Hello everyone, Lin Fei to answer the above questions, the router without a password how to change the wifi password, crack the trackless route password many people do not know, now let's take a look!

Cracking the wireless router password is not easy, so do you want to get a way to crack the wireless router password? The following is to introduce the password cracking method of wireless router. Interested friends can have a look!

Cracking principle:

In theory, we set up a NETGEAR wireless router through WEB, and the default password is also based on web page access and management. If we change this default password and turn on WEP or WPA encryption, generally speaking, illegal users should not be able to connect to the wireless network properly. But we can use the telnet command and the NETGEAR default telnet administrative password to connect to the wireless router and change the authentication password of the web page by changing the password command to crack the wireless router password.

Take a Lenovo Zhaoyang E310 notebook and a WGR614 wireless router as an example. The tool used here is telnetenable applet.

Introduction to Telnet:

Software version: 1.0

Language: English version

Software type: free software

Software size: 624 KB

Applicable platform: windows 2000/xp/2003

Download address: telnetenable download

This paper introduces the whole process of password cracking method of wireless router.

Since the default administrative IP address for NETGEAR WGR614 devices is 192.168.1.1, we still use this address to crack.

Step 1: download telnetenable Mini Program, extract it to the root directory of disk c, and make sure that there is a program called telnetenable in the root directory of disk c.

Step 2: check the connection to the NETGEAR WGR61 device through the ping command in the notebook, such as ping 192.168.1.1. If you can ping the general rules, please continue with the following.

Step 3: we can get the MAC address of the Netgear WGR614 device through ping. Looking at the MAC information obtained by the current system through the arp-a parameter, we can clearly see that the corresponding address of 192.168.1.1 is 00-14-6c-ab-cd-ef.

Step 4: after obtaining the MAC address of the device, we can realize the intrusion operation through telnetenable, enter the root directory of disk c, and execute "telnetenable.exe device IP address device MAC address Gearguy Geardog". In this example, the command "telnet enable. Exe 192. 168. 1. 1 00146 c abcdef gear guy gear dog" is used to turn on the telnet function of the NETGEAR WGR614 device.

Step 5: the interface will not return any information. We enter telnet 192.168.1.1 directly and log in to the Netgear WGR614 device remotely over the network.

Step 6: next, you will see a login prompt appears. It seems that we have successfully connected to the NETGEAR WGR614 device. You can successfully log in to the administrative interface by entering the user name Gearguy and password Geardog. This interface supports many commands, which can be viewed through the help command, including bridge (bridging command), ddns (dynamic domain name resolution command), ip (setting IP information), lan (setting LAN parameters), nat (setting NAT information), passwd (changing account password), reboot (restarting the router), save (saving settings), show (.

Step 7: after telnet connection, we enter the WEB command, enter, and enter the page parameter setting interface.

Step 8: in the page parameter setting interface, we only have two commands to choose from, one is passwd, the other is username. Select the account name through the user name, and passwd changes the password corresponding to the account. For example, the author changes the password of the admin account to thisisthepass.

Step 9: finally, use the save command to save the modified settings.

Step 10: after exiting telnet, we can access the management address of the NETGEAR WGR614 device 192.168.1.1 through the IE browser and log in through the admin account and thisisthepass password. The next operation is the same as our usual settings, you can modify all the information and parameters of the wireless router.

At the end of this article, I hope it will be helpful to you.
