A system and method includes a plurality of wireless and/or wired access points coupled to a network. The network may couple to a wide area network, such as the Internet. In one embodiment, a portable computing device (PCD) may store identification information which uniquely indicates a network provider of a plurality of possible network providers or may also or instead indicate an access or privilege level. When the access point receives the identification information from a PCD, the access point may determine the appropriate network provider for the PCD using the identification information and network access may then be provided. Thus the network system is useable by subscribers of each of the plurality of possible network providers, thereby enabling subscribers to “roam” on various wireless networks. The access information may also include an access level which indicates the user's access or privilege level.
