here’s a trick that can be applied to all kinds of WiFi issues on Galaxy S3:-


1. Go to your GS3’s dialer and dial *#0011#

2. Now you have to hit the left menu button when you see the “service mode” screen

3. Choose WiFi

4. Turn off the “WiFi power save mode” button if its on

5. Now exit this menu. Turn off and turn on your WiFi. Re-enter the network info if you have already entered it before.


**hope this trick would give you some relief**

My issue after switching to Verizon and buying 2 Galaxy S 3's, mine would not allow wi-fi to turn on at all. After my girlfriend was able to connect immediately and after countless hours, I did the following:
1. Downloaded wondershare mobilego for android and backed up my contacts, pics, and apps
2. Performed a factory reset
I was able to restore all of my phone settings and immediately connected to my home wireless.

My Galaxy S3 was working nicely with my wi-fi router but after changing the WEP security password of my internet connection I couldn't connect to the same network.In advanced wi-fi setting IP address shows ''unavailable''.When I changed in to the previous WEP password it is connected and everything seems fine.what will be the problem?.
I tap in the network name,click ''forget'',again I enter the new password ,nothing happening.please advice me.

Im so very happy this trick works with my sg note 2, too!

Thank u so so much!
