    Wireless Adapter QUALCOMM ATHEROS Missing in device manager and no wifi available


    Hi,

    I'm using an ASUS Vivobook 15 K542UF laptop , i've been experiencing problems with the wireless adapter.

    the wireless network doesnt show even though all mobile devices and other laptops can be connected.


    The wireless adapter under Qualcomm is not available in the device manager menu, not even if i scan for hardware changes,

    uninstall, re-install the adapter plus necessary driver, reboot the computer, nor even if I do a network reset.


    Are there any other solutions to this problem to make the wireless adapter appear?


    Windows 10, 64bit system

    Current driver is 10.0.0.318

    qualcomm atheros model qcnfa435


    pls help, thank you!

    :)

    Wireless Adapter QUALCOMM ATHEROS Missing in device manager and no wifi available

    Hi,

    I'm using an ACER ASPIRE XC-605 desktop, and recently after the 4 Jan 2018 windows update, i've been experiencing problems with the wireless adapter.

    In the morning, when the desktop is started - the internet connection is fine.

    However in the night - at about 11pm, the internet connection always disappears even though all mobile devices and other laptops can be connected.

    The wireless adapter under Qualcomm is not available in the device manager menu, not even if i scan for hardware changes,

    uninstall, re-install the adapter plus necessary driver, reboot the computer, nor even if I do a network reset.

    Are there any other solutions to this problem to make the wireless adapter appear?

    Windows 10, 64bit system

    Current driver is 10.0.0.318

    Qualcomm atheros AR9485

    pls help, thank you!

    Qualcomm Atheros QCA9377 Wireless adapter errors

    Hi All,

    I keep getting disconnected on my Wifi every 10mins or so since 23 Sep 2019. After some time, it would stop connecting. I have to manually go to the device manager and disable the "Qualcomm Atheros QCA9377 Wireless adapter" and re-enable it to get it working.
    Sometimes it works, other times it won't. If it doesn't, restarting the computer helps. I am pretty sure this is a short term solution.

    I have updated the driver and troubleshooting mentioned that it is the latest version. Is there a bug or it is not compatible with the latest windows update.

    Below are the information:

    Windows version: 10.0.18362 build 18362

    Laptop: Asus vivobook S14 X411UF

    Wireless adapter: Qualcomm Atheros QCA9377 Wireless adapter

    Wireless adapter version: 12.0.0.815

    Any help is appreciated. This is getting immensely frustrating!

    Wireless Adapter QUALCOMM ATHEROS Missing in device manager and no wifi available

    Marvell AVASTAR network controller or Qualcomm Atheros QCA61x4A Wireless Network Adapter is missing

    I have XPS13 and it had been working fine. However sice yesterday the wifi tab went missing. It does not show up in network setting. I searched on Microsoft website and it said to go to device manager - network adapter. It said if "Marvell
    AVASTAR network controller or Qualcomm Atheros QCA61x4A Wireless Network Adapter is missing" contact them. These
    are indeed missing And Im wondering what the solution is. Also, why did this suddenly happen?
