WIFI error in android mobiles

If you have an android mobile and use WIFI(WLAN) often,you may encounter this.There’s nothing to worry about this WIFI error in android mobiles and it may seem unsolvable.Samsung’s galaxy series android phones encounter this WIFI error in most cases.The reason is that the driver is not installed properly(this is the message which it shows,when rectifying it).
it’s a piece of cake,when it comes to solving this problem.
You will never be able to activate WIFI in your android when this problem raises.And you cannot use WIFI hotspot feature

So all that you have to do is,


  • open your keypad and type *#*#526#*#*


And wait for a few seconds till it says that the process was successful.
You wont face any problems hereafter.

IF you face it again,repeat this process.
It’s simple to solve this.

So there’s no fear of the Wifi error in android mobiles.Share this with your friends and this solution has to come to light.

    Hi Abejith,

    I have myself a Samsung Galaxy ACE s5830 which I got just 10 days back and had found this problem where the phone just displayed error while switching on wifi. I then restarted the phone and found that wifi was working fine. After this I began noticing that the phone occasionally (two or three times a day) got hung up with a blank screen while the keypad is locked. When I tried unlocking the keypad, the phone do not respond. I would then have to disconnect the battery or press and hold the power key for 10 seconds to bring my phone back to life. However, I can see that if I switch off wifi, the phone does not get hung up.

    Mine is running Android Froyo and I am yet to take it back to the service center. I hope to get some answers from you experts before that. Do you know of any application which logs system events on the phone so that I can inspect the problem? Thanks in advance for any help to bring my phone back to normalcy.

    • abejithabejith05-14-2011

      Hi there
      I’ve got a galaxy ace too.
      Thanx for your comment.
      I need answers for these:
      -Does the problem that you face, occur during charging your mobile or at all times?
      -did you try the code given in this post?
      -do you have lots of apps on, when you face this problem?
      I can try helping you after you answer these.
      for what you had asked about apps which track system processes,
      You try advanced task killers,
      And do you clear your RAM regularly?
      And you probably won’t have to take your phone for service.
      Please get me the answers for these.I’ll do my best. 🙂

    • TomTom06-07-2011

      Hi Wyctafitrti, when you mention your phone shows a blank screen when locked up, do you mean the screen is on or off? Because I have had the exact same issue with three S5660 (Gio)’s now, but when it’s not responding to anything anymore, the screen is totally off (no backlight whatsoever). Basically, you can’t tell whether the phone is on or off. I guess it’s on because when I press on/off for 10 seconds, powers up again, which is the usual soft reset procedure. If it were off, I’d only have to press the button 2 seconds.

      However, when someone calls me while the phone is in this state, it goes directly to voicemail.

  4. WyctafitrtiWyctafitrti05-14-2011

    Hi Abejith,
    Good to know that you also own one, it is a great phone. Find answers to your questions below. Thank you very much.
    -Does the problem that you face, occur during charging your mobile or at all times? – It happened on both occasions, while charging and while idle but I have not seen it hang, means that it has not happened while I am doing something on it.
    -did you try the code given in this post? – Yes, of course I tried and it was successful but the problem still prevails. 🙁
    -do you have lots of apps on, when you face this problem? – I dont have a lot of applications on my mobile as it is new. I always clear RAM and uninstall apps which are not required.

    In the meantime, I will look for advanced task killers. Thanks again for your help. 🙂

    • abejithabejith05-14-2011

      If you face the problem only while charging, it is normal and happens in all touch phones.but you say that it happens in both situations.
      Ok, I’d like to let you know this:
      Many people face this problem.
      I’ve heard this complaint in many phones which have wifi feature (especially when it’s on)
      So, you needn’t take it for service.I’m sure there’s a solution for it, unless you’ve damaged your hardware.
      I’ll try to get this solved.
      As a temporary solution, try avoiding usage while charging.it’s not a Fault, that you have many apps installed.just don’t keep many ones running.

  5. WyctafitrtiWyctafitrti05-14-2011

    I was wondering whether this would be solved if I upgrade to gingerbread.

  6. K.KK.K05-19-2011

    Hello if I try to solve the wifi error with the code *#*#526#*#* my phone don’t show me again this error but it don’t detect any wifi however the wifi is on and works fine. If i restart my phone it detect and works again fine.

    • abejithabejith05-19-2011

      Then,there isnt any fault in your phone,absolutely.
      Something’s wrong with ur wifi connection.
      And check if u r within range

  7. K.KK.K05-19-2011

    Thank you for your answer of course i am in range but what should i do now?

    • abejithabejith05-19-2011

      Sorry,i dont have the right answers to your problem.
      But i can assure u that ur mobile is in good condition.
      Try checking the wifi connection.but,u seem to mean that it is proper.but just make sure it’s proper and isnt invisible.
      I hope u know that u have to enter the name of ur connection after pressing add new connection,i think the connection is protected with password.so try this.enter its name,rather than just scanning

  8. K.KK.K05-19-2011

    Ok thank you

  9. EneasEneas06-19-2011

    I.ve tried your code but…”Driver loading unsuccessful” what should i do now??:(

    • abejithabejith06-19-2011

      first,thanks for your comment.
      I’ve never heard that such a message is displayed from anybody’s mobile.
      I’ll try to find out why and get back with the solution as soon as possible.

      • EneasEneas06-20-2011

        Thanks for help…hope you’ll find a solution..
        waiting for your reply….

