I'm running Kali Linux in the latest build of VirtualBox. I noticed that Kali will not pick up the on board WiFi card even though the settings show that VirtualBox sees it. Has anyone been able to get this to work or do you have to use a usb adapter?

VIrtualBox does not emulate WiFi adapter, so you won't see any in the VM, regardless of what you host has with VirtualBox adapters
The only way to make a WiFi adapter appear in the VM is to use a USB adapter which can be made visible to the guest OS.

@SillyString: you don't see host hardware in the guest, period. So if you're going to itemize the host features that you don't see in your virtual machine, then it's going to be a long list.

The VM created by VirtualBox has a simulated ethernet card.
