Explanation: Interference occurs when one signal overlaps a channel reserved for another signal, causing possible distortion. The best practice for 2.4 GHz WLANs that require multiple APs is to use the non-overlapping channels 1, 6, and 11. These are selected because they are 5 channels apart and therefore minimize the interference with adjacent channels.
