1. A topology path obtaining method of a mesh network, which is configured to obtain a topology path of the mesh network, wherein the mesh network comprises a root access point, a plurality of extended access points and at least one client device, the topology path obtaining method of the mesh network comprising:
performing a topology query packet transmitting step to configure the root access point to transmit a topology query packet to the extended access points;
performing a topology response packet transmitting step to configure each of the extended access points to transmit a first topology response packet to the root access point according to the topology query packet, and configure the root access point to generate a second topology response packet by itself; and
performing a topology path generating step to configure the root access point to collect and process a plurality of the first topology response packets of the extended access points and the second topology response packet to generate the topology path;
wherein the topology path comprises a connection relationship between the at least one client device and one of the root access point and the extended access points;
wherein a number of the at least one client device is plural, the client devices comprise a Wi-Fi device and an Ethernet device, and the topology path generating step comprises:
performing a Wi-Fi device connection determining step to configure the root access point to determine that the Wi-Fi device is connected to the root access point or one of the extended access points according to the first topology response packets and the second topology response packet; and
performing an Ethernet device connection determining step to configure the root access point to determine that the Ethernet device is connected to at least one of the root access point and the extended access points according to the first topology response packets and the second topology response packet.
