Why aren't any networks showing when I type airodump-ng <card name>

So I am new in Kali Linux and want to learn the basics. I bought a TP-Link dual boot USB adapter. I can see the device when I type iwconfig wlan0. I can run it on monitor mode also. It works fine. But when I type airodump-ng wlan0 it doesn't give me any errors however it doesn't show any networks either. So I did some research and tried the stuff I found online such as airodump-ng mon0 but when I run the command it gives me an error such as `no such device'. What should I do to see the networks around me? Is there a problem with my wireless card? Please help. And thanks for reading. I think the guy in the video has the same problem. https://www.youtube.com/watch?v=jpzZe7PO8TY
