  • Patent number: 8228837
    Abstract: A network device may select between two or more network connections based on a determination of whether the network device can access general Internet resources via an available, higher-preference network without providing additional (e.g., OSI Model Layer Seven) login credentials. In one example, a network device includes a first network interface configured to maintain a connection to a first network gateway, a second network interface configured to connect to a second, different network gateway upon determining that the second network gateway is both available and preferable over the first network gateway, and means for determining whether a remote network resource is currently accessible via the second network gateway. When the remote network resource is accessible via the second network gateway, the second network interface maintains the connection to the second network gateway.
