Abstract: Receiving Wireless Local Area Network (WLAN) packets from co-located access point radios and client device radios may be provided. First, a plurality of switchable gain devices corresponding to an auxiliary radio may be placed into a toggling state in response to the auxiliary radio being placed in a sniffer mode. Next, it may be determined that a primary radio is transmitting within a frequency range of a frequency band. Then, in response to determining that the primary radio is transmitting within the frequency range of the frequency band, a one of the plurality of switchable gain devices corresponding to the frequency band may be placed into a low gain state when the auxiliary radio is sniffing the frequency range of the frequency band.
