    The packet loss issue seems to be at random. Some days I have no packet loss and it doesn't even feel like I'm playing on wi-fi. Other days I have packet loss issues the entire day and it's impossible to play online.Even when reseting my PC, modem or even unplugging and plugging back the USB wifi device, the problem persist.Notice how in the screenshot I have connection strength to the router, but the quality is not optimalhttps://gyazo.com/102004ce7c8003112fd800b6a2e28859The quality bar goes up and down every few seconds which I guess relates to the packet lossWhat can I do to improve my

    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.

    LAN packet loss

    Hello ,

    This is a strange one, every test of ping i got a
    packet loss using Ethernet cable but when i use WI-FI adapter it's work fine (no packet loss) .

    Im sure that the router is OK and my hardware & software (motherboard) is OK, i tested with same pc a portable Linux using Ethernet and it's works no packet loss,

    therefore i think there is some problem is windows 10 so i tried to repair it, but i got always packet loss with Ethernet, so what i do ? any suggest ?, before i get made and do a clean install.

    Thank You ,

    ( I have latest windows 10 1809 , and i update all software from my motherboard manufacturer)
