A network interface of an access point device is configured to transmit to one or more first client stations in a first basic service set (BSS) a first value of a first parameter that indicates a time duration during which the access point device will not dissociate a client station due to not receiving at least one frame from the client station, and transmit to one or more second client stations in a second BSS a second value of the first parameter. The first value of the first parameter is at least an order of magnitude larger than the second value of the first parameter.
