A method for managing a communication channel used by a plurality of Wi-Fi devices of a Wi-Fi network of the backhaul type for implementing a backhaul network in said Wi-Fi network. A first Wi-Fi device in the plurality performs the method and comprises: detecting a disconnection from an initial channel used by the plurality of Wi-Fi devices for implementing the backhaul network of a second Wi-Fi device in the plurality connected directly to the first Wi-Fi device; listening on a backup channel, to which the second Wi-Fi device is able to migrate to implement the backhaul network in the event of detection, by the second Wi-Fi device, of a radar signal on the initial channel; causing the first Wi-Fi device to migrate to the backup channel in the event of reception on the backup channel by the first Wi-Fi device of a frame containing an identifier of the second device.
