Solved DNS does not respond on every device that is using my network

[Termer102]

My DNS does not respond on every device. I have tried using commands like these on my laptop:
netsh int ip reset (This worked but only for a short amount of time)
ipconfig /flush dns

I have also tried disabling my antivirus but that didn't resolve the issue.
I even tried resetting my whole router but that also only worked for about short amount of time.

Can you ping router when this happens?

Try: netsh winsock reset

How are you checking DNS when it fails?
When it happens try in cmd: nslookup
enter a website i.e., www.sevenforums.com
and see if you get an IP address in return
if it fails, enter server 8.8.8.8
enter the same website, see if an IP returns

I do get an IP address back. I already tested some websites on my browser and all of them seem to work. Thanks!
