    Microsoft update breaking wifi adapter


    This is something not new and I am the recent victim of Microsoft update KB4515384 which I guess replaces wifi driver to Realtek and then you experience constant network drops. What is Microsoft doing to fix this issue? When can I expect a patch to this problem?

    :)

    Update made wifi adapter disapear


    If the wifi adapter appears in Device manager without any warning triangle but there is no wifi section in Settings, Networks then reinstall the wifi adapter.

    If the wifi adapter appears in Device manager without any warning triangle and there is a wifi section in Settings, Networks then use Settings, Update, Troubleshoot. I'd suggest this sequence:-
    Hardware & devices
    Network adapter
    Internet connections

    Best of luck,
    Denis

    Wifi adapter disappears - goes 'hidden'


    Running Windows 10 on an Acer laptop. Over the past month, the wifi connection dropped without explanation/warning.

    First time, the adapter was visible in Device Manager (with a yellow triangle next to it). An interent search found the suggestion to uninstall it and restart. That worked.

    Today, the connection dropped again. In Device Manager at first I could not see the wifi adapter listed. I clicked to see hidden devices and found the adapter and the Bluetooth (which I had not noticed was missing).

    I again uninstalled, restarted, and both the wifi and bluetooth have returned.

    Anyone any ideas as to what is happening, why it's happening, and what I need to do, please?

    I have attached a screenshot of the DM windows as it is now, showing the wifi adapter name, etc.

    Thanks very much

    Wifi Adapter

    Here are several methods:

    • Look in the user guide - see if 5 GHz WiFi is mentioned.
    • Find that model on the manufacturer's website - see if the manufacturer advertises 5 GHz capability.
    • Look for independent reviews of your model - the reviewer will certainly mention if the adapter supports 5 GHz

    If none of those provide the answer, I can suggest many more ways to find out.
