1. A method for noise analysis in a network, comprising:
determining, an amount of upstream noise on each of a plurality of upstream channels;
identifying a noisy upstream channel based on whether the determined amount of upstream noise on a respective channel of the plurality of upstream channels meets a noisy channel criteria; and
identifying a plurality of suspect devices associated with the noisy upstream channel based on respective devices of the plurality of suspect devices meeting a set of one or more suspect criteria, wherein the set of one or more suspect criteria includes a channel criterion that is met for a respective device when the respective device has communicated on the noisy upstream channel.
