    Wifi connecting for a few seconds and then disconnecting and all available networks disappear


    On a desktop running Windows 10 I was connected to my home network using ethernet and once I switched to Wifi I started having the above mentioned problem.

    I have tried with a number of Wifi adaptors and connecting to a number of different Wifi networks, including my phone as a hotspot. In all cases, I am able to connect for a few seconds, then it disconnects and then all the available networks disappear.

    I also tried to disable and uninstall the device from device manager.

    :)

    WiFi appears in Manage Known Networks, not in Show Available Networks

    The list of WiFi connections shown when you click the WiFi icon in the taskbar is a list of all the signals that can currently be seen by the WiFi adapter. The list in Manage Known Networks is a list of all those you have previously successfully connected to, whether or not they are currently available.


    The only plausible explanation is that for a while that WiFi signal had been turned off.

    How to connect to an existing wifi network?

    As you suggested, I tried disabling the ethernet adapter and that caused wi-fi to connect, so the desktop wifi does work. Also, I accessed the router and changed the wireless network name (to wfCHS). Thanks!

    However many problems are still unresolved:

    My laptop behaves just as I want it to. Assuming the router has wifi turned on and the laptop has an ethernet connection, connection to the internet is by ethernet (no private network name), and the wi-fi connection is to my private network "wfCHS", but with no connection to the internet. (If I disconnect the ethernet cable, then wfCHS becomes connected to the internet and stays that way even if I reconnect the cable.) A directory listing shows both laptop and desktop under "Network". Great!

    Things are rather different with the desktop. With Ethernet disabled, the desktop shows a wi-fi connection to the internet. Under Settings > Status it's called "wfCHS" but under Network Connections it's called wfCHS2. If I then re-enable the ethernet connection, the wifi connection stays enabled for a minute or two, then disconnects. Further, the ethernet connection is given the name wfCHS2 under both Status and Network Connections.

    Why does the desktop give an (unwanted) name to the ethernet connection while the laptop doesn't?

    Why does the desktop disconnect its wi-fi connection a minute or so after the ethernet connection is enabled, while the laptop doesn't?

    Why does the desktop give two different names to the wifi connection, depending on whether it's viewed under Status or Network Connections, while the laptop doesn't?

    Why does the laptop show the desktop under Network, while the desktop shows only itself?

    Things are so convoluted that I'd be happy to start over. I've had the desktop "forget" the wi-fi connection as you suggested, then re-established it, but this hasn't helped. Can the ethernet connection also be "forgotten"?

    Really appreciate the help you've given so far!

  4. Wifi connecting for a few seconds and then disconnecting and all available networks disappear

    WIFI disconnecting

    My Wifi is on, but my laptop keeps disconnecting from my wifi. also, when my laptop goes to sleep and then wakeup the wifi does not even show the list of available networks. So after switching on the airplane mode and then turning it back off, the wifi
    networks are listed but either it does not connect to my network or if it does, it gets disconnected as soon as I open any tab .
    I have tried troubleshooting, reinstalling wifi drivers, but nothing seems to fix it.
    This started after windows updated a few weeks back.
    please help
