Abstract: A method of transmitting mesh backhaul data in a WiFi network comprises transmitting the mesh backhaul data between a root node and a first intervening mesh access point via a wireless communication in a first frequency band and transmitting the mesh backhaul data between the first mesh access point and a second mesh access point via a wireless communication in a second frequency band.

Abstract: A computer network device that performs key matching is described. While attempting to establish a secure connection with an electronic device, the computer network device may receive a connection-request message associated with the electronic device. In response, the computer network device may provide a context message addressed to a computer, where the context message requests stored passphrase information associated with the electronic device. Then, the computer network device may receive, associated with the computer, a context response. When the context response indicates that there is no stored passphrase information associated with the electronic device, the computer network device may perform the key matching to identify the passphrase associated with the electronic device. Next, the computer network device may provide, addressed to the computer, the identified passphrase associated with the electronic device or an encryption key corresponding to the identified passphrase for storage by the computer.
