Description

Technical Field

[0001] The present invention relates to the technical field of routers, and in particular to a network connection method, device and computer-readable storage medium for visitors. Background Art

[0002] At present, with the rapid development of smart home and Internet of Things technology, wireless network has become an indispensable part of our lives. When there are guests at home who need to use the network but do not want to share the Wi-Fi password, common solutions include enabling guest Wi-Fi through a fixed network page or using WPS (Wi-Fi Protected Setup) for one-click direct connection. However, WPS technology has obvious security flaws, and enabling guest Wi-Fi through the Web UI page is too cumbersome. Specifically, on the one hand, there are some significant defects of WPS: first, the PIN code of WPS is 8 digits. Although the number of combinations is huge in theory, in fact, attackers can use specific algorithms to significantly reduce the number of attempts, thereby cracking the PIN code in a shorter time and obtaining the encryption key of the wireless network, which poses a threat to network security. Secondly, family members or visitors may accidentally press the WPS button, which may cause unauthorized devices to connect to the network, thereby accessing sensitive information or conducting malicious activities, which will expose the privacy of the home shared network and lead to the loss of personal privacy data. Finally, the success rate and speed of WPS connection are not satisfactory, and there are many devices that do not support the WPS function. On the other hand, there are some significant defects in enabling guest Wi-Fi through the web page: first, the process of web page activation is quite cumbersome, and you need to enter a specific domain name or IP address to enter the Web UI, and then enter the login password to configure the guest Wi-Fi page. For the elderly or children at home, such operations may be too complicated, and the login password of the router is also easy to leak, which may lead to more serious personal information security issues.

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0047] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0048] Figure 1 This embodiment provides a visitor's network connection method, which is applied to a router, and the Wi-Fi security protection setting button of the router is reconfigured as a visitor's network control button, and the method includes:

[0049] S1. Turn on the guest connection mode according to the first trigger signal of the network control button;

[0050] S2. When the guest connection mode is on, if the guest device scans a preset identification code, the guest device is allowed to access a guest network corresponding to the identification code;

[0051] S3, closing the guest connection mode according to the second trigger signal of the network control button;

[0052] S4. When the guest connection mode is in the closed state, if the guest device scans the identification code, the guest device is prohibited from accessing the guest network.

[0053] In this embodiment, in order to ensure the security of access, the original WPS function of the router is disabled to prevent security loopholes that may be caused by its connection mechanism.

[0054] In this embodiment, the SSID name and password of the newly added guest connection mode are written during factory production through corresponding writing software commands. For example, first, the factory's equipment tools generate the SSID and password of the guest connection mode according to customized rules, and generate the corresponding QR code. Then, the SSID and password of the guest connection mode are written into the router device through software commands, and at the same time, the corresponding QR code is affixed to the body of the router.

[0055] In this embodiment, the WPS button on the router is modified to a guest connection mode button, and the PIN corresponding to the button is configured as an interrupt mode. Based on this, the application layer of the router captures the pressing and lifting actions of the button by monitoring the touch events of the button. For example, when the user presses and holds this button for 2 seconds, it first determines whether the guest connection mode is enabled. If it is enabled, the shutdown operation is performed, and if it is not enabled, the guest connection mode is started. Further, in this embodiment, when the guest connection mode is turned on, the SSID is synchronously set to a hidden state. At the same time, the router will detect the user access status in the guest connection mode at preset time intervals (for example, one minute, two minutes, etc.). If no user access is detected for a preset number of consecutive times (for example, ten times, twenty times, etc.), the guest connection mode is actively closed.

