1. A non-transitory, computer readable medium storing instructions which, when executed by a processing resource, cause a computer to:determine a characteristic of a radio-frequency environment in a wireless local area network, the wireless local area network comprising a subset of network devices;
determine that at least two network devices of the subset of network devices are within a same radio-frequency environment;
indicate a first region to be associated with each network device of the subset of network devices based on a determination that at least two of the subset of network devices are neighbors; and
merge the first region with a second region to identify a new region including a combined subset of network devices affected by the characteristic of the radio-frequency environment in the wireless local area network.
