Network connection module and network connection method thereof

A network connection module and a network connection method thereof are provided in order to connect a portable electronic device to a node in a mesh network environment. The method includes the following steps: searching out multiple nodes; confirming whether there is a specified node in the multiple nodes; if there is a specified node in the multiple nodes, setting the specified node as a bridging point; if there is no specified node in the multiple nodes, setting the node with the strongest signal in the multiple nodes as a bridging point; and connecting to the other multiple nodes through broadcasting via the bridging point in a mesh network environment. 种网络连接模块及其网络连接的方法，用以供可携式电子装置于网状网络环境下连接至节点。该方法包括以下步骤：搜寻出多个节点；确认多个节点中是否有指定节点；若是，则将指定节点设定为桥接点；若否，则于多个节点中设定信号强度最强的节点为桥接点；以及经由桥接点于网状网络环境中广播连接至其他的多个节点。
