If your PC or Laptop is having intermittent connectivity to the Internet, you may need to repair and rebuild your TCP/IPC Winsock settings. TCP Winsock defines how software on a Windows Operating System should be able to access the TCP/IP stack, thus how software can connect to the Internet.
If you are experiencing the issue, your LAN connection will appear connected all the time – but your Internet may not always load and you will receive “page cannot be displayed” in your favorite web browser such as Internet Explorer. Winsock corruption can occur from a virus or malware usually installed from other 3rd party software.
To fix and repair TCP Winsock and the Windows TCP/IP stack:
- Open Windows Command Prompt and run as administrator (right-click, “run as administrator)
- Type netsh winsock reset
- You should see this message: Successfully reset the Winsock Catalog.
- Then, type netsh int ip reset
- You will see these messages:
- Resetting Global, OK!
- Resetting Interface, OK!
- Resetting Unicast Address, OK!
- Resetting Neighbor, OK!
- Resetting Path, OK!
- Resetting , failed.
- Access is denied.
- Resetting , OK!
- Restart the computer to complete this action.
- Now, reboot your computer to complete the reset.
After the reboot, verify your WinSock repair. Go to Start -> Run -> Msinfo32 -> OK
Expand Components -> Network -> Protocol
