I can only use the Internet with my WiFi modem from my laptop or phone if the PC connected to the modem with a cable is on. If I trun the PC off, then my wireless devices cannot connect to the Internet through the modem.

Why is the modem’s Internet connection dependent on the PC and how can I stop it?

You could purchase an old standalone PC to act as the one you currently have. It would always be on, so the modem would stay connected.

If you want the modem only on sometimes, use Telnet, TeamViewer, SSH, or other remote connection tools that work over LAN. Then use your laptop to turn on the PC.

A dedicated wireless router would also help.
