I installed macOS 10.15 Catalina on my Lappy.
Everything work fine but only DW1510 BCM94322HM8L wont work.
DW1510 BCM94322HM8L work OOB on 10.14.x but not on 10.15.
I need help.
Solved By put IO80211Family.kext from macOs 10.14.5 to Clover/Kexts/10.15
Catalina seems to be a read only kext system so modifying kexts to make older hardware work doesn't seem to be possible at this point. However we have had success using Mojave kexts to get hardware to function.
For bluetooth on Broadcom WiFi cards using injectorkext and adding the Mojave bluetooth kexts to System/Library/Extensions folder seems to have solved the connectability issue. Install Mojave kexts and use kext utility to repair permissions and caches before reboot. The Zip contains the Catalina original kexts as a backup in case you want to revert.

For Atheros WiFi we are using Mojave modified with High Sierra kexts. Install in System/Library/Extensions folder and use kext utility to repair.
So at boot you will have two options: boot macOS Mojave or Windows 10
STEP 2 - Using a drive without Windows 10 installed
Disconnect system drive that contains your macOS Mojave install from computer ( This is so that Windows does not overwrite existing macOS Mojave boot loader )
Proceed with a Windows 10 UEFI install.
After installation reconnect macOS Mojave Drive, the Windows installation should now be detected and usable in Clover.
If Windows 10 is not detected or able to boot, then verify you installed Windows 10 as UEFI and not MBR ----> ( Read step 2 - For a drive with Windows 10 installed )
STEP 2 - Using a drive with Windows 10 already installed
Verify your Windows install is GPT / UEFI or MBR / Legacy BIOS.
If Windows install is GPT UEFI then Windows 10 install is ready to use at Clover boot menu, you should be able to boot into Windows directly from Clover boot screen.
But if Windows drive is detected at Clover boot screen, but when booting Windows you get a black screen with a cursor on the top left,
then this is most likely because Windows drive is MBR ( Legacy BIOS ). You can easily convert MBR to GPT using Windows MBR2GPT tool ( this saves hours work having to reinstall Windows 10 and setting up all your applications again )
If Windows 10 install is MBR / Legacy BIOS then simply convert to GPT / UEFI following instructions below ( read video summary and view video )
** To use Windows 10 MBR2GPT tool you must have Windows 10 version 1703 ( creators update ) or later and less than 3 partitions on
the Windows 10 drive **
Confirm Windows 10 drive is MBR Legacy BIOS ( in Windows Disk Management )
Reboot into Windows PE ( Advanced Startup )
Convert from MBR Legacy BIOS to GPT UEFI ( using commands below )
Verify Windows 10 drive has changed to GPT UEFI ( in Windows Disk Management )
After conversion Windows 10 is ready to use at the Clover boot menu
