Abstract: Provided are a method of registering a home appliance in an Internet-of-Things (IoT) server, and a home appliance. The home appliance performs device registration by obtaining access point information and information of a set-up cloud server from a mobile device connected through device-to-device communication, transmitting a temporary password to the mobile device through the device-to-device communication, establishing a communication connection with the set-up cloud server by using the obtained access point information and the obtained information of the set-up cloud server, obtaining user account information from the set-up cloud server by using the temporary password as an identification key, and providing information of the home appliance and the user account information to an IoT server.

Abstract: A method and an apparatus for controlling a wireless network connection are provided. The method includes detecting a signal strength in a connected wireless network, determining whether the detected signal strength is greater than a first threshold, if the detected signal strength is not greater than the first threshold determining whether an error occurs at least once in data transmission through the connected wireless network, and controlling a connection state of the connected wireless network according to a result of the error determination.
