I installed the drivers of this device and it works

iwconfig

here i got:

wlan1     unassociated  Nickname:"<WIFI@REALTEK>"
      Mode:Managed  Frequency=2.412 GHz  Access Point: Not-Associated   
      Sensitivity:0/0  
      Retry:off   RTS thr:off   Fragment thr:off
      Encryption key:off
      Power Management:off

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0

but i can’t switch it to “monitor mode”:

ifconfig wlan1 down
iwconfig wlan1 mode monitor

i got an error:

Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan1 ; Invalid argument.

TL-WN821N ‘s chip : Realtek RTL8192EU. I’m wondering if it doesn’t support “monitor mode” ?

          You can verify if your wifi card support the monitor mode through the iw command.

          There is an example:

           iw list | grep "Supported interface modes" -A10
          

          sample output ( the monitor mode is supported ) :

              Supported interface modes:
               * IBSS
               * managed
               * AP
               * AP/VLAN
               * WDS
               * monitor
               * mesh point
               * P2P-client
               * P2P-GO
               * outside context of a BSS
