    I had the same problem till yesterday.. USB tethering working, Wifi Hotspot not..

    All I did was went to Kies Air, configure whatever is required, and Stop.. Well, makes no logical sense but weirdly, it’s working just fine!

    We just moved from USA back to India and the biggest issue I was facing is getting online. I am temporarily living in an office campus and I am not allowed to bring my laptop into the campus. Now I have no way to connect to the internet. I have a Samsung Galaxy SII phone and an iPad3 (wifi version). I figured may be if I get a data plan and make my mobile a hotspot, then I can connect my iPad to the network and use that for browsing. I tried tethering on my phone and everytime it gives me an error ‘Mobile data is not available or invalid sim’. I have an unlimited 2G mobile internet plan from Airtel. Other than when i try tethering, I am able to browse on my mobile without any issues. I checked some forums and there were suggestions to use apps to freeze the tethering manager. Any pointer on what needs to be done?

    I am also having trouble with this. I have the latest 2.3.5 version. For me, it shows that it starts to connect, but does not ask for password and then just says “Windows cannot connect to Android AP” (windows 7). I have tried troubleshooting as well, but this does not help.

    Any advice?

    Many thanks UncleSmitty for your feedback, i’m trying to actiate the hotspt on my galaxy s2 since few days and nothing was working, i even contacted the network carrier and they could not help.
    once i read your feedback, i removed my company email server sitting and it works fine with me… amazing

    but, how can i make it work to be able to have hotspot and configure my company exchange server…?

    It s samsung problem and i cannot beleive how unprofessional they deal with this issue. We buy the most expsnive device on the market and i also face the same problem. i updated yesterday to 2.3.5 latest build and problem persists adding a new problem of NOT saving the Hotsport name and password. That s rediculious how they treat this problem. Tethering is a core function for users of this category and such a phone.
    and let me tell u this: it is NOT operators issue (different operators, different countries, that work with HTC desire) do not work with Galaxy SII.
    ANYONE wants a tethering function DO NOT GO TO SAMSUNG. we need a campaign to force Samsung to react on this. I paid over 500 EURO for this device and cannot use this function since 3 months. Hey Samsung, that sucks.

    Same problem here. It is NOT network related! I insert the SIM card on my SE X10 and it works perfectly, fast and smooth… This is the only disappointment so far on this phone, otherwise it is simply perfect.

    Can we actually check what are the devices/IP that are connected to our hotspot?

    Or is there any app for it?

    • Pradeep Neela

      January 24, 2012 at 12:23 am

      no, not as of now by default you can check which devices are connected!

      I had this problem on my S2. Turned out to be Android 2.3.3 specific; when I upgraded to 2.3.5, the problem was solved and Hotspot tethering started working fine (however it now has a different bug – the parameters such as SSID and passwords are not saved and always revert to their default values 🙁 ).

      Hope this helps.

    I am getting “Security policy restricts use of internet sharing” when i try to enable the hostspot.
    It was working before, suddenly it stopped working, thought that my friend has also SII on the same carrier and it is working.
    I removed all APNs and tried, but still the problem.
    Any one can help plz.

      Finally found out what causes the “Security policy restricts use of Internet sharing” message when trying to use Wifi Tether — it was my company’s Exchange settings. When connecting to the corporate Exchange server for email/calendar/contacts/etc, the corporate settings enforced a security policy that allows them to, among other things (like reset phone to default), restrict Internet sharing.

      Can’t believe it took this long to find it… bleh. Posting here in case others find this info useful.

        you need to by pass the security policy which you can do by rooting the device!

    Can we share Data files like audio vdo or any media file by using WIfi, I know there is Wi-fi Direct given in S2 but to transfer file using it requires same wi-fi direct acces on other divice too… Is there any other way of doing it????

    • NeaL Pradeep

      September 28, 2011 at 2:55 pm

      yes you will be needing the wifi access on both of the device to get / fetch data via wi fi direct!

    • alaa

      September 30, 2011 at 3:10 pm

      wifi direct works fine when there’s another “wifi direct device” in range. the problem is with tethering / hotspot feature / sharing your 3G data connection with your laptop

      • Yogesh Patel

    @alaa – on windows 7??

    Turn WIFI off and then on and try again (on laptop). If still doesnt connect, then click on “troubleshoot” and it will connect. Happens to me too but I always connect this way.

    Good luck!

    • Yogesh Patel

      September 28, 2011 at 9:14 am

      Unable to get your problem.
      Are you trying to connect your Windows 7 PC with the S2 WiFi Hotspot network?

    • alaa

      September 30, 2011 at 3:08 pm

      it might fix the connection for few seconds if I’m lucky, then problem comes back 🙁

    September 27, 2011 at 10:28 pm

    Anyone noticed that wifi hotspot is not working on S2! Try so many times to connect my laptop to the android hotspot, after the success exchange of the very few first bits, I lose internet connection and the connection status says limited connectivity. Tried different laptops, different windows version with no luck. P.S. tethering via USB works perfect.

    • Amit Bhawani

      September 28, 2011 at 11:18 am

      Its just your device, did you try to reset the handset and see if that fixes the problem?

      • alaa

        September 30, 2011 at 3:06 pm

        tried that, not working either 🙁

            September 30, 2011 at 3:09 pm

            Which country are you from? And the Mobile operator? May it possible that your carrier would charge you for using Wi-Fi hotspot.

        • Yogesh Patel

          September 30, 2011 at 3:08 pm

          Any particular issues? checked with your data connections? Does the device shows up on other handsets on available Wi-Fi networks?

      I have installed CM and 4.0.4 and hotspot works great.

      I had the same problem. I stumbled upon the solution though.
      You need to have your hotspot settings in order, then launch Kies Air application.

      Sorted! It worked for me anyway. Can now connect to laptop, Playbook and PS3. . . Good luck.
