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
Link Quality:0 Signal level:0 Noise level:0
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
