Based on the aforementioned wireless network card, Embodiment 1 of the present application provides a flow chart of a connection method of a wireless access point, the flow of the method can be performed by the wireless network card, and the method includes the following steps:

S401. When the wireless network card is inserted into the terminal device through the USB interface of the wireless network card, the wireless network card detects whether an encrypted file is stored in the storage medium.

S402. When it is determined that the encrypted file is stored, set the USB interface of the wireless network card to device mode, transmit the encrypted file to the WiFi chip through the USB interface, and the wireless network card decrypts the encrypted file through the WiFi chip to obtain network connection information.

That is to say, the wireless router can send broadcast data to the surroundings, so that the wireless network card can detect the broadcast message, and then determine the network connection information according to the broadcast message, and complete the rapid network configuration. In a possible implementation manner, the wireless network card can parse out one character according to the length of the received broadcast message, a set of lengths, and multiple characters form the network connection information. For example, 10 broadcast frames constitute a group of broadcast frames, so that one character can be parsed out of the 10 broadcast frames, thereby recovering the network connection information. In another possible implementation manner, the broadcast message may carry an encrypted file, and the wireless network card may decrypt it to obtain the encrypted file.

S505. The wireless network card decrypts the encrypted file through the WiFi chip to obtain network connection information.

S506. The wireless network card connects to the wireless access point through the WiFi chip according to the network connection information.

That is to say, on the one hand, if the wireless network card is not pre-configured with an encrypted file, the wireless access point can send a broadcast message to the outside, so that the wireless network card on the terminal device can receive the message, and then decrypt the encrypted file. file to get network connection information. On the other hand, when the wireless network card is applied to the networking of terminal equipment groups, it can also save the user's operation process of importing encrypted files to the wireless network card one by one in advance, simplifying the operation steps and improving the user experience.

As an example, take the network configuration of the UAV group as an example. Because the UAV has no user interface, before, each UAV in the UAV group usually needs to manually configure the network separately. In the present invention, the user only needs to plug in a multi-functional wireless network card on the drone, because encrypted files are imported into the multi-functional wireless network card, the USB interface of the wireless network card is set to device mode, and the Wifi chip of the wireless network card is set to In listening mode, after the wireless network card receives the broadcast message, it can decrypt the encrypted file, decrypt the network connection information obtained from the encrypted file, complete the network configuration operation, and finally access the wireless router or other wireless access point. In this way, it is possible to realize the rapid network distribution of the UAV group and save a long time for network distribution.

To sum up, in the second implementation above, if the encrypted file is not stored in the wireless network card in advance, the encrypted file can also be obtained by using the broadcast message, and the plug-and-play function of the wireless network card can be used to implement the wireless network card Terminal equipment quickly accesses the wireless network.
