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.
