      netsh winsock reset
      netsh int ip reset
  9. Disable IPv6:
    • Temporarily disable IPv6 on your Ethernet adapter by unchecking it in the network adapter settings.
  10. Check for IP Address Conflict:
    • Ensure that no other device on the network has the same IP address as your computer. Use the “ipconfig” command to check your IP address and verify its uniqueness.
  11. Check DHCP Server:
    • Verify that your router’s DHCP server is functioning correctly. Restart your router if needed.
  12. Update Windows:
