Abstract
Techniques are provided for selecting an access point (AP) to communicate with from a plurality of candidate access points (APs) when a wireless computing device (WCD) roams in a wireless local area network (WLAN). The WCD stores a pairwise master key (PMK) for each access point that the WCD has previously established a PMK with during authentication. The WCD a plurality of candidate access points and determines an AP statistic (APS) associated with each candidate AP. The WCD then determines an AP rating for each candidate AP based on the APS for the candidate AP and whether the wireless computing device has a pairwise master key stored for the candidate AP. The WCD then selects a particular one of the candidate APs having the highest AP rating as a desired AP of the wireless computing device.
