A method for connecting a node of a wireless-communication coverage-extension system is provided. The node determines whether it has been moved out of an initial local area network. In the case where the node has been moved, a local area network is established from the moved node by activating an address server functionality. The moved node is then connected to a point of access to the internet. A secure tunnel is next established between the moved node and a master node coordinating the initial local area network. The address server functionality is then deactivated and a client functionality of an address server of the initial local area network is activated.
