A method of batch automatic network configuration of WiFi devices, the method at least comprises the following steps: Deploying, by a network configuration AP, a network configuration AP hotspot for configuration and distribution and releasing a network configuration signal; searching, by a device to be configured, the network configuration signal after the device to be configured enters network configuration state, and calculating whether an AP hotspot sending the network configuration signal currently searched is the network configuration AP hotspot by adopting key conversion algorithm; if yes, the device to be configured connecting to the network configuration AP hotspot; after the device to be configured successfully connects to the network configuration AP hotspot, downloading network configuration data from the network configuration AP hotspot through file transfer protocol, decrypting and verifying the network configuration data, updating network configuration settings, and completing the network configuration; characterized in that said calculating whether an AP hotspot sending the network configuration signal currently searched is the network configuration AP hotspot by adopting key conversion algorithm comprises specifically: obtaining BSSID, encryption mode and support rate information of the AP hotspot sending the network configuration signal currently searched; combining public information of the AP hotspot with a manufacturer specific key thereof to perform BASE64 conversion; hashing a BASE64 conversion result by adopting an SHA algorithm to get a corresponding hash result; selecting a part of specific bits in the hash result and convert them to a string which is used as a hotspot name, and selecting another part of specific bits in the hash result as a WiFi password.
