A wireless gateway controls access through a communication portal to a shared communication link. By way of non-limiting example, the wireless gateway receives input (such as a passcode) from a user operating a communication device in a subscriber domain. The user provides the input to communicate through the communication portal or wireless gateway over the shared communication link. The wireless gateway maps the received input to corresponding access profile information stored in a repository of the wireless gateway hardware. The wireless gateway then provides the communication device access to a remote network over the shared communication link through the communication portal in a manner as specified by the corresponding access profile information.
