Retrieval of wireless passwords (1)

With the popularization of wireless networks, more and more home users have wireless routers and wireless network cards. The combination of wireless devices allows us to leave the network cable at any location at home, enjoy surfing anytime, anywhere. However, in actual use, some common users often forget one or another password. Can the remote and local passwords of wireless routers and WEP encryption be retrieved in some ways? The answer is yes. Today we will learn more about the retrieval of wireless passwords.

1. Which wireless passwords will be lost or forgotten:

Generally, the wireless network of a home user is composed of a wireless router and a wireless network card. The wireless network card does not have a logon password. You can use it after installing the correct driver. Therefore, the login password is mainly a wireless router. Some users often send me a distress message, claiming that their wireless router login password has been forgotten or changed by hackers.

In addition to the loss of the login password of the wireless router, some readers will also perform WEP or WPA encryption for wireless transmission data to improve wireless network security. The keys used for encryption will also be forgotten, this part also involves the key retrieval problem.

In addition, in many cases, we cannot access the wireless router by setting WEP information on the local computer to connect to the wireless network, in the future, when we want to change or query WEP encrypted information locally, we can only retrieve the password locally, which also involves local WEP Information Retrieval.

Ii. retrieval of the wireless router login password:

If we forget the wireless router login password or the previously set password is tampered with by hackers, we will not be able to log on to the wireless router management interface for any settings and modify parameters. Except for a few manufacturers' wireless routers that have a universal password or logon cracking vulnerability, if the parameter configuration file is not saved before, it is impossible to restore the password while saving the currently set parameters. To log on to the wireless router again, you must clear all the previous configurations. The specific method is as follows.

TIPS:

The author once introduced how to use the wireless router system vulnerability to modify the logon management password of netgear products. Interested readers can search for articles on the IT168 Home Networking channel.

Step 1: place the wireless router in your hands when the power supply is connected, and view the rear panel of the device.

Step 2: in general, we will see a small hole in the rear panel of the device, and there will be a reset-like sign on the top of the hole. This is the reset key. Find a needle (a normal ballpoint pen can also be) directly inserted into the hole, and hold it for 30 seconds to 1 minute and then release it.

Step 3: After completing the above operations, we can use the default password of the wireless router to log on again after power-on, but the original parameter settings will also disappear and the router will return to the factory status. You can obtain the default Administrator account information and password from the product manual.

The following lists the default passwords and accounts of some common wireless routers.

TP-LINK -- username admin, password admin

Digital China-UserName: ADSL, password: ADSL1234

Huawei -- the username and password are both ADMIN

Shida -- username: user password: password or username: root password: grouter

DD-WRT -- username: root Password: admin

MOTO -- username: admin Password: motorola

Emma -- username: admin Password: admin Username: SZIM password: SZIM
