Hello guys,
I come up with solution, I worked almost 20 days in finally find out what is the problem and how to solve it:
First of all,while configuration when it show a message ( AJAX/XHR Error:0xxxxxx) is generated when the configuration is being Saved next a notification that the Yun is offline is then shortly followed by this error, then notification of being online is show actually first connecting to Arduino yun(which acts as access point at beginning) after that connection lost with Arduino yun AC so it says you are offline!.
Next while the configuration finish for some people the setup process till 10%for some 100% but still AJAX/XHR ERROR.
Finally when the setup completes 90% it actually asks you to please redirect to Arduino.local and and popup comes to screen.
Lets discuss the solution now:
1- I think the issue with (offline/online) is solved , don't take this setup serious just ignore it.because its just about you disconnection with Arduino YUN ACCESS POINT.
2- Coming to 10% setup is slow browser please use (chrome) is recommended. In case you are using another browser please clean the cache first.
3- Now, coming to the important part :o
Every wifi has privacy setting, which locks the communication between two devices in same network(YUN with PC).
What you need to do is please change privacy setting of your wifi to allow device communication. By default it is on , please turn if off. Now try to login you will successfully able to login through Arduino.Local.
4- Please don't change Arduino YUN OS or anything else it will just destroy your YUN nothing else. Don't install any Bonjour program incase you are using MAC because the program already there.
5- Please don't try 192.168.240.1 after you connect with a wifi because the wifi gives your YUN a new IP to know the NEW IP of YUN please RUN Arduino IDE>Examples>Bridge>Wifi Status
The bridge will shorty list overall information with the NEW IP on Serial Monitor.
Please let me know if you need more help.
