|havent you check both PC and laptop with antivirus, have you? |
Some viruses works as service and try to connect with internet, which is cause of "zero connect to network". I'd do it if I were in ur shoes.
To be sure that the system is clean scan it with a few antiviruses and with free AVZ. It doesnt require the installation on PC. It also checks all services and alarm you about shady services that are going on ur pc.
