A method of operating a network device (250; 400), comprising: receiving, by the network device, a plurality of notifications (260, 262, 264) from a plurality of access points (200, 214, 232) in a wireless local area network, WLAN, each notification indicating detection of a particular radar event on a particular wireless communication channel; identifying, by the network device, at least one access point operating on the particular wireless communication channel beside the plurality of access points that fails to detect the particular radar event; and transmitting, by the network device, instructions to the at least one access point, wherein the instructions cause the at least one access point to switch to operate on a different wireless communication channel, wherein identifying the at least one access point further comprises: performing a convex hull calculation based on deployment locations of each of the plurality of access points from which the plurality of notifications are received; and determining that the at least one access point is located inside the convex hull and operates on the particular wireless communication channel, and wherein the method further comprises: determining that at least one client device is associated with the at least one access point; and guiding the at least one client device to associate with a different access point in the WLAN. receiving, by the network device, a plurality of notifications (260, 262, 264) from a plurality of access points (200, 214, 232) in a wireless local area network, WLAN, each notification indicating detection of a particular radar event on a particular wireless communication channel; identifying, by the network device, at least one access point operating on the particular wireless communication channel beside the plurality of access points that fails to detect the particular radar event; and transmitting, by the network device, instructions to the at least one access point, wherein the instructions cause the at least one access point to switch to operate on a different wireless communication channel, wherein identifying the at least one access point further comprises: performing a convex hull calculation based on deployment locations of each of the plurality of access points from which the plurality of notifications are received; and determining that the at least one access point is located inside the convex hull and operates on the particular wireless communication channel, and wherein the method further comprises: determining that at least one client device is associated with the at least one access point; and guiding the at least one client device to associate with a different access point in the WLAN. performing a convex hull calculation based on deployment locations of each of the plurality of access points from which the plurality of notifications are received; and determining that the at least one access point is located inside the convex hull and operates on the particular wireless communication channel, and wherein the method further comprises: determining that at least one client device is associated with the at least one access point; and guiding the at least one client device to associate with a different access point in the WLAN.
