I want to run wi-fi tools on Linux inside of a Windows 7 host. So I need to have the
wlan0 device listed in my Linux guest.
I have tried VirtualBox and VMware. No luck so far. Is it even possible?
Hardware is laptop's embedded wi-fi card.
As far as the VirtualBox docs' networking section go, no, this isn't possible. Sorry. If you can find a USB Wi-Fi adapter that works with your Linux distro, you might have better luck with that.
VirtualBox networking requires either virtualization of the network hardware, or the use of virtio as a virtual network interface from within the guest. It can, however, pass direct control of USB devices to the guest OS. So, if you really don't want to install Linux to the bare metal, your best bet is finding a USB Wi-Fi adapter that does what you need.
