1. An access point operable to provide wireless network access to client devices coupled to a wireless network, the access point comprising:

  • a controller that automatically chooses one of a plurality of radio frequencies on which to operate, said controller choosing said frequency after evaluating frequencies on which other access points operate, said controller comprising;

    a. logic for picking a frequency;

    b. logic for transmitting on said frequency;

    c. logic for receiving on said frequency;

    d. logic for evaluating whether other access points are heard on said frequency;

    e. logic for reducing transmission power;

    f. logic for evaluating whether said other access points are still heard on said frequency;

    g. logic for storing the transmission power at which no other access points are heard;

    h. logic for picking a next frequency as the frequency and repeating steps b-g until all of the plurality of frequencies has been picked;

    i. logic for comparing said stored transmission powers;

    j. logic for choosing for operation the frequency associated with the highest stored transmission power.
