1. A server providing a gateway between two networks, where at least one of the two networks is a wireless network, said server comprising:

  • a radio modem capable of communicating with a first network that operates, at least in part, by wireless communication;

    a network interface capable of communicating with a second network; and

    a digital controller coupled to said radio modem and to said network interface, said digital controller communicating with said first network via said radio modem and communicating with said second network via said network interface, said digital controller passing data packets received from said first network that are destined for said second network to said second network, and passing data packets received from said second network that are destined for said first network to said first network, said digital controller maintaining a map of data packet transmission paths of a plurality of clients of said first network, where a transmission path of a client of said first network to said server can be through one or more of other clients of said first network;

    wherein said digital controller changes the transmission paths of clients to optimize the transmission paths including changing the transmission path from the client to the gateway so that the path to the gateway is chosen from the group consisting essentially of the path to the gateway through the least possible number of additional clients, the path to the gateway through the most robust additional clients, the path to the gateway through the clients with the least amount of traffic, and the path to the gateway through the fastest clients.
