  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Sep 05 '22 at 06:21
  • Deleting of previously paired device was a solution for me. – Lukas Poustka Mar 14 '23 at 11:07

By following the 7 steps below, your problem will be solved definitely:

  1. You should add adb to your environment variables. open your environment variable and add Your-SDK=path\platform-tools to environment variables Path.
  2. In your device open Wireless debugging under developer options.(if developer options not exists in your settings you should activate developer mode)
  3. in wireless debugging tap on Pair device with pairing code.
  4. in your Android studio open Terminal and write commands below in terminal.
  5. adb pair Ip-address:port (get Ip address from dialog below)

  1. Insert wifi pairing code. (get pairing code from dialog above)
  2. adb connect IP-address:port (get Ip address & port from dialog below). You've done successfully. congratulations

  • Why does the GUI not work if the solution is this simple?! – John Glen May 19 '23 at 22:08
  • `Successfully paired to 192.168.0.162:41609 failed to connect to '192.168.0.162:41609': Connection refused` I see no options to wi-fi debug after pairing. – Psijic Jul 03 '23 at 09:38

I had a problem like it. Now I use Android Studio Dolphin, WiFi connection works well. Also In Windows Task Manager you can kill adb.exe and try connect your device again.
