A system and method for providing access and/or roaming features on a network system. The network system includes a plurality of wireless and/or wired access points coupled to a network. A portable computing device (PCD) of a user may store identification information which uniquely indicates a network provider of a plurality of possible network providers. The identification information may also or instead indicate an access or privilege level of the user. When the access point receives the identification information from a PCD of a user, the access point may determine the appropriate network provider for the portable computing device using the identification information. Network access may then be provided to the portable computing device through the determined network provider.
