1. A method for identifying one or more access points in one or more channels to facilitate communication, comprising:
identifying an access point in a channel in a first channel band of a first frequency range to facilitate communication with a network, the first channel band comprising a plurality of channels and the first frequency range comprising a plurality of channel bands;
communicating with the network using the identified access point;
maintaining a plurality of priority lists comprising:
a first priority list comprising known channels of the first frequency range, the known channels previously identified by a node as being used by at least one access point;
a second priority list comprising unknown channels of the first frequency range, the unknown channels not previously identified by the node as being used by at least one access point;
a third priority list comprising channels of a second frequency range comprising a plurality of channel bands; and
initiating a scanning sequence to identify one or more access points in one or more channels to facilitate communication, the scanning sequence indicating how often to scan each priority list.
