Wireless extender secure discovery and provisioning
View Patent ↗According to embodiments of the invention, a first wireless access point discovers a second wireless access point, the first wireless access point tunes its radio and privacy settings, without user input, based upon parameters automatically exchanged in response to the discovery of the second wireless access point, and a secure direct wireless connection is established between the first and second wireless access points using the radio and privacy settings. Adding the first wireless to an existing mesh network includes a determination of the best available direct wireless connection.
1. A system that wirelessly connects to a best candidate wireless access point, the system comprising:
