Patent ID: 7339915

Claim:
In a wireless access point operative to support a plurality of Basic Service Set Identifiers (BSSIDs), each of the BSSIDs mapping by default to a corresponding Service Set Identifier (SSID), and to bridge wireless frames onto a network implementing a plurality of virtual networks, wherein each BSSID maps to a corresponding virtual network, a method comprising: establishing a wireless connection, corresponding to a first BSSID, with a wireless client; accessing a cache of network access information, wherein the network access information for a given wireless client identifies a corresponding BSSID; using, if the wireless client is identified in the cache, the corresponding BSSID as the first BSSID; otherwise using a default BSSID as the first BSSID; receiving, from a remote node connected to the network, network access information for the wireless client, wherein the network access information comprises information identifying a virtual network; storing the received network access information in the cache; and if the virtual network identified in the network access information does not map to the first BSSID, terminating the wireless connection with the wireless client.
