[0036] With reference to the drawings and specific embodiments, the present application will be further described. It should be noted that the embodiments and features in the present application can be combined with each other without conflict.

[0037] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0038] With reference to the drawings and specific embodiments, the present application will be further described. It should be noted that the embodiments and features in the present application can be combined with each other without conflict.

[0039] A wireless network troubleshooting method, as shown in the figure, comprises the following steps. Figure 1

[0040] Step S1: reporting information to the network fault detection platform 2 through the access point 1;

[0041] Step S2: the network fault detection platform 2 receives and analyzes whether the information reported by the access point 1 is lower than the set threshold value, if yes, it is judged that the access point 1 is a fault access point, and step S3 is executed, if not, it returns to step S1;

[0042] Step S3: the network fault detection platform 2 selects the nearest and optimal access point 1 to create a simulation terminal according to the neighbor information of the fault access point;

[0043] Step S4: the network fault detection platform 2 issues network instructions to the simulation terminal, the simulation terminal executes the network instructions and returns the processing results to the network fault detection platform 2, and the network fault detection platform 2 analyzes the problem of the fault access point according to the returned results.

[0044] Specifically, the present application provides a wireless network troubleshooting method, which actively reports information through the access point 1, and the network fault detection platform 2 receives and analyzes in real time, realizes comprehensive intelligent monitoring, does not need manual detection, has high troubleshooting efficiency, and improves the stability and reliability of the network.

[0045] In a more preferred embodiment, the information reported by the access point 1 in steps S1 and S2 comprises the association success rate of the wireless client 4 and the packet loss rate of the access point 1.

[0046] Specifically, the access point 1 actively reports information, so that the network fault detection platform 2 can obtain network operation state data in real time.

[0047] ​Compared with manual detection, the active reporting mechanism avoids the limitations of manual troubleshooting, reduces the time cost of detection, ensures that the network status can be monitored in a timely manner, improves the timeliness of fault discovery, and thus improves overall troubleshooting efficiency.

[0048] The association success rate of wireless client 4 and the packet loss rate of access point 1 are important indicators of wireless network performance. A low association success rate indicates a connection problem with the access point, while a high packet loss rate directly reflects poor network transmission quality. By monitoring these indicators, network fault detection platform 2 can quantitatively assess the operating status of access point 1 and accurately determine whether it is faulty, providing strong data support for subsequent troubleshooting.

[0049] In a preferred embodiment, the network instruction in step S4 includes a ping instruction and an http request instruction. When the simulated terminal executes the ping instruction, the packet loss rate is returned, and when the simulated terminal executes the http request instruction, the transmission rate is returned.

[0050] Specifically, the ping command is used to detect the reachability and stability of the network connection. The returned packet loss rate can intuitively reflect the quality of the network link and determine whether there is any interruption or excessive delay.

[0051] The HTTP request command focuses on the network's transmission rate. The returned upload and download rates can be used to measure the network's data transmission capacity. These two commands work together to detect faulty access points from different angles, helping the network fault detection platform 2 to comprehensively and deeply analyze the cause of the fault.

[0052] In a preferred embodiment, the method further includes step S5, wherein the simulation terminal is stopped, and the simulation terminal and the access point for which the fault processing has been completed are restored to normal working state.

[0053] Specifically, the simulated terminal stops operating after completing its fault detection task, freeing up system resources and preventing interference with normal network operations. Once the fault has been resolved, the faulty access point resumes normal operation, restoring the network to its normal service level, ensuring the continued stable operation of the wireless network and protecting the user's network experience.

[0054] In a preferred embodiment, referring to Figure 2 , step S3 includes,

[0055] Step S31: The network fault detection platform 2 selects the access point 1 closest to the faulty access point based on the neighbor information of the faulty access point and issues a simulated terminal command.

[0056] Step S32, the nearest access point 1 creates a simulated terminal according to the simulated terminal information provided by the network fault detection platform 2;

[0057] The simulated terminal information in step S32 includes basic service set identifier information, encryption information, and radio frequency information that need to be associated.

[0058] Specifically, in step S31, the network fault detection platform 2 selects the access point 1 closest to the faulty access point according to the neighbor information and issues a simulation terminal command, thereby ensuring that the simulation terminal can quickly and closely detect the faulty access point and reducing detection delay.

[0059] In step S32, the nearest access point 1 creates a simulated terminal based on the simulated terminal information provided by the platform. The information includes the basic service set identifier information (BSSID) that needs to be associated, encryption information, and radio frequency information, etc., to ensure that the created simulated terminal can accurately simulate the real wireless client environment and improve the accuracy and reliability of detection.

[0060] A wireless network troubleshooting system, referring to Figure 3 、 Figure 5 、 Figure 6 ,include,

[0061] Multiple access points 1, used for reporting access information;

[0062] The network fault detection platform 2 is connected to the access point 1 and is used to receive and analyze access information. When the access information is lower than a set threshold, the corresponding access point 1 is determined to be a faulty access point.

[0063] The simulation terminal creation module 3 is connected to the network fault detection platform 2 and is used to select the access point 1 closest to the faulty access point and the best access point 1 to create a simulation terminal based on the neighbor information of the faulty access point;

[0064] The network fault detection platform 2 sends a network instruction to the simulation terminal, and the simulation terminal executes the network instruction and returns the processing result to the network fault detection platform 2. The network fault detection platform 2 analyzes the problem of the faulty access point based on the returned result.

