  • Publication number: 20210282223
    Abstract: In embodiments of the present disclosure, there is provided an approach for connecting an access point (AP) to a mesh network. According to embodiments of the present disclosure, an AP in a recovery mode transmits its identity information to a mesh portal (MPP) in the mesh network via an unsecured connection between the AP and the MPP. Upon a successful verification by the MP, the AP establishes a secured connection with a trusted server to obtain configuration information. The configuration information is used by the AP to establish a mesh link with an MPP or MP in the mesh network automatically. Accordingly, the AP switches from the recovery mode to a normal mode. Embodiments of the present disclosure provide an effective way for deploying and/or recovering an AP in a mesh network, which is more secure and requires no manual operation.
