1. A device, comprising:
at least one antenna; and
a circuit, communicating with one or more agent devices through the at least one antenna, wherein the device and the one or more agent devices form a mesh network;
wherein the circuit periodically obtains a scan report from each agent device, and determines whether an OBSS (overlapping basic service set) airtime in the scan report of each agent device satisfies a first predetermined condition,
wherein in response to the OBSS airtime of each agent device satisfying the first predetermined condition, the circuit disables spatial reuse of each agent device by updating a plurality of spatial-reuse parameters for each agent device, wherein the spatial-reuse parameters further comprise a plurality of spatial-reuse offset parameters, and the circuit updates the spatial-reuse offset parameters to 0.
