Wi-Fi connected but there is no internet access

  • I have a Samsung Galaxy S Advance (Android upgraded to 4.1.2 Jelly Bean) which I got only one month before. Wi-Fi was initially working great, but now it doesn't have any internet connection even if Wi-Fi gets connected.

    The Wi-Fi gets connected to my laptop, my PC and my father's Android mobile phone, but not on my device. What might be the reason?

    If you go to *Settings→WiFi*, is your AP listed as "connected" – or does it show something different, like `trying to obtain IP address`? The settings of your AP might have gotten messed up. If that's the case, long-tap the AP entry in that list, chose "remove". Switch WiFi off and on again, let it scan for available networks, and try re-adding yours. If there are any errors displayed, please [edit] your question and include the details.

  • Go to wifi settings. click on the access point, remove the password, and input the password again.

    If still doesn't work then follow the steps:

    1. Go to your dialer and type *#*#4636#*#* (*#*#info#*#*)
    2. click on wifi-info > wifi-api
    3. then disconnect > disableNetwork -> enableNetwork

    and you are good to go

    soory please i didnt got you can u tell me again stepwise cause i have removed the password and put the password again but its still not working.... please tell me each and every step please

    go to your dialer pad and then follow the steps written above

  • My father's Galaxy S Advance suddenly lost it's WiFi connectivity one day. I tried the code *#*#4636#*#* and tried to update the WiFi connection by disabling and enabling it, but that didn't work for me.

    Then I came across this blog post which worked:

    1. Turn off WiFi
    2. Turn on the static IP option (you can find this in "Advanced Settings")
    3. Turn on WiFi
    4. Turn off the static IP option - make sure to tap the screen to get the "save" option for this.
    5. Your device should establish a connection
  • You can try changing your wifi network settings from DHCP to Static and a little tweaking of DNS server addresses should work. refer this link for complete solution.

    Under advance settings Change IP Settings from DHCP to Static

    IP Address : Most probably your Gateway address will be change your IP Address my changing last digit in this address use any value preferably between 2 to 20.

    Change DNS1 to

    Change DNS2 to

    Welcome to the Android Enthusiasts! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference (please [edit] your question and do so). Otherwise your question ceases to be helpful in case the link dies.

    I don't know why, but DHCP wouldn't work. After factory resetting the phone and the router, my phone was the only device that wouldn't connect to the internet. I checked the IP address and gateway and it had values that made no sense. So I changed the binding method from DHCP to static and now I can access the internet again :)

  • I also experienced same problem with my Samsung Advance for couple of days.

    I rebooted my phone, reset the factory settings, removed the battery/SIM, turned ON/OFF the static IP option, but it did not work.

    Last thing I did was: I clicked the KIES AIR, and clicked WI-FI. After a few moments, I got a signal to our company Wi-Fi. Try this option, and hope it will work out.

  • My tablet does this too, it shows perfect WiFi connection but apps don't connect. I read in another forum that the date/time gets reset somehow, nobody can figure out how or why and Samsung is oblivious, but...

    Go in and set your date/time to the correct one and voila, it connects! It will reset again eventually and you'll have to go in and do it again but it works.

    I was shocked to see when I read that, that the setting was in fact at January 2012, but I did it and it worked. I also read about seeing the severity from the WPA to A..something, (AEP?) I'm not really familiar with security settings, and I couldn't find where to do it, but many people said that it corrected the problem for them. Lastly, the KIES has also worked for some, I guess turning it on with WiFi makes it connect. I have only tried the date/time setting, but they may all be connected somehow.

  • I had had the same problem with my GS2. I tried all the steps defined here and in other blogs... but it didn't work with my problem.


    I connected my phone to another router, then reconnected it to my own router... it worked perfectly.

  • Go into your WiFi list and forget all of your remembered networks, then reconfigure them.

    1) Why all, if only one has problems? 2) Reconfigure *them* would require to have them all in reach.

  • I had a similar problem, after a lot of struggle finally found out the issue was with the security type, changed the router`s security type from wpa2 to wep128 bits, and it worked fine :)

    Wep is unsafe. It can easily be broken in a few minutes, and generally shouldn't be used anymore. It has about the same security as hiding the SSID, or using MAC address restrictions.

  • try to update your cellphone date and time... ^_^

    While this indeed might be the culprit, would you mind to [edit] your answer, elaborate a little, and let the OP know why?

  • Have you tried your Wi-Fi on any other device? It could be possible that it is connecting as a remote hard drive.

    Excuse me, but I've never heard that Android devices pretend to be a "WiFi harddrive". The WiFi AP obviously works for at least 3 other devices (as the OP describes in the question). The only point left is to try the *Galaxy S* on a different AP, correct. But that has nothing to do with "remote harddrives".

    sometimes you can have a router hooked up as a remote data server, with wireless conectivity, but no inernet

    While that might be, how then would you explain the other mentioned devices being able to connect without issues?