[0056] Please refer to Figure 2 In this embodiment, the specific connection steps include:

[0057] S10, during the production phase of the routing device, write the SSID and password of the guest WiFi to the cloud database of the routing device through a command;

[0058] S20, generating a QR code according to the SSID and password of the guest's WiFi, printing it, and attaching it to the body of the routing device, so that the guest can scan the code with his or her own mobile device;

[0059] S30, before the guest's own mobile device scans the code, the SSID and password of the guest WiFi written by the above production line are read from the cloud database of the routing device and entered as the current guest WiFi login information;

[0060] S40, the user (household owner or guest) turns on / off the button corresponding to the guest WiFi (i.e., the original WPS button of the routing device);

[0061] S50, the button will report the event to the guest WiFi through an interrupt;

[0062] S60, when the event is reported to the guest WiFi, after determining that the connection mode is turned on, the LED of the routing device is controlled to indicate light;

[0063] S70, when the guest's own mobile device scans the code, the SSID and password of the guest's WiFi are directly verified through the above connection mode;

[0064] S80, if the verification is successful, it is determined that the guest WiFi connection is successful. Further, when the guest connection mode is not needed, long press the button to close the guest connection mode.

[0065] It can be seen that in this embodiment, the guest connection mode can be turned on with one click, providing users with a wireless network quick access solution that does not require complicated operations and password input. Compared with the traditional WPS connection method, the above solution has higher security and convenience, and can effectively prevent the risk of password leakage and illegal access, while providing users with an excellent wireless Internet experience.

[0066] The beneficial effect of this embodiment is that, by turning on the guest connection mode according to the first trigger signal of the network control button; when the guest connection mode is in the turned-on state, if the guest device scans the preset identification code, the guest device is allowed to access the guest network corresponding to the identification code; according to the second trigger signal of the network control button, the guest connection mode is turned off; when the guest connection mode is in the turned-off state, if the guest device scans the identification code, the guest device is prohibited from accessing the guest network. An efficient and convenient guest network access solution is realized, which reduces the complexity of guest access to the network, improves the access security of the guest network, and enhances the user's network experience.

[0067] In this embodiment, both the first trigger signal and the second trigger signal are long press signals; the opening of the guest connection mode according to the first trigger signal of the network control button further includes: when the guest connection mode is currently in the off state, the received long press signal is used as the first trigger signal; the closing of the guest connection mode according to the second trigger signal of the network control button further includes: when the guest connection mode is currently in the on state, the received long press signal is used as the second trigger signal. Thus, through the above one-button operation, not only the connection process is simplified, but also anyone other than the owner can operate safely, effectively avoiding the risk of password leakage.

[0068] In this embodiment, the step of turning on the guest connection mode according to the first trigger signal of the network control button further includes: indicating that the guest connection mode is in the turned-on state through a strobe indicator light signal of the first color or the second color; the step of turning off the guest connection mode according to the second trigger signal of the network control button further includes: indicating that the guest connection mode is in the turned-off state through a constant indicator light signal of the first color or the second color; wherein the constant indicator light signal of the first color indicates that the current network is in a normal state, and the constant indicator light signal of the second color indicates that the current network is in an abnormal state; the step of allowing the guest device to access the guest network corresponding to the identification code further includes: indicating that the guest device has accessed the guest network through the constant indicator light signals of the first color and the second color. For example, in order to more effectively indicate the state of the guest connection mode to the user, the present embodiment uses the only two-color LED light on the router (for example, the light supports red, indicating no network state, and green, indicating normal network state) to display status information at different stages. The specific rules are as follows: First, when the user activates the guest connection mode by pressing a button, the LED light will flash green or red at a frequency of 2HZ; second, after the guest connection mode is successfully activated, the red and green LED lights will remain on at the same time (at this time, the mixed display color is orange); third, when the user turns off the guest connection mode, the LED light will return to its original state, that is, the red light will be on when there is no network, and the green light will be on when the network is normal. As a result, the process of turning on, off, and accessing the guest connection mode is more intuitive, reducing the difficulty of operation.

[0069] In this embodiment, the step of enabling the guest connection mode according to the first trigger signal of the network control button further includes: when the guest connection mode is enabled, configuring the service set identifier of the guest network to be hidden, so as to avoid security issues caused by being in the guest connection mode for a long time.

