ADB works over USB, but doesn't work over Wifi
You need to configure your phone for adb wireless before you can use it. If you don't have root, try ADB Wireless (no root).

If you have root, this is the method I always use for adb wireless. It's worked when adb wireless apps don't. Run these commands as root in a terminal emulator.

# kill adbd
toolbox ps | grep adbd | { read -A i &amp;&amp; kill ${i[1]}; }
# set the adb tcp port to 5555
setprop service.adb.tcp.port 5555
# start up adbd
adbd&amp;
# get your Android's local ip
toolbox ifconfig wlan0 | { read -A i &amp;&amp; echo ${i[2]}; }


Then on your pc:

# clear out adb connections
adb kill-server
# connect over the default port 5555
adb connect ANDROID_LOCAL_IP


If you have trouble with this, I would try a few things. Update your PC's adb client. Check your PC firewall, if you have one, to make sure either adb has tcp access or port 5555 is open. Check your Android firewall, if you have one, to make sure adb has wifi access. I use this on Windows and Linux.