[0065] Specifically, the present invention also provides a wireless network troubleshooting system, wherein the network fault detection platform 2 is a Han private detection network mechanism platform. Figure 5 and Figure 6 In the figure, access point 1 is represented by the blue box Ap1-Apn, where the red box represents the faulty access point and the yellow box represents the access point 1 that is closest to the faulty access point and is the best.

[0066] The network fault detection platform 2 sends instructions to the simulated terminal, detecting faulty access points by simulating the terminal's association status and performing ping / http operations. It automatically detects the network environment and abnormal APs without manual intervention, achieving the goal of automatic network detection.

[0067] In a preferred embodiment, referring to Figure 4 , the simulation terminal creation module 3 includes,

[0068] A command generating unit 31 is configured to select the access point 1 closest to the faulty access point according to the neighbor information of the faulty access point and issue a simulated terminal command;

[0069] The terminal creation unit 32 and the connection command generation unit 31 receive the simulation terminal command and create a simulation terminal according to the simulation terminal information through the nearest access point 1.

[0070] Specifically, command generation unit 31 is responsible for selecting an appropriate access point 1 based on the neighbor information of the faulty access point and issuing the simulated terminal command, focusing on the decision-making phase of simulated terminal creation. Terminal creation unit 32 receives the command and creates a simulated terminal based on the simulated terminal information through the nearest access point 1, taking charge of the specific creation operations. This makes the simulated terminal creation process clearer and more efficient, improving the operational efficiency and stability of the entire system.

[0071] The simulation terminal accepts Han network commands, such as ping and https requests. The simulation terminal pings the relevant addresses based on the number and size of ping packets, and returns the ping results such as packet loss rate to the Han network platform. The https request performs speed test based on the download and upload URLs, and returns the https execution results such as upload and download rates to the Han network platform.

[0072] In a preferred embodiment, the system further includes a stop module connected to the simulation terminal, configured to stop the simulation terminal so that the simulation terminal and the access point for which the fault has been processed are restored to normal working state; the simulation terminal is automatically or manually stopped to restore the normal working state;

[0073] It also includes a plurality of wireless clients 4, which are connected to the access points 1 one by one for accessing the wireless network.

[0074] Specifically, multiple access points 1 are responsible for collecting and reporting network information, providing raw data for the system. The network fault detection platform 2 receives and analyzes the information, determines the faulty access point, and works in conjunction with the simulated terminal creation module 3.

[0075] The simulation terminal creation module 3 creates a simulation terminal according to the platform instruction and detects the faulty access point.

[0076] Multiple wireless clients 4 connect to access point 1, simulating real-world network usage scenarios and enabling the system to detect and troubleshoot faults in a realistic operating environment. Each component works together to form a complete wireless network troubleshooting system, enabling efficient network troubleshooting and repair.

[0077] In one embodiment, the client association success rate threshold is set to 80%.

[0078] Under normal circumstances, the success rate of wireless client 4 associating with access point 1 should remain high. If it falls below this threshold, it indicates that there may be problems with the access point when connecting to the client, affecting the user's network access experience.

[0079] The access point packet loss rate threshold is set to 5%. The packet loss rate reflects the proportion of data packets lost during network transmission. Excessively high packet loss rates can seriously affect network stability and data transmission quality. When the packet loss rate exceeds 5%, it indicates a possible network failure.

[0080] At a certain moment, access point 1 reported a client association success rate of 70% and a packet loss rate of 8%. This indicates that during this period, only 70% of wireless clients 4 attempting to connect to access point 1 successfully established connections, and packet loss during data transmission was severe.

[0081] After receiving the information reported by access point 1, network fault detection platform 2 compares it with the set threshold. Since the client association success rate of 70% is lower than 80% and the packet loss rate of 8% is higher than 5%, the fault judgment conditions are met. Network fault detection platform 2 determines that access point 1 is a faulty access point.

[0082] Next, in step S3, network fault detection platform 2 selects the closest and most optimal access point (assuming it's access point Ap3) based on access point 1's neighbor information to create a simulated terminal. The "optimal" factor takes into account factors such as signal strength and load. Access point 1 with a strong signal and low load is selected as the target for simulated terminal creation.

[0083] Then, step S4 is executed, where the network fault detection platform 2 sends network instructions, such as ping instructions and http request instructions, to the created simulation terminal.

[0084] The simulated terminal executes the ping command. Assuming that the number of ping packets is 100 and the packet size is 32 bytes, the relevant addresses of the faulty access point are pinged. The returned packet loss rate is 15%;

[0085] Execute the http request instruction to perform download and upload tests on the specified test URL. The returned download rate is 5Mbps and the upload rate is 1Mbps.

[0086] Network fault detection platform 2 further analyzes the problem with access point 1 based on the processing results returned by the simulated terminal. The returned packet loss rate and transmission rate indicate that access point 1 may be experiencing signal interference, hardware failure, or network congestion. Appropriate measures, such as adjusting the channel, restarting the device, or upgrading the hardware, are then taken to resolve the problem and ensure normal operation of the wireless network.

[0087] The above description is only a preferred embodiment of the present invention and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
