Hi guys , i'm having a problem with kali linux on virtualbox, my pc doesn't have wifi built in so i am using a usb wifi adapter , but when i open kali linux i can't use wlan0 , only eth0, so does anyone know a solution to this ?

Wang in the cd drive

@LiterallyJesus sorry i don't understand what wang means

He means strike the CD-ROM drive violently until your problem goes away, because virtual machines don't need WiFi, since their connection is provided by their host machine.

Your 'host' machine (PC) provides networking to your 'guest' (Kali). For the sake of abstraction, guest machines do get provides with a standard Ethernet interface (typically some old Intel card or one without a physically equivalent). What networking hardware you have on your host does not matter - it could even be Bluetooth - virtual machines will only ever see the virtual Ethernet adapter it has.

You host by default acts as a router with NAT, or as a switch (bridge). You can configure which network interface is used for this router or switch, but the guest will only ever see a virtual Ethernet adapter.

If you really need to pass the adapter (e.g. if you want to use low level functionality for aircrack, wifite, and so on), pass the USB device to your guest. Note your host system and guest cannot use the device at the same time.

@sbiewald okay so how do i pass it to the guest machine ?

Just search for "virtualbox pass usb" on any search engine for much better information than you'll get in a forum thread.

@bahua This. It's actually built into virtualbox and very easy :)

This guy’s answers sounds like a badly written bot from the 90’s

Cut out the virtual machine. Most Kali tools need low level hardware access. Just install it on a USB stick and boot from it.
