    Wi-fi connected but internet is off


    hello guys i spent full day to troubleshoot this issue without success i need help

    my spec:
    win 10 x64 OS Build 17134.254
    usb 3.0 wifi adapter based on realtek 8812BU chipset connected to desktop pc with wire extension
    mobo p8z77-vlx

    the problem:

    the device worked very well for about 15 days.now, at random time, even the wifi is ON(the try icon of wifi is full with good signal), i have not Internet, if i try open some web page i receive error like "no internet connection and bla bla ......."

    when this issue succed, if i try a speed test from my smartphone the internet connetion is good without problem, so i assume the problem is from PC - to modem.

    if i try ping the gateway "ping 192.168.0.1 -t" i see a lot of spike lag and drop connection like this.


    what i have tryed:

    - updated wifi adapter driver
    - turn off from device manager "allow this computer turn off the device"
    - setting the wifi at maximum performance from power plane setting
    - uninstall and reinstall the wifi adapter from device manager
    - used different usb3.0 and usb2.0 ports
    - changed 2.4 wifi channel, when i had the issue the channel was free of inteference
    - i also tryed some advanced setting from cmd

    HTML Code:
    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns
    nbtstat -R
    nbtstat -RR
    netsh int ip reset c:\resetlog.txt
    netsh winsock reset
    netsh int tcp set heuristics disabled
    netsh int tcp set global autotuninglevel=disabled
    netsh int tcp set global rss=enabled
    ------------------------------------------------------------------------------------------------

    in the end i dont undestand if the problem is the usb wifi adapter an i need a replacement and the droput is very frustatingfor example in meantime i writing this post the connection wifi+internet is perfectly fine working but i dont know for how many time .... lolI hope any suggestion because i'm out of idea. thanks
