Abstract: A method includes: establishing a connection with a wireless network; performing a roam scan to detect a plurality of access points of the wireless network; determining that a first access point of the plurality of detected access points satisfies a signal strength criterion; determining that a second access point of the plurality of detected access points is physically co-located with the first access point; and selecting a roaming destination from the first access point and the second access point.

Abstract: 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.

Abstract: Systems and method for wireless roaming include operating, via a wireless communication device, a first communication link between the wireless communication device and a first access point using a first media access control (MAC) layer of the wireless communication device; initiating, using a second MAC layer of the wireless communication device, a roaming handover with a second access point while the first communication link remains configured for transmitting and receiving application and/or IP layer communication packets; ceasing transmission and reception of the application and/or IP layer communication packets via the first communication link after the roaming handover has been initiated; and resuming transmission and reception of the application and/or IP layer communication packets with a second communication link between the wireless communication device and the second access point upon completion of the roaming handover.

Abstract: A method in a computing device includes: monitoring, via a communications interface of the computing device, wireless data elements including application data corresponding to a communications application, and non-application data; automatically generating labels based on the application data of the wireless data elements, the labels indicating performance impacts observable in the communications application; selecting a portion of the wireless data elements corresponding to the non-application data; extracting, from each wireless data element of the non-application data, a set of feature values; generating a plurality of samples from the non-application data, each sample including (i) a number of the sets of feature values based on a sample size, and (ii) one of the automatically generated labels; training a classifier based on the plurality of samples, the classifier configured to receive further non-application data and generate a predicted impact indicator selected from the labels; and deploying the classifier.

Abstract: A computing device comprising: a wireless communications interface configured to connect to a network deployed by a plurality of access points; a controller for the wireless communications interface, the controller configured to: initiate an access point scan to identify nearby access points; during the access point scan: obtain a neighbor report, the neighbor report defining a subset of the plurality of access points and an operating channel for each access point in the subset; select a channel to scan and identify an expected access point operating on the selected channel based on the neighbor report; initiate a channel scan to detect the expected access point on the selected channel; and in response to detecting the expected access point, end the channel scan prior to expiry of a default scan time; and connect to a target access point selected based on the access point scan.
