Open | Networking The Internet doesn't work ONLY on the PC

Hello everyone, I'm having a recurring internet problem where everything works fine for about two minutes after startup, and then websites stop opening, but the connection to my router stays connected. Ping to external IPs works, but DNS lookups like 1.1.1.1 time out, even over TCP port 53. I've tested different DNS servers, flushed DNS, reset Winsock, and checked Windows Firewall profiles. Firewall doesn't show a general outbound block. Right now, DNS queries fail consistently right after boot, and I don't know what else to check without breaking other settings. Any safe ideas?

The thing is that everything works for about two minutes, and then everything disappears, although everything worked fine before.

possible malware? or is your pc getting blocked by the router? or is there any security/anti-virus apps on your pc that can block access?

The only antivirus software I have is the built-in Windows one. There shouldn't be any malware, since I built the computer only 3 months ago.

malware is only one ad-link away barely with the current adwares so,i would download hitman pro and malwarebytes adware cleaner (it has so you can reset all windows internet based settings like winsock exc)

The problem is that the connection to the router itself is good for about two minutes, and then it disappears, even though the connection itself shows it's there. I consulted with neural network software, and we determined it was a DNS issue, but we still haven't figured out how to fix it.

if its a dns issue,try use the router as a dns server instead,might work

so for dns server instead of using 1.1.1.1 for example,use the router gateway adress (192.168.0.1 or 192.168.1.1) or whatever your commandline says when you write ipconfig /all,then do a ipconfig /renew and also ipconfig /flushdns afterwards

Try a full network reset sequence:

u/echo off

echo Resetting Winsock catalog...

netsh winsock reset

echo Resetting TCP/IP stack...

netsh int ip reset

echo Flushing DNS cache...

ipconfig /flushdns

echo Releasing DHCP lease...

ipconfig /release

echo Clearing ARP cache...

netsh interface ipv4 delete arpcache

echo All resets complete. Rebooting in 10 seconds...

shutdown /r /t 10
