computer appears to be ok, but DNS respond error
#1
hi

i have a problem on my internet connection.

the problem:

my PC is update to win 10 1803 - KB4467682 (OS Build 17134.441).

At random time i cant browsing, my wifi icon report wifi+internet is ok but i cant't load anything on my browser.

If i troubleshoot the network adapter i recive this message: "Your Computer Appears To Be Correctly Configured, But The Device Or Resource (DNS Server) Is Not Responding"
At this point if i check my ipv4 setting and windows connection info i see this:

As can you see the ipv4 setting seem ok, but in screen on the left with red arrows
type of security: unknown
network channel: 0

on my smartphone i can test the speed of my internet so i exclude modem/router problem.

I have tryed stock windows 10 driver for my wifi adapter and the last aviable but the issue persist.

if i reboot the pc all seem go back working but for half day or few hours.

please help me understand if is a hardware related problem or software / system setting

thanks in advance.

Try booting into safe mode with networking and see if the problem still happens.

I read somewhere that antivirus might be the cause but we'll see.
