Thanks to sud007 for this answer  In my case  I only need this part of the solution   In CMD Terminal     adb kill-server    adb tcpip 5555 restarting in TCP mode port  5555    adb connect 192 168 XXX XXX     This bug brings more errors than unable to connect to 192 168 XXX XXX 5555  Connection refused  In my case  I could connect to the device  but when you try to run the app  AndroidStudio stay in Installing APK forever  In this case  I needed to restart the phone too

I solved that issue follow that   Steps    Make sure that Aggressive Wi-Fi to Cellular handover under Networking section in the device s developer options is turned off  Ping continuously from your pc to the device to make sure it s not in network idle mode ping -t 194 68 0 100  windows cmd   unlock the device and even try to surf to some website just to make it get out of the network idle  If ping doesn t work  turn off   on Android Wifi and go back to step 2  When it replies to the ping  connect it via USB  and   adb usb  adb tcpip 5555  adb connect 194 68 0 100 5555   In casr it s still not connected  try to switch the usb connection mode as MTP   PTP   Camera while the device is connected through usb and repeat these steps over again

Try to do port forwarding   adb forward tcp  lt PC port gt  tcp  lt device port gt     like   adb forward tcp 5555 tcp 5555    sounds like 5555 port is captured so use other one  As I know 7612 is empty   Edit   C  Users m gt adb forward tcp 7612 tcp 7612  C  Users m gt adb tcpip 7612 restarting in TCP mode port  7612  C  Users m gt adb connect 192 168 1 12 connected to 192 168 1 12 7612   Be sure that you connect to the right IP address   You can download Network Info 2 to check your IP

I couldn t do it on a Galaxy S3  non rooted    For me it would hang saying        restaring in tcp mode   So i found this series of commands quite useful   First disconnect your device  start from scratch  cmd in admin mode and all the stuff    connect your device and write in CMD Terminal   adb kill-server   control should return as normal  Now type and enter  adb tcpip 5555   you will see          daemon not running  starting it now on port 5037     daemon started successfully     restarting in TCP mode port  5555      and then connect device with  adb connect  lt IP gt    That s how it worked for me after a lot of hassle   UPDATE FOR ANDROID STUDIO  I noticed this doesn t work sometimes  even after correctly repeating steps a number of times  Catch was  sometimes ADB is yet not initialized by Studio unless  Android Tab at the bottom is opened and you see  Initializing Android Studio
