A computing device includes: a wireless communication interface; and a processor configured to: establish a connection with a wireless network; while a network-layer status of the connection is active, monitor attributes of the connection at the wireless communication interface, the attributes including (i) a number of uplink packets transmitted since a most recent downlink packet was received, and (ii) a time period elapsed since the most recent downlink packet was received; determine that the attributes meet recovery criteria indicative of a network-layer interruption in the wireless network; in response to the determination, control the wireless communication interface to initiate a recovery action to resolve the network-layer interruption.

Detection and recovery mechanisms for network interruptions

A method in a client device for updating network configuration parameters, the method comprising: establishing a connection between the client device and an access point connected with a set of other client devices; detecting a connectivity event at the client device; generating a configuration verification request containing current network configuration parameters of the client device; transmitting the configuration verification request for delivery to the set of other client devices; responsive to transmitting the configuration verification request, receiving a configuration verification response from a responding one of the other client devices; and responsive to the configuration verification response indicating non-matching connectivity conditions at the responding client device, initiating a network reconfiguration process at the client device to obtain new network configuration parameters.

System, method and apparatus for updating network configuration parameters

A method in a client device of mitigating connection impact on network infrastructure includes: storing a record of network disconnection events; prior to initiating a network connection, determining whether the record of network disconnection events contains an indication of a local disconnection event; when the record of network disconnection events contains an indication of a local disconnection event, generating and transmitting a scanning request message containing a disconnect indicator; responsive to receiving a response to the scanning request message, determining whether a number of entries in the record of network disconnection events exceeds a threshold; when the number of entries in the record of network disconnection events exceeds the threshold, incrementing a connection interval according to a backoff interval; and sending a connection request message upon expiry of the connection interval.

Methods and systems for mitigating connection impact on network infrastructure

A method and system for an access point assisted active roam scanning includes first and second access points, a switch and a client device. The switch communicates with the first and second access points that operate in a communication network, each access point having a respective operating area. The client device, within the first operating area, includes a wireless transceiver broadcasting first and second probe requests to the first and second access points, respectively, the second probe request being broadcast without receiving a probe response to the first probe request. The first and second access points generate first and second probe responses in response to receiving the first and second probe requests. The switch receives the first and second probe responses and generates a consolidated probe response as a function of the first and second probe responses.
