1. A method for managing IP address leases in a wireless communication coverage extension system comprising a backhaul subnetwork comprising a set of interconnected nodes, a plurality of nodes among said interconnected nodes implementing an access point functionality of the wireless communication coverage extension system, the wireless communication coverage extension system being adapted for communicatively connecting devices to said interconnected nodes by wireless communication or by cable, the method comprising:
implementing a first monitoring of the presence of a main DHCP server by a node of said interconnected nodes to which the main DHCP server is connected;
determining, by said first monitoring, a disconnection of the main DHCP server has occurred; and
in response to the disconnection of the main DHCP server being determined by said first monitoring to have occurred:
requesting activation, in said node implementing said first monitoring, of a backup DHCP server;
implementing a general disconnection of said interconnected nodes and of any device connected to the wireless communication coverage extension system; and
renewing IP address leases, by the backup DHCP server, following said general disconnection,
wherein implementing said general disconnection comprises, by each node of said interconnected nodes:
cancelling its own IP address lease; and
restarting any communication interface of said node that is not used for creating the backhaul subnetwork.
