A hybrid access system and method using a hybrid access system point of presence router and a remote link adapter to connect a user computer terminal to a network for fast downstream information transfer by high speed information broadcasting with lower speed upstream information transfer through an independent upstream channel to the hybrid access system point of presence router. High speed downstream information transfer passes through a cable TV headend or a TV transmitter or a cell station.

[ What is claimed is:] [1.] In a two way asymmetric network communication system that includes remote computers having respective interfaces for receiving from a server high speed downstream information conveyed over a downstream channel residing in a shared medium and for transmitting lower speed return information over an upstream channel, and wherein said asymmetric network communication system includes a network management unit located at a headend of a broadcast facility for effecting control of one of switching and routing functions in each of said downstream and upstream channels, a method of dynamically setting transmit power level of a remote interface comprising:setting a transmit power level of said remote interface;transmitting from said remote interface at least one indication of said transmit power level; andrepeating said steps of setting and transmitting until confirmation of a confirmed transmit power level is received by said remote interface.
