The wireless local area network access device 200 and the wireless local area network access device 300 can operate in a first mode of operation or a second mode of operation. Of course, the WLAN access device can also work in other modes of operation. The first working mode is an open mode, and the wireless local area network access device in the open mode does not need to provide an access password when the terminal accesses the network. The second working mode is a non-open mode. When the wireless LAN access device in the non-open mode performs network access to the terminal, the terminal needs to provide an access password and verify the access password provided by the terminal. The first working mode corresponds to the first transmit power or the first transmit power range, and the second working mode corresponds to the second transmit power or the second transmit power range, where the first transmit power is smaller than the second transmit power, or the first transmit power range Any one of the values is smaller than any one of the second transmit power ranges. That is, in an example, when the wireless local area network access device is in the first working mode, the wireless signal transmission power sent by the wireless local area network circuit (Wi-Fi module) is the first transmission power, and the wireless local area network access device is in the second working mode. The wireless signal transmission power transmitted by the wireless local area network circuit (Wi-Fi module) is the second transmission power; in another example, when the wireless local area network access device is in the first working mode, the wireless local area network circuit (Wi-Fi module) The transmitted wireless signal transmission power is any value within the first transmit power range, and when the wireless local area network access device is in the second working mode, the wireless signal transmitted by the wireless local area network circuit (Wi-Fi module) is the second transmit power range. Any value within.

In a specific implementation, a set value may be preset, and when the wireless local area network access device is switched from the second working mode to the first working mode, the signal transmitting power of the wireless local area network access device is reduced to the first transmitting power, where The first transmit power is less than the set value, and when the wireless local area network access device is switched from the second working mode to the first working mode, the signal transmission power of the wireless local area network access device is increased to the second transmit power, and the second transmit The power is equal to or greater than the set value.

Generally, the size of the second transmit power is preset and fixed, and the maximum coverage of the wireless local area network access device can be characterized. The size of the first transmit power may also be preset and fixed, and may also allow the user to set it according to needs, but not greater than the second transmit power. For example, a user setting option may be provided in the configuration interface of the wireless local area network access device, by which the user may select or input the size of the first transmit power. In specific implementation, the size of the first transmit power may be represented by a radius of the coverage range.

The wireless local area network access device 200 or the wireless local area network access device 300 can switch to the first working mode according to the first access instruction, and switch to the second working mode according to the second access instruction. The first access instruction and the second access instruction may be issued by a user as needed. The following is exemplarily listed how several first access instructions or second access instructions are sent:

Mode 1

In the mode 1, the WLAN access device is provided with a button, and the button is electrically connected to the processor, and the user can press or touch or otherwise operate the button to issue the first access command and/or the second access command. . The button can be set on the front panel or the rear panel of the wireless LAN access device to facilitate user operation. Further, the WLAN access device may further be configured with an indicator light for indicating a current working mode, such as indicating whether the current working mode is in the first working mode or the second working mode.

The number of buttons can be one or more. If the number of buttons is multiple, one of the buttons can be triggered to issue a first access command, and the other button can be triggered to issue a second access command. If the number of the buttons is one, the button may have two limit states (the first limit state and the second limit state), for example, the button state corresponding to the first limit state is that the button is pressed, and the second limit The state corresponding to the bit state is that the button is raised. When the button is triggered to be in the first limit state, the first access command may be issued, and when the button is triggered to be in the second limit state, the second access command may be issued. For example, when the button is pressed and remains pressed, the wireless LAN access device switches to the first working mode and maintains the working mode. When the button is raised, the wireless local area network access device switches to the first Two working modes. In another example, if the number of buttons is one, then switching between the first access command and the second access command is also possible. The processor may also determine, according to the current working mode of the WLAN access device, an instruction issued when the button is triggered. For example, when the button is triggered, the processor determines that the current WLAN access device is in the first working mode. Then, it can be determined that the command issued by the button is triggered by the second access command, and when the button is triggered, the processor determines that the current wireless LAN access device is in the second working mode, and then determines that the button is triggered. The instruction is the first access instruction.

