How can I find a specific device while on airodump-ng?

I am currently running a linux machine on Oracle Virtual Box. I am learning penetration testing, however when I try to run airodump-ng wlan0 , it shows networks which it is supposed to do. But the issue is when i run airodump-ng --bssid 11:22:33:44:55:66 --channel 1 --write test wlan0 , all of those are replaced with correct values. It writes it in a .cap document and I run it in wireshark. I cant seem to find the one device I am looking for. The reason I am looking for a device is because I want to run aireplay-ng --deauth 10000 -a 11:22:33:44:55:66 -c [ip for the device] wlan0 , it doesnt do anything. I have already tried setting up a hotspot and only connecting one device to this network and running the deauth command but nothing happens to the device. I have also gone into the device and finding its mac address and run the command but to no avail. Is there a solution? I am out of my depth here so bear with me :slight_smile:
