Abstract: A band steering method and a system for a wireless network is disclosed. The network comprises a first and a second radio band, an access node, and a plurality of client devices having single or dual band capability. According to the method, the access node receives a probe request from one of said client devices on the first or second radio band. The probe request indicates whether the client device has single or dual band capability. Thereafter, a probe response is generated by the access node only if the probe request indicates that the client device has single band capability, or if the probe request indicates that the client device has dual band capability and the probe request is received by the access node on the second radio band. On receiving the probe response the client device can use the appropriate radio band for communications within the network.

Abstract: A band steering method for a wireless network comprising access points, for example legacy access points, is disclosed. The network comprises a first and second radio bands, the wireless access point, and one or more client devices. The method comprises receiving an open authentication request at the wireless access point from the client device on one or more of its radio bands. If the open authentication request is received on the second radio band, the method comprises generating an open authentication response, whereas if the open authentication request is received only on the first radio band, the method comprises generating a delayed open authentication response.

Abstract: A method for determining Internet reachability and Internet high availability for a multi-homed device in a network having a plurality of network interfaces includes connecting the multi-homed device to a network interface of interest in the plurality of network interfaces and disabling any functionality of setting a default route entry for the at least one network interface of interest until a determination of Internet reachability is made.

Abstract: A method for detecting a captive portal on a Wi-Fi network in which a device generates a random private IP address and attempts a TCP connection on HTTP port 80 and HTTP port 8080. Upon an unsuccessful TCP connection a determination is made that no captive portal is associated with the Wi-Fi network and upon a successful TCP connection, a determination is made that a captive portal is associated with the Wi-Fi network.

Abstract: Embodiments are disclosed for data synchronization via WIFI direct. In some examples, an in-vehicle computing system of a vehicle includes a wireless communication interface, a processor, and a storage device storing instructions executable by the processor to initiate a connection to a mobile device over a WIFI direct communication link, the in-vehicle computing system being established as a group owner of the WIFI direct link and the mobile device being established as a group client of the WIFI direct link. The instructions are further executable to assign an IP address to the mobile device based on an IP address of the in-vehicle computing system, identify the in-vehicle computing system as a sink for synchronization data communicated over the WIFI direct communication link, and selectively receive the synchronization data from the mobile device over the WIFI direct communication link in accordance with transmission control protocol (TCP) or user datagram protocol (UDP).
