WiFi terminal free networking communication method

The invention discloses a WiFi terminal free networking communication method, which relates to the technical field of wireless network systems and comprises the following steps of: setting a hotspot name of a root node of networking equipment as lan1 in advance, setting a hotspot name as lan2 after a subordinate node of the networking equipment is connected with an upper node, and setting the subordinate node according to the type; after all the nodes are online, reporting the IP of the node and the names of the connected hotspots to the superior node; enabling the superior node to receive the report instruction, store the IP of each subordinate node and the connected hotspot name for broadcasting downwards when the instruction is issued. The networking mode of the tree structure is realized, so that management terminal equipment of a tree authority structure can be realized; the networking mode of the closed-loop structure can realize connection of controllable whole-network equipment at any node; the networ
