Wireless network cards behave much like normal network cards, but additionally send the message as a wireless "packet" when a strength is set. The modem's address must be used for networking. It can be found through component.modem.address. |

When the network card detects the wake message (a string in the first argument of a network packet), on any port and the machine is off, the machine is started. Works for robots, cases, servers, drones, and tablets. [[component:tunnel|Linked Cards]] provide this same functionality. |
