A network connection method is used for allowing a portable electronic device to connect to a node in a mesh network environment. The method includes the steps of: searching a plurality of nodes; determining whether there is a specific node in the plural of nodes; if yes, setting the specific node as a bridging point; if not, setting a node with the strongest signal strength in the plurality of nodes as the bridge point; and broadcasting to the other nodes via the bridge point under the mesh network environment.
