Abstract: An information handling system includes a transceiver and a processor. The processor detects a first RF signal of the RF signals received by the transceiver from a first access point (AP), and determines whether an energy level for the first RF signal is above a energy level threshold. If so, the processor determines whether basic service set (BSS) color of the first RF signal is the same as BSS color of a second RF signal from a second AP. If not, the RF signal is coming from a different network. The processor calculates distance to the second AP, determines and configures receive sensitivity energy level threshold based on the calculated distance. If the energy level of the first RF signal is less than the receive sensitivity energy level threshold, the processor continues to receive RF signals from the second AP, and continue to reject RF signals from the interfering network.
