Wireless local area networks created by means of modems enable electrical devices, especially smartphones and computers, to connect to the Internet. White goods are known that can connect to the wireless local area network inside the house by means of a card disposed thereon. Thus, the white goods can be controlled by the user by means of the electronic devices such as smartphones, tablets, etc. that are suitable for installing applications. By means of the application, the user can select the functions of the white goods, transfer the selected programs and functions to the white good and get the information related to the operational state of the white good as notifications via the electronic device he/she uses. The card and the application communicate wirelessly by means of a communication protocol. The factors that affect the wireless communication performance are important for the connection of the white good to the network. The transmission power value which, one of these factors, is defined on the card by the producer. Higher transmission power values provide healthier and more accurate communication with the modem. Thus the wireless communication quality is improved. The transmission power value may change due to the ambient temperature. The transmission power value reduces as the ambient temperature increases. Therefore, the wireless communication quality is degraded. The producers set the transmission power value lower than the optimal efficiency value so that the transmission power value does not exceed the standard limit value in lower ambient temperatures. However, the transmission power value that further decreases at room temperature causes problems in the wireless local area connection. The device that is disconnected from the network due to connection problems cannot be controlled.

The optimum transmission power values (Po) change according to the ambient temperature and the optimum transmission power values dependent on the ambient temperature is recorded on the processor (3). By changing the transmission power value (P) according to the changing ambient temperature, the quality of the connection of the household appliance (1) to the local area network is improved.
In an embodiment of the present invention, the household appliance (1) comprises a control card (4) that communicates with the network card (2), a first temperature sensor (5) that is disposed on the control card (4) and that detects the ambient temperature, and the network card (2) having the processor (3) that enables the transmission power value (P) to change according to the temperature information received from the control card (4). The control card (4) controls the operation of the functions of the household appliance (1). By communicating with the network card (2), the control card (4) enables the household appliance (1) to connect to the local area network. The ambient temperature is measured by means of the first temperature sensor (5) disposed on the control card (4). The information related to the measured ambient temperature can be transferred from the control card (4) to the network card (2). Thus, the networkd card (2) enables the transmission power value (P) to reach the optimum value according to the ambient temperature by the network card (2). (Figure 1).
