Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Because in the prior art, when the AP activates WPS, the AP starts to check whether the received probe request packet is from multiple STAs, and also detects whether the received probe request packet is received within 120s after the button is pressed. In the 120 time window, if the AP receives a probe request packet sent by multiple STAs, or if UUID-E (universal unique identifier) in an M1 packet received by the AP is different from UUID-E in the probe request, then an "session overlap" error occurs in the AP. At this time, the AP replies a wsc_nack message back the next time it receives the M1-M8 message, thereby reducing the success rate of the connection.
The invention provides a solution, when a wireless access point receives a wireless security fidelity setting detection request broadcast by at least two wireless clients, a target wireless client with the strongest wireless network signal is determined from the at least two wireless clients; and sending wireless security fidelity setting detection response information to the target wireless client so as to enable the target wireless client to establish connection with the wireless access point. According to the scheme, the wireless access point is connected with the wireless client with the strongest signal in the wireless clients corresponding to the received wireless security fidelity setting detection request in an associated mode, so that when a plurality of wireless clients exist simultaneously in a WPS state, interference is avoided in the process of connecting the wireless clients with the wireless access point, and the connection success rate between the wireless clients and the wireless access point is improved.

In this embodiment, if a wireless security fidelity setting probe request broadcast by at least two wireless clients is received, a target wireless client with the strongest wireless network signal is determined from the at least two wireless clients, for example, the signal strength of the first wireless client is-40 dbm, and the signal strength of the second wireless client is-60 dbm, and the first wireless client is determined to be the target access point.
And step S12, sending wireless security fidelity setting detection response information to the target wireless client so as to enable the target wireless client to establish connection with the wireless access point.
In this embodiment, after the wireless security fidelity setting probe response information is sent to the target wireless client, the target wireless client is connected with the wireless access point by WPS through the address information of the wireless access point, so that mutual interference among a plurality of wireless clients is avoided.
The wireless network connection method is used for a wireless access point, and if a wireless security fidelity setting detection request broadcast by at least two wireless clients is received, a target wireless client with the strongest wireless network signal is determined from the at least two wireless clients; and sending wireless security fidelity setting detection response information to the target wireless client so as to enable the target wireless client to establish connection with the wireless access point. And the wireless access point is connected with the wireless client with the strongest signal in the wireless clients corresponding to the received wireless security fidelity setting detection request in an associated mode, so that interference in the connection process of the wireless client and the wireless access point is avoided when a plurality of wireless clients exist simultaneously in the WPS state, and the connection success rate between the wireless client and the wireless access point is improved.
Further, as an alternative embodiment, the step S21 includes:
step S111, if a wireless security fidelity setting detection request broadcast by at least two wireless clients is received, ordering the at least two wireless clients according to the signal intensity from high to low;
in this embodiment, the wireless access point determines all wireless clients sending out the wireless security fidelity setting detection request in the area according to the received wireless security fidelity setting detection request, and sorts the signal strengths of the wireless clients from high to low, for example, the signal strength of the first wireless client is-40 dbm, and the signal strength of the second wireless client is-60 dbm, and then sorts the first wireless client and the second wireless client sequentially according to the sequence.
In general, the signal strength is determined by the distance between the wireless access point and the wireless client, and the closer the distance is, the stronger the signal strength is.
Step S112, determining the first wireless client as the target wireless client.
In this embodiment, the first wireless client is determined as a target wireless client, and a probe response is transmitted to the first wireless client, and the probe response is not transmitted to the remaining wireless clients. Thus, even when a plurality of probe requests transmitted by a plurality of wireless clients are received, only a probe response is transmitted to one of the wireless clients having the strongest signal, and no response is made to the other wireless clients, thereby avoiding mutual interference.
It will be appreciated that there is a case where only a probe request broadcast by one wireless client is received, and as another alternative embodiment, before step S11, the method further includes:
and judging whether wireless security fidelity setting detection requests broadcast by at least two wireless clients are received.
In this embodiment, the number of wireless clients is determined according to the number of wireless clients with different information of the wireless clients in the wireless security fidelity setting probe request broadcast by the wireless client received by the wireless access point, for example, when two wireless security fidelity setting probe requests are received, but the information of the wireless clients in the two wireless security fidelity setting probe requests is the same, it is determined that only one wireless client is received.
Further, the wireless client may periodically broadcast information, and as an optional embodiment, the step of determining whether the wireless security fidelity setting probe request broadcast by at least two wireless clients is received specifically includes:
and judging whether the wireless security fidelity setting detection request broadcast by at least two wireless clients is received within a preset time period.
The preset time period may be shorter than an information broadcasting period of the wireless client. For example, the broadcast period of the wireless client is 180ms, and the preset period may be 120ms.
Specifically, in this embodiment, the wireless access point may determine whether a wireless security fidelity setting probe request broadcasted by at least two wireless clients is received within 120ms, so as to reduce the processing amount of data and improve the efficiency of wireless network connection.
As another alternative embodiment, prior to step S12, the method further includes:
step S113, adding other wireless client information except the target wireless client in at least two wireless clients into a connection blacklist;
specifically, in this embodiment, device information and/or address information of a wireless client corresponding to a received wireless security fidelity setting probe request other than a target wireless client is added to a connection blacklist.
And step S114, sending connection failure information to the wireless clients in the blacklist so that the wireless clients in the blacklist do not establish connection with the wireless access point.
In this embodiment, if an M1-M8 message in a wireless security fidelity setting probe request broadcast by a wireless client in the blacklist is received, wsc_nack information is sent to the wireless client in the blacklist, so that the wireless client in the blacklist and the wireless access point do not establish a connection.
It will be appreciated that the wireless client that joins the blacklist does not establish a connection with the wireless access point only in this connection, and as another alternative embodiment, after step S12, the method further includes:
and clearing the wireless client information in the blacklist.
In this embodiment, after the wireless access point and the wireless client are successfully connected, the wireless client information in the blacklist is deleted, so that when the WPS connection is started next time, connection can be established with other wireless clients.
