An electronic device determines an operating channel of a router, a channel range supported by the router, and a channel range supported by a smart home device. After determining that the operating channel of the router is not within the channel range supported by the smart home device, the electronic device sends an operating channel switching instruction to the router, so that an operating channel after switching is within the channel range supported by the smart home device and sends a Wi-Fi name and a password of the router to the smart home device, so that the smart home device can connect to the router by using the Wi-Fi name and the password of the router.