Mode 2

In the mode 2, the configuration user interface of the WLAN access device provides a function button for triggering the first access instruction and for triggering the second access instruction, and the user needs to switch the working mode of the WLAN access device. The user interface of the wireless local area network access device may be accessed first, and the first access instruction or the second access instruction is issued according to the function button provided in the user interface.

The above modes 1 and 2 are merely illustrative examples. In other embodiments, other manners of triggering the first access command and the second access command, such as a voice control mode or a wireless remote control mode, may also be supported, which are not enumerated herein. Certainly, the wireless local area network access device provided by the embodiment of the present application can support the foregoing one triggering manner, and can also support the foregoing multiple triggering manners.

It should be noted that, in the above example, the first access command is used to trigger the WLAN access device to enter the first working mode, and the second access command is used to trigger the WLAN access device to enter the second working mode. In other examples, the WLAN access device does not define the first working mode and the second working mode. In this case, the first access command may trigger the WLAN access device to reduce the wireless signal transmit power and indicate the wireless connection. The inbound device cancels the access verification of the terminal, and the reduced transmit power of the wireless signal is lower than the set value, and the second access command may trigger the wireless local area network access device to increase the wireless signal transmit power and instruct the wireless access device to restore the pair. The access verification of the terminal, the transmitted power of the improved wireless signal is not lower than the above set value.

Based on the WLAN access device shown in FIG. 2A or FIG. 2B, FIG. 3 exemplarily shows the network access procedure provided by the embodiment of the present application.

When the wireless local area network access device needs to reduce the wireless signal transmission power, so that the terminal closer to the wireless local area network access device accesses the network in an encrypted manner, the first access instruction may be submitted in the manner described in the foregoing embodiment. The processor in the WLAN access device causes the processor in the WLAN access device to perform the following processes:

In S310, according to the first access instruction, the transmit power of the wireless signal is decreased, and the transmit power of the reduced wireless signal is lower than a set value; the first access command is used to indicate that the wireless access device cancels Access verification for the terminal.

In a specific implementation, in some embodiments, the wireless local area network access device may switch to the first working mode according to the first access instruction, and in the first working mode, the transmit power of the wireless signal is reduced to be lower than the Set value. For example, when the WLAN access device works in the second working mode, if the first access command is received, the second working mode is switched to the first working mode, and the transmitting power of the wireless signal (Wi-Fi signal) is from The second power is reduced to a first transmit power, the first transmit power being below the set value.

In S320, after the wireless signal transmission power of the wireless local area network access device is reduced, the to-be-accessed terminal within the coverage of the wireless signal can receive the wireless signal sent by the wireless local area network access device, and can be based on the service set carried therein. A Service Set Identifier (SSID) sends a network access request to the WLAN access device, where the SSID of the WLAN access device and the identification information of the terminal may be carried. Since the transmission power of the wireless local area network access device is reduced, the wireless signal coverage is reduced, and the wireless signal transmitted by the wireless local area network can only be found by the terminal in the adjacent space, and the remote terminal cannot detect the wireless local area network access device. After the processor in the WLAN access device receives the network access request sent by the terminal, if it is confirmed that the SSID carried in the WLAN is the SSID of the WLAN access device itself, the terminal accesses the network, and the privilege is released according to the situation. (such as Internet access). Further, the wireless local area network access device may add the identification information of the terminal to the authorized terminal list (ie, white list) of the wireless local area network access device. Optionally, the identifier information of the terminal may include one or any combination of the following: a physical address of the terminal, and fingerprint information of the terminal, where the physical address of the terminal may include a Media Access Control (MAC) address.

Optionally, when the terminal is connected to the network in an encryption-free manner, when the normal operation of the WLAN access device needs to be restored, the second access command may be submitted to the WLAN access device in the manner described in the foregoing embodiment. The processor in the wireless local area network access device performs the following process: in S330, according to the second access instruction, increasing the transmit power of the wireless signal, and the transmitted power of the added wireless signal is not lower than The set value is used to indicate that the wireless access device resumes access verification for the terminal.
