A system and method to enable a wireless device having multiple radios to obtain information about wireless networks without each radio having to independently scan for all available networks. The wireless device downloads information from a remote information server, such that the information is later accessible locally. The local information server may be updated independently according to the preferences of the user. The system enables any of the radios to obtain access information without having to perform time- and power-consuming scanning operations, where the access information is sufficient for the radio to make contact with the wireless network, irrespective of whether the radio is tailored to support that network. The system may include wireless neighborhood map(s) of one or more geographic regions. The wireless device is able to ascertain the wireless network landscape of a region without having to actually reside in the geographic region.
