title: Unable to connect Android ADB over TCP/IP
body: <p>I'm trying to get the Android Debug Bridge working over wifi from my 64-bit Windows 7 desktop computer to my Nexus10.  I connect the device over USB, and then I followed "<a href="https://stackoverflow.com/questions/2604727/how-can-i-connect-to-android-with-adb-over-tcp">How can I connect to Android with ADB over TCP?</a>, but I end up with an error message that it can't connect:</p>
  
  <pre><code>C:\adt-bundle\sdk\platform-tools&gt;adb usb
  restarting in USB mode
  
  C:\adt-bundle\sdk\platform-tools&gt;adb devices -l

  <p>To start debugging this, I tried pinging the Nexus10 from my desktop computer.  Both devices are connected to the same router, by a cable in the case of the desktop computer,  and wirelessly for the Nexus10.  However, I got</p>

  <p>The IP address 192.168.231.61 which returns "Destination host unreachable" is the IP address of my desktop computer.  Although the ping doesn't work, I don't know whether the fact that I can't ping is the source of my ADB problem or whether it's unconnected to the issue.</p>
  
  <p>I'm running Android Debug Bridge version 1.0.31.  Can anyone help?</p>
