Networking method, device and system of wireless mesh network

The invention provides a wireless mesh network networking method, device and system, a cloud server receives a network access request sent by a client and sends a network access instruction to a main route, and the main route verifies the network access instruction; and after the main route passes the verification and accesses the wireless mesh network, the main route sends verification result information to the cloud server, and the cloud server stores the identification information of the main route, the identification information of the sub-route and the networking state. According to the scheme, the cost of a wps key is reduced from the aspect of hardware, networking is realized by the cloud, the network is intelligentized, networking is realized by using a private protocol, and the problem that in the prior art, a mesh wireless networking access mode realizes the purpose of successful networking by relying on a wps function to realize interaction between a main route and a sub route, so that the operatio
