| 1. A method for establishing communications in a wireless local area network comprising:
obtaining at least one measurement of load for each of a plurality of access point (AP) devices, wherein the plurality of
AP devices comprises a first AP device communicating at a first pre-selected frequency and a second AP device communicating
at a second dynamically selected frequency, the first AP device remains at the preselected frequency and the second AP device
can automatically dynamically change frequencies;
automatically selecting one of the plurality of AP devices as a selected AP device by taking into account the at least one
measurement of load for each of the plurality of AP devices, wherein the first AP device is selected as the selected AP device
when a station (STA) device to be associated with an AP device is not able to automatically dynamically change frequencies
and the second AP device is selected as the selected AP device when the station (STA) device to be associated with an AP device
is able to automatically dynamically change frequencies;
associating the station (STA) device with the selected AP device; and
wherein the selected AP device and the STA device are capable of communicating data within a wireless local area network.
