A mechanism to enable roaming queries prior to association/authentication while maintaining the advantages of power saving mechanisms can be implemented. The mechanism can involve requiring a mobile terminal to request the desired information a second time so that the access point may take sufficient time to obtain the desired information. The mechanism can be implemented in conjunction with IEEE 802.11.
