Whenever you first open your laptop and your card is just working like normal you know you're just at some coffee shop getting online your card is in something called managed mode and if you type IW config you can see that your card is in managed mode.

So what this means is any data that's coming in my card if that data is not meant for me then the WIFI card is going to ignore it, now 99% of time that's awesome because we really don't care about anyone's traffic.

But before even get started just make sure first that your interface card is up whatever one you want to switch, before we try to swap it over we should probably make sure that airmon-ng can detect our card.

Note: here's a problem that you guys may have a lot of people switch over the card and it's fine and then after a while, it turns back into managed normal mode and they're like what the heck I didn't press anything, what's going on?

So if you as an example, want to send de-authentication messages to knock a client off a wifi network, if you want to capture the four-way handshake if you want to run a rogue access point, your wifi adapter needs to support, monitor an injection mode, and often the wifi adapters in laptops don't support those modes.

Another problem is that a lot of us will run Kali Linux or Parrot OS or something else within a virtual machine.
