virtualbox.org

Hi,
I've installed virtual box on my Windows 10 and running kali linux on my machine. I have installed extension, but I cant' add my WiFi adapter in virtual box. When I try to add my device from USB setting of my Vbox, it says no devices available, but my host pc is detecting the adapter. Please help me.

Go through USB basics and troubleshooting. If steps 1 through 7 cannot get your device working, please provide the troubleshooting command outputs in step 8, as text in

what wifi adapter do you have ?

if you are using a RealTek RTL88xxAU chipset adapter you need to install driver for it in Kali Linux
I don't think your problem is related to Virtualbox as much as it is to kali Linux drivers,
however, if you are using RTL88xxAU chipset this is how to install the right driver for it (mod edit: 3rd-party link removed)
and if you don't know what chipset your adapter have please let us know the name and I will find the right driver for you
