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. ## Claims ### Claim 1 An electronic device, comprising: one or more processors; and a memory coupled to the one or more processors and configured to store computer-executable instructions that, when executed by the one or more processors, cause the electronic device to: receive an operating channel of a router; receive a beacon frame from the router, wherein a channel for receiving the beacon frame is the operating channel; learn, based on a country field or a vendor-specific field in the beacon frame, a first channel range supported by the router; learn a second channel range supported by a smart home device; send an operating channel switching instruction to the router when the operating channel is not within the second channel range, wherein the operating channel switching instruction carries the second channel range; and send a WI-FI name and a password of the router to the smart home device. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the instructions further cause the electronic device to: receive a second beacon frame from the smart home device; and learn the second channel range based on a second country field or a second vendor-specific field in the second beacon frame. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the instructions further cause the electronic device to: receive a probe response frame from the smart home device; and learn the second channel range based on a second country field or a second vendor-specific field in the probe response frame. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein before sending the WI-FI name and the password of the router to the smart home device, the instructions further cause the one or more processors to connect to the smart home device. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the instructions further cause the one or more processors to sequentially broadcast, on each channel supported by the electronic device, information about the WI-FI name and the password, and wherein the information carries identification information of the smart home device. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the WI-FI name and the password are sent in a data frame. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the country field includes a first channel number and a number of channels to indicate the first channel range. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the country field includes a maximum transmit power. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein a country code in the country field indicates the first channel range. ### Claim 10 A smart home system, comprising: an electronic device configured to: receive an operating channel of a router; learn a first channel range supported by the router; receive a beacon frame from a smart home device; learn, based on a country field or a vendor specific field in the beacon frame, a second channel range supported by the smart home device; send an operating channel switching instruction to the router when the operating channel is not within the second channel range, wherein the operating channel switching instruction carries the second channel range; and send a WI-FI name and a password of the router to the smart home device; the router configured to: receive the operating channel switching instruction; and switch the operating channel to a second operating channel, wherein the second operating channel is within the first channel range and the second channel range; and the smart home device configured to connect to the router by using the WI-FI name and the password. ### Claim 11 (depends on 10) The smart home system of claim 10, wherein the electronic device is further configured to: receive a second beacon frame from the router, wherein a channel for receiving the second beacon frame is the operating channel; and learn the first channel range based on a second country field or a second vendor specific field in the second beacon frame. ### Claim 12 (depends on 10) The smart home system of claim 10, wherein before the electronic device sends the WI-FI name and the password of the router to the smart home device, the electronic device is further configured to connect to the smart home device. ### Claim 13 (depends on 10) The smart home system of claim 10, wherein the electronic device is further configured to: receive a probe response frame from the router; and learn, based on a second country field or a second vendor specific field in the probe response frame, the first channel range. ### Claim 14 (depends on 10) The smart home system of claim 10, wherein the electronic device is further configured to sequentially broadcast, on each channel supported by the electronic device, information about the WI-FI name and the password, wherein the information carries identification information of the smart home device. ### Claim 15 A method for accessing a network by a smart home device, comprising: receiving an operating channel of a router; receiving a probe response frame from the router, wherein a channel for receiving the probe response frame is the operating channel; learning, based on a country field or a vendor specific field in the probe response frame, a first channel range supported by the router; learning a second channel range supported by the smart home device; sending an operating channel switching instruction to the router when the operating channel is not within the second channel range, wherein the operating channel switching instruction carries the second channel range; and sending a WI-FI name and a password of the router to the smart home device. ### Claim 16 (depends on 15) The method of claim 15, further comprising: receiving a beacon frame from the smart home device; and learning the second channel range based on a second country field or a second vendor specific field in the beacon frame. ### Claim 17 (depends on 15) The method of claim 15, further comprising: receiving a second probe response frame from the smart home device; and learning the second channel range based on a second country field or a second vendor specific field in the second probe response frame. ### Claim 18 (depends on 15) The method of claim 15, wherein before sending the WI-FI name and the password of the router to the smart home device, the method further comprises connecting to the smart home device. ### Claim 19 (depends on 15) The method of claim 15, further comprising sequentially broadcasting, on each channel supported by an electronic device, information about the WI-FI name and the password, wherein the information carries identification information of the smart home device. ### Claim 20 (depends on 15) The method of claim 15, further comprising: prior to receiving the operating channel of the router, sequentially broadcasting, on each channel supported by an electronic device, a probe request frame.