[0070] In this embodiment, when the guest connection mode is on, if the guest device scans for a preset identification code, the guest device is allowed to access the guest network corresponding to the identification code, further comprising: when the guest connection mode is on, if the guest device scans for a preset identification code, a connection request from the guest device is received; and the guest device is allowed to access the guest network according to the connection request. Among them, the one-click connection guest Wi-Fi technology can directly turn on / off the guest Wi-Fi by pressing a button, and the router of this embodiment is combined with the above-mentioned connection request and directly connected through Wi-Fi Easy Connect technology, which is more convenient and quick. Furthermore, this embodiment can also be combined with relevant access control policies to limit the access scope and permissions of the guest connection mode network, thereby further improving network security.

[0071] In this embodiment, when the guest connection mode is turned on, if the guest device scans for a preset identification code, the guest device is allowed to access the guest network corresponding to the identification code, further comprising: detecting whether the connection request is received at a preset frequency; if the connection request is not received within a preset number of detections, the guest connection mode is turned off. Thus, the guest connection mode can be turned on and off adaptively based on one-click, solving the problem that some mobile phones or devices do not support the WPS function and cannot directly connect to the router Wi-Fi.

[0072] In this embodiment, the identification code is attached to the shell surface of the router; wherein the identification code includes connection verification information corresponding to the guest network; the connection verification information is preset in the router so that the router verifies the received connection request according to the connection verification information.

[0073] In this embodiment, unlike the above-mentioned solution, the identification code is displayed on the display screen of the host device that has been connected to the router; wherein the identification code includes connection verification information corresponding to the guest network; the connection verification information is transmitted to the router so that the router verifies the received connection request according to the connection verification information.

[0074] Furthermore, in this embodiment, when the management device connected to the router opens the Web UI page, it supports configuration of the guest Wi-Fi, including Mac address filtering, encryption method, speed limit, etc. Among them, the default encryption method is WPA2 / WPA3, and when an unchangeable QR code is attached to the router body, the SSID, password, and whether to hide the guest Wi-Fi settings are prohibited from being modified, while when a dynamic QR code is displayed on the display screen of other access devices or management devices, the SSID, password, and whether to hide the guest Wi-Fi settings are allowed to be modified.

[0075] In this embodiment, to ensure network security and prevent the connected users of the guest Wi-Fi from accessing other shared resources in the network, this embodiment strictly sets firewall rules according to the following steps:

[0076] First, the router is configured as follows:

[0077] VLAN 1: Dedicated to local area network (LAN) devices, with an IP address range of 192.168.1.0 / 24.

[0078] VLAN 2: Dedicated to guest Wi-Fi, its IP address range is 192.168.2.0 / 24.

[0079] External Internet interface: eth0 (assumed to be connected to an external network).

[0080] Internal network interface: eth1 (the interface connecting VLAN 1 and VLAN 2).

[0081] This ensures that devices in VLAN 2 (i.e., guest Wi-Fi) can only access the Internet and cannot access any devices in VLAN 1 (LAN).

[0082] Next, configure the network interface and VLAN, and ensure that the interfaces of VLAN 1 and VLAN 2 are correctly configured. Assume that eth0 is the physical network interface, and eth0.1 and eth0.2 are the virtual interfaces of VLAN 1 and VLAN 2. Based on this, the router is configured as follows:

[0083]

[0084] (3) Allow VLAN 1 and VLAN 2 to access the external Internet

[0085]

[0086]

[0087] (4) Prevent VLAN 2 from accessing VLAN 1 resources

[0088]

[0089] Therefore, while enhancing security, it can also effectively prevent the risk of security vulnerabilities in WPS and improve operational convenience.

[0090] Based on the above embodiments, the present invention further proposes a network connection device for a visitor, the device comprising a network control module 10 and a visitor connection module 20, wherein:

[0091] The network control module 10 is used to start the visitor connection mode according to the received first trigger signal;

[0092] The guest connection module 20 is used to allow the guest device to access the guest network corresponding to the identification code if the guest device scans the preset identification code when the guest connection mode is turned on;

[0093] The network control module 10 is further configured to close the guest connection mode according to the received second trigger signal;

[0094] The guest connection module 20 is further configured to, when the guest connection mode is in an off state, prohibit the guest device from accessing the guest network if the guest device scans the identification code.
