Wi-fi connected but internet is off
hello guys i spent full day to troubleshoot this issue without successi 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

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
