How does companion connect to my computer via wifi? my companion device obviously has no wired connection, but my computer does (and does not have a wifi connection). if both devices are connected to the internet will that work? Can the connection be made from the computer to the companion device (so a firewall port doesn't have to be opened), or am i required to open a firewall port for the wifi device to connect to the computer?
