Referring to fig. 1, fig. 1 is a flowchart of a network distribution method provided in an embodiment of the present invention, where the network distribution method is applied to an electronic device, and the method includes:
step S1: the electronic equipment starts a promiscuous mode to monitor a wireless network data packet;
step S2: the electronic device monitors a plurality of channels in sequence according to a first preset sequence, and when each channel is monitored, whether a channel locking data packet is monitored in a first dwell time preset on a current channel is judged, if yes, the channel locking data packet is used for locking the channel and staying on the locked channel to acquire distribution network information, a target AP is connected according to the acquired distribution network information, if not, the AP existence condition on the current channel is determined by using a beacon frame (beacon frame) and a probe response frame (probe response frame) monitored in the first dwell time on the current channel, and the next channel is monitored according to the first preset sequence, wherein the first dwell time is 100ms-200ms, and is preferably 150ms;
in step S2, the monitoring dwell time of each channel is preset and fixed, when the current channel is monitored, if a channel lock data packet is not monitored on the current channel, the monitoring dwell time is a preset first dwell time, when the dwell time for continuously monitoring the current channel reaches the preset first dwell time, the next channel is switched to, and if a channel lock data packet is monitored before the first dwell time is reached, channel lock is performed, and then the channel lock is not switched to other channels, so as to further monitor a data packet containing distribution network information;
specifically, in this step, when each channel is monitored, when a data packet is received, it is determined whether the currently received data packet is a channel locking data packet and is a beacon frame or a probe response frame, if the currently received data packet is the channel locking data packet, the channel locking data packet is used to lock a channel and stay on the locked channel to acquire distribution network information, and a target AP is connected according to the acquired distribution network information, if the currently received data packet is the channel locking data packet, a configuration channel of an AP and an MAC address of the AP are extracted from the beacon frame or the probe response frame, and the configuration channel of the AP and the MAC address of the AP extracted from the same beacon frame or the probe response frame are associated and recorded, and when the stay time for continuously monitoring the current channel reaches a preset first stay time and the channel is not yet locked, the presence of the AP on the current channel is determined by using the currently recorded information, and the current channel is switched to the next channel for monitoring;

It should be noted that, in the present invention, it is the prior art that the channel locking data packet is a data packet that conforms to the preset channel locking rule, and how to determine whether the received data packet is a channel locking data packet (i.e., how to determine whether the received data packet conforms to the preset channel locking rule) is not described herein again;
in addition, in an embodiment, when it is determined that a channel locking packet is received on a currently monitored channel (i.e., a current channel), the current channel is locked, and the current channel is continuously stayed to acquire the distribution network information.
In the embodiment of the present invention, the second staying time of each channel is determined according to the currently determined AP presence on the channel, for example, for each channel, the second staying time of the channel may be determined immediately after determining the AP presence thereof, then the second staying time is stored, when switching to the current channel and monitoring is started, the second staying time may be directly obtained from the stored information, in addition, the information may also be stored after determining the AP presence, when switching to the current channel and monitoring is started, the AP presence of the current channel is obtained from the stored information, and then the staying time of current channel for this monitoring (i.e., the second staying time of the current channel) is determined according to the obtained information, that is, the execution time of the step "determining the second staying time of the current channel according to the AP presence on the current channel" is not specifically limited by the present invention.
Preferably, in an embodiment, in the step S3, if it is determined that the channel locking data packet is not monitored in the second dwell time on the current channel, the AP existence condition on the current channel is further updated by using the beacon frame and the probe response frame monitored in the second dwell time on the current channel, and when the current channel is monitored next time, the second dwell time determined by the updated AP existence condition on the current channel is taken as the current monitoring dwell time.
The embodiment of the invention provides a network distribution method, which is applied to electronic equipment and comprises the following steps:

in some cases, when the AP sends the data packet on the configured channel, other devices may also receive the data packet on an adjacent channel, for example, the configured channel of an AP is 6 channels, and other devices may not only receive the data packet on 6 channels, but also receive a part of the data packet on 5 channels or 7 channels, but the quality of the data packet received on 5 channels or 7 channels is worse than that of the data packet received on 6 channels, and preferably, in this step, in order to accurately detect the existence of the AP on each channel, this step may include:

It is understood that, in the prior art, when an AP transmits a beacon frame or a probe response frame to the outside, the transmitted beacon frame or probe response frame may include its own MAC address and its own configuration channel, and therefore, when other devices receive the beacon frame or probe response frame, the MAC address and the configuration channel of the AP that transmitted the beacon frame or probe response frame may be extracted from the received beacon frame or probe response frame.
