Method for installing a new node in a wireless home network, the home network consisting of a client network by means of which client devices (Cl1, C12) access an external network by means of a residential gateway, the home network comprising a node (Nel) able to form a mesh network within the home network in order to extend the range of the home network, the method comprises the steps of: - connecting, by the node device, the new node to be installed to the client network supplied by the home network, - detecting, by the node of the home network, a connection of a new node to the client network supplied by the node of the home network, - connecting, by the new node, according to a security protocol of the transport layer, to the node able to form a mesh network, - detecting, by the new node, a new connection coming from a client device to the client device supplied by the new node, - recovering, by the new node, an identifier of the client device and transferring the identifier to the node able to form the mesh network, - receiving, by the node of the home network, an identifier of a client device that is connected to the client network supplied by the new node, - checking, by the node of the home network, whether the client device is a client device known to the home network and, if so: characterised in that: - notifying, by the node of the home network, to the new node, that the client device that is connected to the client network supplied by the new node must be disconnected from the client network, - receiving, by the new node, a notification requesting disconnecting the client device from the client network supplied by the new node, - disconnecting, by the new node, the client device from the client network supplied by the new node, - detecting, by the node of the home network, a connection of the client device to the client network supplied by the node of the home network, - transferring, by the node of the home network, to the new node, identifiers of the mesh network according to a security protocol of the transport layer if the connection of the disconnected client device to the client network supplied by the node of the home network is detected, - receiving, by the node of the home network, from the node able to form a mesh network, identifiers enabling the new node to connect to the mesh network, - configuring, by the node of the home network, identifiers making it possible to finalise the method for installing the new node. - connecting, by the node device, the new node to be installed to the client network supplied by the home network, - detecting, by the node of the home network, a connection of a new node to the client network supplied by the node of the home network, - connecting, by the new node, according to a security protocol of the transport layer, to the node able to form a mesh network, - detecting, by the new node, a new connection coming from a client device to the client device supplied by the new node, - recovering, by the new node, an identifier of the client device and transferring the identifier to the node able to form the mesh network, - receiving, by the node of the home network, an identifier of a client device that is connected to the client network supplied by the new node, - checking, by the node of the home network, whether the client device is a client device known to the home network and, if so: characterised in that: - notifying, by the node of the home network, to the new node, that the client device that is connected to the client network supplied by the new node must be disconnected from the client network, - receiving, by the new node, a notification requesting disconnecting the client device from the client network supplied by the new node, - disconnecting, by the new node, the client device from the client network supplied by the new node, - detecting, by the node of the home network, a connection of the client device to the client network supplied by the node of the home network, - transferring, by the node of the home network, to the new node, identifiers of the mesh network according to a security protocol of the transport layer if the connection of the disconnected client device to the client network supplied by the node of the home network is detected, - receiving, by the node of the home network, from the node able to form a mesh network, identifiers enabling the new node to connect to the mesh network, - configuring, by the node of the home network, identifiers making it possible to finalise the method for installing the new node.
