connection issues - ADB connect to a device via TCP/IP

I'm trying to use adb connect:

 connect [:]       - connect to a device via TCP/IP
                                 Port 5555 is used by default if no port number is specified.

and this is what I get:

mbp:~ alexus$ adb connect 10.0.0.18
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
unable to connect to 10.0.0.18:5555
mbp:~ alexus$ 

USB debugging is on and 10.0.0.18 is IP of my Android device, I'm able to do it via USB cable w/out any issues... any ideas?

Answer

Try following these instructions:

1) Open the command prompt and navigate to your sdk/platform-tools/ folder.

2) Type adb tcpip 5555 with your device plugged in

3) Type adb connect :5555

4) At this point you unplug your device and type adb logcat

5) At times, such as unplugging/plugging into a USB device, the logcat will become disconnected, just redo steps 3 & 4.
