    My network adapter disappeared from my computer.


    Hi. So I have a question. About a month ago I did a system restore on my computer to fix a problem when I downloaded a program. When my computer rebooted, my internet connection was gone and there were no wireless networks available.


    I have a Lenovo IdeaPad Yoga 11S. Intel Core i5-3339Y Processor. I have Windows 10 Home version 1809 which was installed on August 23rd, 2019. OS build : 17763.678


    I went into my device manager and clicked on view and then clicked on show hidden devices. It shows network adapters but my Realtek RTL8723AE Wireless LAN 802.11n (n= Wi-Fi 4), Bluetooth 4.0 doesn’t show up.


    However, my Realtek USB 2.0 Card Reader shows up in the Universal Serial Bus Controllers. I’m not sure if that has anything to do with my network adapter.


    How can I fix this issue? Would I need to get a USB ethernet adapter to connect my computer to the internet to fix this issue?

    :)

    Wireless adapter not found in Device Manager


    I ran the Lenovo Solution Center. Network Adapter was not listed in the hardware scanned. Not sure if there is a separate listing for that normally or not.

    Ever since I ran a power cycle the adapter has not appeared in the Device Manager.

    Does anyone believe removing the adapter and putting it back would solve the issue? I would rather not open my computer if there is little chance of it solving the issue. I am a complete novice doing this.

    Not sure if this is relevant but in my Network Adapter in Device Manager there was "Microsoft Kernel Debug Network Adapter". It has since disappeared.

    Wireless network adapter disappearing?

    Hi, I've had an Asus Q400A for about 4 years now. A few months ago, it started doing this thing where I'll be working online, and suddenly I'll lose wifi connection. Then the wifi bars at the bottom of the screen have a yellow exclamation mark on
    them, and then a few seconds later it turns into the Ethernet sign with a red x on it. My wireless adapter disappears completely. If I go to my device manager, all that is listed under my network adapters is the "Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet
    Controller (NDIS 6.30)." I am missing my "Intell Centrino Wireless-N 2230" wireless network adapter. It's like my computer's wifi is completely disabled, and I am only able to connect to the internet via Ethernet. Sometimes I am able to fix it with the troubleshooter
    before the adapter shuts off completely and disappears, as it always turns yellow with the exclamation mark for a few seconds before disappearing. If I am fast enough I can run the troubleshooter and it will reset the wireless network adapter before it disappears.
    But when this doesn't work or I am too late, not even restarting or shutting down my computer will bring it back. It just kind of comes back on its own after I let my computer sit turned off for a few hours. This is INCREDIBLY annoying, as I am a busy high
    school senior, and most of my school work and internship work is done on my computer. I have tried reinstalling the intell wireless adapter driver, and that did not work. What should I do? Is this a hardware problem? I have an Asus Q400A notebook running Windows
    10. I have also tried turning off the option for the computer to turn off the adapter to save battery and that did not work.
