How to use the Win7 system to reverse the network

By default, the wireless network settings must be configured for the SSID (wireless network name), many people will use the default names such as D-Link, Linksys, DD-WRT, even if With the modification, the SSID is also composed of letters and numbers.

However, even if the SSID consisting of letters and numbers is not set to “broadcast”, the intruder can scan the corresponding wireless network and successfully invade through tools such as bt3, bt4, and network ants. Only by modifying the SSID information to Chinese can the above problems be completely avoided. The reason is that Chinese characters are garbled in these softwares on the one hand; on the other hand, because many intrusion tools are developed by foreign developers, they are not supported by Chinese and are not compatible.

There are some devices in the market that fully support Chinese SSID, but there are still many devices that do not support Chinese to name SSID. In this case, there are two ways to solve this problem:

1. Browser method device requirements: The device requirements are relatively low. Even if third-party firmware such as DD-WAT or Tomato is not used for the wireless router, this method can be used to modify the SSID to Chinese.

Step 1: Since many wireless router management interfaces are created by JSP or JAVA programs, the device's restrictions on Chinese SSID can be removed by disabling JAVA components. Since IE browser has no related features by default, it can only be solved by using Firefox browser. First, access the wireless router calendar interface through the Firefox browser. By default, garbled characters will appear.

Step 2: In the Firefox browser's "character encoding", set the language to "Chinese" to solve the garbled problem. Also uncheck the option to enable javascript” in the Firefox browser.

Step 3: Refresh the management page, enter the Chinese SSID information again, and the prompt “Illegal ASCII code” will not appear.

Step 4: After saving, through the wireless scanning function of the operating system, (no wireless?{:3_60:}) can see the wireless network with the SSID modified to Chinese characters. After the setup is complete, re-check the "Enable javascript" option in the Firefox browser to avoid being affected when browsing other pages in the future. If you don't want to install Firefox, you can use the second method

2.telnet method

This method requires the wireless router to open the Telent service, but not all wireless The device is enabled by default. You need to make sure that the service is enabled before proceeding. The first step: Under normal circumstances, wireless routers that have third-party firmware such as DD-WAT or Tomato will open the Telnet function by default, and some D-Link and Linksys wireless routers have related functions. Just enter the “Telnet wireless router management address” through the prompt window and check it. If the prompt for entering the user name and password appears, it indicates that the function has been enabled.

Tip: The username entered in the Telnet state will always be root, and the password will be the same as the account password in the graphical management interface.

Step 2: After entering the wireless router command line management interface through Telnet, you can set a Chinese SSID by using the nvram set wl_SSID="SSID name" command.

Step 3: After the modification, you can view the changes of the SSID information in real time through the graphical management interface, but there will be garbled characters, you can ignore it.

Step 4: Next, use the nvram commit command to save the settings in the command line management interface, and finally restart with the reroot command.
