    Realtek 8812BU USB Wireless LAN Fails After KB4522355

    These generic steps have nothing to do with my problem.

    I've reloaded the driver both from Windows Update and from the MFG several times. It seems that KB4522355 has made my Realtek 8812BU Wireless LAN 802.11ac USB NIC incompatible with Windows.

    It seems like instead of random MVP answers someone from Microsoft would offer some specific help.

    Realtek 8812BU Wireless LAN 802.11ac USB NIC not connecting to 802.11ac

    After the July 15, 2016 my wifi card disappeared.

    I have gone back to last week's restore point, but the network adaptor is still "not connected." Something about the crash that occurred after the windows update seems to have convinced the computer that the network adaptor is disconnected, but that seems
    unlikely since nothing moved and this is an internal adaptor (Realtek 8821AE Wireless LAN 802. 11ac PCI-E NIC)
