 0x02 at default, but even though value inject itself worked, the freeze problem persisted.
