Abstract: A wireless local area network comprises an access point and at least one wireless device. The access point indicates in a downlink transmission whether access to the network is based on active scan or polling. The indication is changeable responsive to whether a beacon transmission time is approaching, whether a new scan is to be forced or whether network traffic is about to reach an overload condition.
