    are u running a custom ROM? If so which one. It could be an issue with the ROM.

    If you're allowing google to restore your phone after a factory reset, afterwards go and forget all your wifi networks and see if its any better starting fresh.

    Also, try changing your ip setting mode to static...settings / wifi /select wifi network, click on show advance options and set ip settings to static. That might help.

    After many hours of pain I managed to get 4.1.1 back on with a samsmobile firmware. Later that the phone was connecting to the network but was disconnecting and reconnecting constantly.

    Do you think I should try at OTA update?

    as suggested by terry51 try setting a static ip and see it might solve ure issue. make sure its in the correct range of ure router and outside the dhcp range.

    We run two wireless networks in the office. One for us and one for any visitors. Both are totally separate separate and neither worked.

    Am I reading this right?

    For my S3 to work with wifi I have to root the phone?

    I haven't found a WiFi network I cannot connect to. I am rooted but I didn't have to do anything with Folders from other people's phones or permissions.

    If you have a specific wifi issue, it may be as well creating a new thread.

    This fix will work for any Samsung phone.
    I was having the same issue but someone on this site posted how to fix this issue.
    What you need to do it type in on the number pad *#0011#. You will get a different screen. At this point tap menu and click on wifi. You will see wifi power saver. Below that it will say 'on'. Change 'on' to 'off' by taping it. At that point just exit out by hitting the back button. I made this change a week ago Monday and wifi calling has worked great at work or any other wifi location.
    Two FYIs,
    1. The battery will drain much quicker.
    2. You have to redo the above steps every time you reboot or power th phone off/on.
    I do not have a problem redoing these steps after rebooting but the battery issue bothers me. Any ideas on how to fix that?

    Not a fix, but a work-round

    I use the drop down menu at the top of screen to turn wifi on an off as needed

    tbh you save loads more battery this way too


    what I find slightly annoying is that the number *#0011# can be entered as a contact, it doesn't dial the number (I turn my phone off alot)
