Abstract
A network is provided that includes a first WLAN infrastructure device (WID) that defines a first subnet, and a wireless client device (WCD) that is initially associated with the first WID. The WCD associates with a 'current' WID when the wireless client device roams from the first subnet to a second subnet defined by the current WID. Upon successful association, the current WID unicasts a first IGMP query message (IGMPQM) to the WCD that has a MAC header including a destination MAC address that is set to a MAC address of the WCD.
