Connect phone with wifi

From a computer, if you have USB access already (no root required)

It is even easier to switch to using Wi-Fi, if you already have USB. From a command line on the computer that has the device connected via USB, issue the commands

adb tcpip 5555adb connect 192.168.0.101:5555

Be sure to replace 192.168.0.101 with the IP address that is actually assigned to your device.

You can find the IP address of a tablet in two ways:

Manual IP Discovery:

Go into Android’s WiFi settings, click the menu button in the action bar (the vertical ellipsis), hit Advanced and see the IP address at the bottom of the screen.

Use ADB to discover IP:

Execute the following command via adb:

adb shell ip -f inet addr show wlan0

To tell the ADB daemon return to listening over USB

adb usb
