1. A method for connecting a node of a wireless-communication coverage-extension system comprising a backhaul subnetwork in tree form comprising a set of nodes interconnected by wireless or cable by so-called backhaul connections, a plurality of backhaul subnetwork nodes implementing an access-point functionality of one and the same wireless communication network, the wireless-communication coverage-extension system being adapted for making it possible to connect devices to the nodes by means of the wireless communication network or by cable in order to form an initial local area network, the connection method comprising the following steps performed by said node:
determining whether the node has been moved out of the initial local area network;
and, in the case where the node has been moved:
establishing a local area network from the moved node by activating an address-server functionality;
connecting the moved node to a point of access to the internet;
establishing a secure tunnel between the moved node and a master node coordinating the initial local area network;
deactivating the address-server functionality and activating a client functionality of an address server of the initial local area network.
