    Realtek USB Wireless Device fails after application of KB4522355.


    Plug and Play alert fires several times. Device is visible but hidden in Device Manager. Removed and reinstalled KB4522355 with the same result.


    Wasn't this KB supposed to fix WiFi?

  2. REALTEK USB Wireless LAN Adapter setup failed.

    I have been trying to setup a wireless USB adapter from 2 days but i'm failed. It's a "USB 2.0 Wireless 802.11N" Lan Adapter. When i connect it to computer it's driver showing up to the device manager for a few seconds and then vanish. Sometime the driver
    stay up a long time but i can't configure Wifi. When i connected it, in device manager under network adapter it shows "Realtek RTL8188FTV Wireless LAN 802.11n USB 2.0 Network Adapter" some time it comes up with a yellow sign. I'm tried to setting it. My computer
    windows version is 10 pro and it is up to date.

    Realtek 8812BU USB Wireless LAN Fails After KB4522355

    Wireless Lan

    My son accidently deleted or uninstalled Realtek 8821AE Wireless Lan 802.11ac PCI-E NIC from our lenovo pc. Windows 10 system. Now we can not connect to wireless. Is this repairable or do I have to purchase a wireless adaptor now?

    He also deleted the bluetooth function.

    Please help.

    Thanks,

    Rebecca
