A scanning module within a non-AP station receives first scan parameter values for performing a first type of scan to obtain a first type of information, and receives second scan parameter values for performing a second type of scan to obtain a second type of information. From the first and second parameter values the scanning module determines combined scan parameter values that satisfy scan requirements for both types of scans. The combined scan parameter values are used to control a sequence of combined scans. A combined scan yields both the first and second type of information. In one example, an IEEE 802.11(n) non-AP station receives 20/40 coexistence scan parameters. The 20/40 parameters and locally-generated background scan parameters are used to determine parameters for performing combined background and 20/40 scans. Reducing the number of scans using combined scans has advantages including increasing data throughput, freeing processing resources, and reducing power consumption.
