Airdrop Bluetooth and wifi do indeed work native if your using the correct card.
if your using the onboard Intel wifi card then you need to install drivers for it.
if it’s a Broadcom like I use then it should just work.
the only other thing I can think of is your instal must be messed up in some way. Using hackintool clear your cache and rebuild your permissions then once it’s done restart and reset the nvram at the bootpicker and boot back up and see if it kicks it in for you.
the ethernet drivers are installed it should be working. If not same thing as above.
Also don’t rule out your restarting your router.
@ck_zheng the kext I’m using for ethernet only works with Catalina or BigSur, you need to swap it over to this version for Mojave.
Based off of SmallTree's 1.2.5 kext Note: This kext only supports 10.13 and 10.14, for Catalina support use 1.3.0
