WARNING: If your Internet connection and your local network use the same port (Ethernet, for example), investigate possible side effects before you turn on Internet sharing. In some cases, sharing your Internet connection disrupts the network. If you use a cable modem, for example, you might unintentionally affect the network settings of other ISP customers, and your ISP might terminate your service.