  10. yopuzyopuz06-24-2011

    I have a Samsung galaxy prevail and have never had an issue with my widow. I have recently installed barnacle wick tether so i can watch Netflix on my Xbox. Now my Sufi just says error underneath it. I don’t think barnacle is the problem but i don’t know enough about the system to rule it out. Please help

    • abejithabejith07-05-2011

    How long did it take?
    How large of driver to download?

    • abejithabejith07-26-2011

      it’s a matter of moments.
      btw,it doesnt require GPRS…
      there’s no downloading work here.
      just type the code

  18. custom t shirtscustom t shirts07-30-2011

    I do love the way you have framed this challenge plus it does give us some fodder for thought. Nonetheless, coming from what precisely I have experienced, I just simply trust when the opinions stack on that folks keep on issue and not get started on a tirade of some other news of the day. All the same, thank you for this exceptional piece and whilst I can not agree with this in totality, I respect the standpoint.

  19. LuisLuis08-04-2011

    tnx! problem resolved!

    I tried dialing it in my HTC Inspire 4g, but when I dial the last asterisk *, the dialer just disappears. any suggestions?

    • abejithabejith08-17-2011

      sorry,trry some other strategies.
      thanks for your comment

  25. BorokovicBorokovic08-23-2011

    It said process was succesfull but not work at my Samsung GT-S5570

    I Tried this too
    – several reboots of the device.. just turn it off, leave it dead for a minute, then turn it back on and check wifi after about three of those cycles

    – live battery pull.. with the device on, remove the battery, wait for a minute, then put it back in and check wifi

    – factory data reset.. menu > settings > privacy > factory data reset.. you’ll lose all settings and return the device to original settings.. your SD card will not be touched

  26. dcotterdcotter09-09-2011

    How do I put in a shortcut for this. Doesn’t work if I add to my contacts

    • abejithabejith09-09-2011

      You can add it as a contact.But dont dial it.
      You can just use it as a reference.
      Thanks for your comment.

  27. ZomBeeZomBee10-02-2011


    I did the Wlan test as you said, and the mobile said “Driver Loading successful”, but when I try to turn Wifi on nothing has changed, it doesn’t work.

    I have a Galaxy Mini. I’d appreciate any help. Thanks!

    • abejithabejith10-03-2011

      Does it say “Error”?

      • harryharry10-04-2011

        hi, i have the same problem with my samsung galaxy mini. the wlan test doesnt work on my mini, even it does said “driver load successful” it still have the same problem with the mobile ap (access point). and yes, it does say “error” not “android(the name of the wifi hotspot) is active” any ideas who to fix it in galaxy mini gt s5570?

        • abejithabejith10-04-2011

          So,you have WLAN working fine.
          Only the AP feature is bad?

  28. DroidyDroidy10-03-2011

    If the driver is not properly installed, can’t v install it again?
    This problem is not

  29. DroidyDroidy10-03-2011

    This problem is not solved even when my galaxy ace is upgraded to gingerbread 2.3.4… Isn’t there a permanent solution to this instead of dialling the number every time?

    • abejithabejith10-04-2011

      This is the only known solution.
      I don’t know why it occurs

  30. lespaullespaul10-16-2011

    pressed the command.and nothing happened. wifi still stuck and won’t start. i’m using LG Optimus Black P970.

  31. AyManAyMan10-17-2011

    Hey abejith! Thanks for the great article, a question though:

    The title of the article is “solving the wifi error in android mobiles”.. but this article seems to be only for samsung phones? What if one has this error on a HTC Desire G7? Is it possible to solve it there? :/

    Thanks for taking time to help people!

    • abejithabejith10-17-2011

      I think it’s only for samsung.

      I dont think other phones show such an error

  32. RahulRahul10-17-2011

    Please help

    • abejithabejith10-22-2011

  33. RahulRahul10-22-2011

    yeah indeed great phone 🙂
    lucky to have one 🙂

    The solution to my problem – When the error persists then the driver wil not load .
    What one should do – Restart the phone , turn on the wifi , once it is SWITCHED ON , enter the code and it works like MAGIC 🙂

    Thanks a lot 🙂

  36. airair11-07-2011

    driver loading successful but wifi still wont work.
    in wifi settings it shows that it’s obtaining IP address,it remains like that for a while then it says ‘Remembered’ then ‘Disabled’ then switches back to message obtaining IP address.. 🙁

    • abejithabejith11-09-2011

      Probably some error with the WIFI network.
      Try using another WIFI network.If the problem persists,then you are in a problem,or else not.

  37. LiMaLiMa11-15-2011

    I’ve been surfing on the web more than 3 hours right now, but I by no means discovered any fascinating write-up like yours. It is fairly worth sufficient for me. In my opinion, if all webmasters and bloggers created very good content as you did, the web will likely be much more valuable than ever just before.

  43. ChemGuy1611ChemGuy161112-09-2011

    I don’t understand the instructions. Which keypad am I supposed to type the code into? I tried with the keyboard in a text and with the phone dialing keypad and nothing happens…

            You are supposed to get “driver loading successful”
            or atleast unsuccessful!
            It looks like you have installed some drivers on your android mobile..right?

          • CristyCristy02-04-2012

          • abejithabejith02-04-2012

            Did you root your mobile and install any apps that use root rights?
            Recall if you had installed or messed with the drivers in your phone by connecting with your PC.

      Try unrooting if you have rooted. A factory reset might work.
      If every method fails, let Samsung take responsibility. Take it to them.
