Installed dw1820a as I saw below from Herve and wanted to try it out on e7450.
https://osxlatitude.com/forums/topic/11322-dw1820a-broadcom-bcm4350-chipset-under-high-sierramojave/
The way this was as done is by "removing AirPortBrcmNIC plugin kext from IO80211Family kext, patching AirPortBrcm4360 plugin kext with the id of the DW1820A" . It recognizes the chip and for 5-10mins it works but then freezes the whole system.
I did not feel like I needed AirportBrcmFixup kext, so ignored installing it.
Rest of the system is working, I don't really need BT.. Internet works with Ethernet cable, usb hotspot etc. But when I turn on the wifi with dw1820a, works at full blazing speed (5ghz channel) and after some time it freezes.
Attached are the system debug files (EFI, IOreg dump, and LE folder)
Appreciate if I can't get any pointers to resolve this .... TIA
btw, the sys report on wifi dumps this ('switched off the wifi)

Jack, Big Thank you!!! Looks like the older version of the Clover was the culprit.
Thanks again! You are the expert :)) Thank you.

Appreciate if I can get any pointers, please
From Mojave 10.14.2, I updated to 10.14.4 but now having boot issues
Specifically I get
[igpu] Unable to load frame buffer
kextd stall AppleACICPU
This m/c is e7250 w ssd , attached is the EFI CLOVER.
Many thanks in advance

Many thanks, but I figured out that duplicate kexts in /L/E are the culprits. I took a backup and removed most of the kexts except the two in your EFI (copy to /L/E). Now it is super fast boot within 20 secs
Good day.

Just replaced the config.plist, ACPI and kexts folders in the existing EFI from your EFI_7440Mojave.zip
Works like a charm. Thanks again Jack.
If I may ask one last followup, boot up seems longer (may be there are some timeouts for which boot sequence is waiting, not sure), any way to troubleshoot the longer boot sequence? I can definitely live with 2 min boot time, though
Good day.

Thanks and I will get started and keep you posted. Good day.

Thanks so much Jack!
Attached is the CLOVER folder under EFI
PS: I am a total newbie on this
I stay tuned.

Thanks, Merci Hervé!
your update on the BCM4350 guide was very helpful. As I can confirm the dw1820a chips that have the label CN-08PKF4-xxxxxxx should be avoided.
Right now, I found an old dw1560 and replaced the CN-08PKF4 dw1820a card, world is good! So long journey, but for any future google searchers, go with dw1820a with # CN-0VW3T3 as Hervé suggested specifically.
Looks like all Brcm/dw1560 chips are in China/Hongkong as far as eBay goes
Good day.
