ADB Wireless + Windows + Non-rooted Device + Hang Issue

I am trying to connect my device via WiFi and following the steps mentioned here.

But when I restart adb in different modes like:

1- adb usb, or

2- adb tcpip 5555

the result is like:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting in TCP mode port: 5555

And it hangs there itself, nothing happens after that.

Is something else needed that I am missing ??
