Fix the network (DNS, Winsock, IP)
The classic sequence for "connected, no Internet".
- Open an administrator terminal.
- Flush the DNS cache:
ipconfig /flushdns
- Renew the DHCP lease:
ipconfig /release ipconfig /renew
- Reset the network stacks:
netsh winsock reset netsh int ip reset
- Restart the PC and the router if needed.
