Abstract: A channel selecting method includes configuring a main access point to provide a first coverage area in a wireless communication network and performing a channel scanning on a plurality of communication channels to obtain a first area information; assigning an initial preference score to each of the communication channels and adjusting the initial preference score to a first preference score according to the first area information; transmitting a beacon request message to a communication device located in the first coverage area and having a second coverage area; controlling the communication device to perform another channel scanning on the communication channels to obtain a second area information; adjusting the first preference score of each of the communication channels to a second preference score according to the second area information; selecting the communication channel corresponding to the second preference score with a maximum value as a target channel.

Abstract: An access point steering method includes performing a priority list generating step, a measuring requesting step, a determining step and a steering step. The priority list generating step includes selecting priority client from a plurality of clients. The measuring requesting step includes sending a measuring request to one of a plurality of access points, which is signally connected to the at least one priority client, and configuring the priority client to measure a signal strength value between an adjacent access point of the access points and the client. The determining step includes determining whether a connection determining condition of the adjacent access point is corresponding to a predetermined condition. The steering step includes steering the priority client to establish a connection with the adjacent access point when the connection determining condition is corresponding to the predetermined condition.

Abstract: A topology path obtaining method of a mesh network and a system configured to obtain a topology path of the mesh network are provided. In the method, a topology query packet transmitting step is performed to configure a root access point to transmit a topology query packet to a plurality of extended access points. A topology response packet transmitting step is performed 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. A topology path generating step is performed to configure the root access point to collect and process a plurality of the first topology response packets and a second topology response packet to generate the topology path. The topology path includes a connection relationship between at least one client device and one of the root access point and the extended access points.
