You are correct in that there are no wifi devices attached to your PCI bus. That is to be expected in a Virtual Machine as VB does not pass thru PCI devices unless you have very special host hardware. I have never been able to get PCI passthru to work. If you really want a separate wifi device for your VM, you will need to install a USB wifi device on the host and use USB passthru to make that hardware available to the guest. That does work.

In most instances, just use the normal virtual networking in VB. The most common is NAT networking, which does most of what is needed for most instances. See Table 6.1 at https://www.virtualbox.org/manual/ch06.html for a list of capabilities.
