    RTL8192CU issue on RPi 3

    Hi all!,
    Hope you guys are doing great.

    Before posting this, I really search around everything, but couldn't find anything that really helped me on this.

    I just bought a new wireless adapter (TP-link WN822N), but I am unable to put it on monitor mode.
    I checked at my desktop computer (running Kali), and it is working very well, but when I try to make it work on monitor mode at my raspberry pi 3, I face an error.

    The output when I try to put it on monitor mode:
    PHY Interface Driver Chipset

    phy1 wlan1 ?????? Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter
    cat: /sys/class/ieee80211/phy1/device/net/wlan1mon/type: No such file or directory

    Newly created monitor mode interface wlan1mon is *NOT* in monitor mode.
    Removing non-monitor wlan1mon interface...



    I think it doesn't work because if that ?????? at driver.


    Before trying to make it work on monitor mode, I killed the wireless services using airmon-ng check kill.
    I checked at elinux.org RPi USBWi-Fi Adapters that are fully supported, it says nothing about Debian.

    Do anyone know how to solve this? Any workaround (besides buying an WN722N haha)?

    Thanks in advance.
