Method for managing a communication channel used by a plurality of Wi-Fi devices of a Wi-Fi network of the backhaul type in order to implement a backhaul network in said Wi-Fi network, characterised in that the method is executed by a first Wi-Fi device in the plurality and comprises: (a) detecting that a second Wi-Fi device in the plurality connected directly to the first Wi-Fi device has disconnected from an initial channel of an initial sub-band of a frequency band by detecting that no Wi-Fi connection-maintaining frame has been received, on the initial channel, coming from said second Wi-Fi device during a predefined period, said initial channel being used by the plurality of Wi-Fi devices to implement the backhaul network; (b) following this detection, listening on each communication channel of a predefined sub-band, referred to as a backup sub-band of a frequency band, onto which the second Wi-Fi device is able to migrate in order to implement the backhaul network in the event of detection, by the second Wi-Fi device, of a radar signal on the initial channel, the initial and backup sub-bands being different; - in the event of reception by the first Wi-Fi device on a channel , referred to as the backup channel, of said backup sub-band, of a frame containing an identifier of the second device: - causing the first Wi-Fi device to migrate to said backup channel, - checking whether the second device has reconnected to the initial channel; - if the second device has reconnected to the initial channel, causing the first Wi-Fi device to migrate to said backup channel; - if not, waiting for a predefined period and repeating said check ; and - if not, remaining on said initial channel if said first device determines that the second device has reconnected to the initial channel and, if not, repeating the step b). (a) detecting that a second Wi-Fi device in the plurality connected directly to the first Wi-Fi device has disconnected from an initial channel of an initial sub-band of a frequency band by detecting that no Wi-Fi connection-maintaining frame has been received, on the initial channel, coming from said second Wi-Fi device during a predefined period, said initial channel being used by the plurality of Wi-Fi devices to implement the backhaul network; (b) following this detection, listening on each communication channel of a predefined sub-band, referred to as a backup sub-band of a frequency band, onto which the second Wi-Fi device is able to migrate in order to implement the backhaul network in the event of detection, by the second Wi-Fi device, of a radar signal on the initial channel, the initial and backup sub-bands being different; - in the event of reception by the first Wi-Fi device on a channel , referred to as the backup channel, of said backup sub-band, of a frame containing an identifier of the second device: - causing the first Wi-Fi device to migrate to said backup channel, - checking whether the second device has reconnected to the initial channel; - if the second device has reconnected to the initial channel, causing the first Wi-Fi device to migrate to said backup channel; - if not, waiting for a predefined period and repeating said check ; and - if not, remaining on said initial channel if said first device determines that the second device has reconnected to the initial channel and, if not, repeating the step b). - causing the first Wi-Fi device to migrate to said backup channel, - checking whether the second device has reconnected to the initial channel; - if the second device has reconnected to the initial channel, causing the first Wi-Fi device to migrate to said backup channel; - if not, waiting for a predefined period and repeating said check ; and - if not, remaining on said initial channel if said first device determines that the second device has reconnected to the initial channel and, if not, repeating the step b). <EOS>
