    I think you're on the wrong track
    If the wireless network adapter is listed and recognized correctly in Device Manager, then the WLan driver has been installed correctly.

    The sporadic WLan disconnection problems could be related to different reasons that are:
    WLan router compatibility problem
    Configuration of the router (kind of encryption WPA WPA2, TKIP, AES)
    WiFi signal strength

    I recommend you to reset the Wlan router.
    Then you test the performance of Wlan using unsecured wireless (of course only for testing purposes)
    Then test the different encryption settings.
    Also test the laptop with or without the power adapter connected.

  • I don't have an icon of the wireless network adapter in the settings of my card.

    I have a laptop but I have no any wireless network settings icon in my "change adapter settings". For more convenience, I put the screenshot here. What can I do for this problem? Please help me.

    Windows in not aware of an installation wireless installed in your computer.  Cause most likely this is the lack of the suitable driver for your specific hardware.

    Check Device Manager and see if it is listed there with a yellow exclamation point.  If this is the case, Windows can see it but it has nothing to do with it, no software device driver.

    Your single source for drivers should be the web site of the manufacturer of your computer.  Go ahead, find your model, then the driver you need.  In many cases these sites more than offer pilot and you may have to do some testing before finding which is the one you need.

    Hi mate,

    Just a simple question: have you activated the wireless network adapter using the hardware on the computer switch portable and key combination FN + F8?

    Satellite L300 is permanently equipped with wireless network card because a friend of mine had the same specifications.

    However, you should try to update the WLAN driver. Check the download page of the Toshiba driver for an update.

    Hi omsaini,

    Thanks for posting your query on the Microsoft Community.

    Sorry to hear that you have to connect to a wireless network adapter trouble.

    To help you further on this subject, it would have been really helpful for us if you had

  • ConfigFree: windows pop up message: sellers application is controlling the wireless network adapter

    Hello

    When I draw a line from nearby wireless networks (with or without WEP security) to the laptop in the middle icon,
    a popup message with the text: the provider application is controlling the wireless card.
    Does anyone know what this message or where I can get the answer to this question?

    After clicking on it you may see far (only the 'ok' button is available), the connecting line with the laptop wireless network disconnects after
    a few seconds.

    Thanks a lot for helping me...

    Hello

    In my opinion this message appears because a 3rd WLan utility configures and controls the WiFi connection!
    There are different possibilities:
    The laptop uses the Intel wireless network adapter and the Intel Proset utility configures the WLan
    Or
    The laptop uses the Atheros WLan card and Atheros Client utility configures the WLan
    Or
    The windows have the option has been enabled and do this job.

    In this case ConfigFree application cannot configure and control the WiFi connection!

  • Will XP work very well on a Vista Satellite Pro L300-153

    Hello

    I'll buy the Toshiba Satellite Pro L300-153 vista laptop, but I intend to use XP on it.
    If I destroy the entire vista and install XP, then use all of the drivers listed on this site for XP, my system would work fine with XP but it's a computer vista laptop?

    I don't see a reason why it should not work well. If Toshiba offers the drivers for this model of laptop, it must be tested.

    For the installation of Windows XP Home edition, I recommend using Windows XP SP2 home edition.

  • Need driver for Satellite Pro L300

    It is the Toshiba Satellite Pro L300 so please help me because I tried so hard and couldn't find a driver.
    And if there is really no driver I'm asking of you I cry me a driver please!
    do you know how I've worked to download it and now there is no drivers?

    In my view, that no company does have drivers but why? Is too recent or something?

    Hope you help me

    Hello!

    What you mean with 86 BIT? There are only two available versions: 32-bit and 64-bit.

    And have you searched the Web from Toshiba site? You can find all the drivers:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    There is no 64-bit drivers for 64 bit and Satellite Pro L300 and I think that nobody will do a driver for you. This forum from a user to s.
    You can search on external Web sites for drivers 64-bit like Intel, Realtek, etc.
