🔍 Why Internet Stops Working in Windows 11?
Internet issues in Windows 11 are usually caused by communication failure between your PC and router.
- DNS failure — websites not loading
- IP configuration issues — no internet access
- Driver problems — unstable connection
- Firewall or antivirus blocking — apps not working
Restart Router & PC
This clears temporary network bugs.
Change DNS Server
Use Google DNS (8.8.8.8) or Cloudflare (1.1.1.1) to fix most connectivity issues.
Reset Network Stack
This is the most common Windows 11 problem. It means your PC is connected to WiFi but cannot access the internet.
If WiFi disconnects randomly or doesn’t work at all, it’s usually caused by driver or power settings.
If websites are not opening but internet shows connected, the issue is almost always DNS related.
Ethernet issues occur when cable is connected but internet is not working.
These errors usually appear after Windows updates or deep network issues.
Use this logic to quickly identify the problem:
- Internet works on phone → PC issue
- All devices fail → Router or ISP issue
- WiFi connected but no browsing → DNS issue
- Ethernet only problem → Driver or cable issue
- Always keep network drivers updated
- Use reliable DNS servers
- Avoid unnecessary VPN or proxy settings
- Restart router weekly to avoid cache issues
