It seems that wireless ADB has more and more issues each time I update Android Studio. Using 2.1.1, I\'m now unable to connect to my tablet using the command:
I assume you already solved the problem by now. but here is the way to avoid the problem if you are using multiple devices. I used to have the same issue so many times until I understand, how it works. I was also trying to connect multiple devices one after another or trying to connect the same device after a while.
Always make sure to disconnect the older device before you connect the new device:
adb disconnect
after that, you will be easily able to connect new device:
adb tcpip 5555
adb connect
you can always try to ping the device using the ping command, if the ping is not getting acknowledgment then you must have connected to different wifi then your laptop or you haven't connected to wifi at all:
ping
