  41. netsetter application not run when i insert it. how to solve

  42. This took me 2 days to find out. If the problem was caused by the system hibernating/sleeping without disconnecting modem it can be easily fixed by restoring the computer to a time is was OK.
    ControlPanel>Open System Restore& select a time it worked correctly
    But it will erase all software & apps installed after restore date.
    Do not use “refresh” computer as it wipe out installed software

  43. Thanks its working

    I have already followed your above tips as suggested by you but no joy so far?

    And moreover, under CONNECTIONS category on the QUICK LAUNCH BAR , MTS INTERNET & MBLAZE USB MODEM still now being displayed and when checking it’s properties, I found it’s occupied COM12 port already and still now connected somehow somewhere in my Winows-8?

    How can I resolve this matter? And moreover, pls. tell me in details how can I update driver of any particular port as MBLZE 3G PLUS data card is unable to connect with Internet na ?

  66. Try the above tips and also update driver of port in which you have placed your device.

  67. Amitava Roy


    Recently I purchased a MTS 3G PLUS data card which is successfully activated and working well in wi-fi mode.

    But after successful installation on my LAPTIOP in WINDOWS-8 platform , i couldn’t connect to Internet so far…giving message like “The remote computer couldn’t may need to change….”

    Please give me a solution to this?

  73. Uninstall the setup and install again. It should solve your problem.

  74. Its Not a hardware problem
    Even i am facing the same problem on Windows 8 & no one has the fix for it.
    Same modem is working on other PCs & laptops properly without any error.

    Further, there is no update for it till now

  75. It may be hardware problem. So contact the retailer where you have bought the modem.
