I recently bought a TP-LINK TL-WN722N adapter that claims to support Monitor mode and captures any traffic using Wireshark. I tried using Monitor mode with the following commands in Kali Linux,sudo ifconfigeth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500        ether 00:26:22:04:49:62  txqueuelen 1000  (Ethernet)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0        device interrupt 17  lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 1  (Local Loopback)        RX packets 11796  bytes 15836333 (15.1 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 11796  bytes 15836333 (15.1 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0wlan1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 192.168.43.189  netmask 255.255.255.0  broadcast 192.168.43.255        inet6 fe80::9dde:ace6:749e:e297  prefixlen 64  scopeid 0x20<link>        inet6 2405:205:8505:632e:e48a:55c3:960:ab39  prefixlen 64  scopeid 0x0<global>        ether ec:08:6b:16:ce:88  txqueuelen 1000  (Ethernet)        RX packets 3979  bytes 3151582 (3.0 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 3467  bytes 519376 (507.2 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0From this output, I know that my adapter was recognized as wlan1.sudo iwconfigwlan1     IEEE 802.11  ESSID:Redmi            Mode:Managed  Frequency:2.462 GHz  Access Point: AC:C1:EE:BC:17:51             Bit Rate=72.2 Mb/s   Tx-Power=20 dBm             Retry short limit:7   RTS thr:off   Fragment thr:off          Encryption key:off          Power Management:off          Link Quality=70/70  Signal level=-37 dBm            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0          Tx excessive retries:13  Invalid misc:58   Missed beacon:0eth0      no wireless extensions.lo        no wireless extensions.So, at present, the adapter is in Managed mode.

Everything related to Network disappears at the top right corner.Wireshark didn't capture anything. What's wrong?
Cannot use Monitor mode in Kali using TP-LINK TL-WN722N
