disconnect adb of device connected over TCP does not work I run the following command to connect device over TCP ; 

adb connect 192.168.56.102:5555


I am not able now to disconnect it  I even made two attempts : 

 adb disconnect 192.168.56.102:5555 


The second is , I reboot adb 

  adb reboot


Unfortunately, when I run adb devices  , the connection is still there : 

List of devices attached
192.168.56.102:5555 device


Brief, I am looking for the opposite of this answer
I just use &quot;adb disconnect&quot; and it worked fine for me. See the photo below:
