Abstract: Aspects of the present disclosure describe various techniques for handling data stall in wireless local area networks (WLANs). These techniques include, for example, a method in which wireless communications are switched at a wireless station from a first network device associated with a first radio access technology (RAT) (e.g., WLAN technology) to a second network device associated with a second RAT (e.g., wireless wide area network (WWAN) technology). The wireless station may then monitor network devices associated with the first RAT, including the first network device. The wireless station may filter results from the monitoring based at least in part on one or more threshold value and identify, based on the filtered results, one of the network devices as suitable for the wireless communications. The wireless communications may then be switched at the wireless station from the second network device to the one network device identified as suitable for the wireless communications.

Abstract: Method, systems, and apparatuses are described for wireless communications. More particularly, a wireless station may connect to a wireless network using a first radio frequency (RF) band and detect a signal strength of the first RF band is greater than a roaming threshold. The wireless station may perform a plurality of scans for support by the wireless network of a second RF band in response to the detected signal strength. Each scan may occur when the signal strength of the first RF band is greater than the roaming threshold. The wireless station may selectively connect to the wireless network using the second RF band based at least in part on the scanning and a throughput supported by the wireless network over the second RF band. The first RF band may be a 2.4 GHz band and the second RF band may be a 5 GHz band.
