The embodiments of the invention provide a wireless local area network connection method and device. The method includes the following steps that: when it is detected that a wireless local area network connection identifier in an operation panel is triggered, wireless local area network scanning results are obtained; whether the scanning results are matched with the information of wireless local area networks which were connected with an electronic device previously is judged; if the scanning results are not matched with the information of the wireless local area networks which were connected with the electronic device previously, a wireless local area network setting interface is loaded so as to display a part of the scanning results, wherein the displayed scanning results include a first wireless local area network identifier; and when a first wireless local area key for the first wireless local area network identifier is received, the electronic device is connected into a wireless local area network corresponding to the first wireless local area network identifier through the first wireless local area key. With the wireless local area network connection method and device provided by the embodiments of the invention adopted, operations such as opening a system setting interface and selecting a wireless local area network setting interface are omitted, and therefore conveniences in operation can be improved, and the connection speed of the wireless local area network can be improved.
