Step by step teach you how to configure Wireless Router Security

I believe that many users have some knowledge about the security settings of wireless routers. This article focuses on this aspect and gives a comprehensive explanation. Compared with wired networks, wireless networks allow us to get rid of the limitations of cables and bring us great convenience. At the same time, we must also consider that if we do not add any settings, we should be within a certain range of coverage, wireless Networks are open to anyone. On the one hand, strangers may easily access their networks and use our bandwidth. On the other hand, they may cause information leakage. Today, let's take a look at the security configuration of the wireless router.

Let's start with wireless routers. There are many brands of wireless routers on the market. The login methods for different brands of wireless routers may be slightly different. These are described in their respective manuals, if you lose the manual, you can download an electronic manual on the official website of the wireless router. OK. Now let's log on to the wireless router. In this article, I will take a lot of LinkSys Wireless routers on the market as an example to see the wireless router security settings.

The LinkSys Wireless Router uses a smart Wizard to set up a wireless router to help you. Therefore, many friends may not know how many IP addresses they have configured, but even the IP addresses of the wireless router. Here is a simple method to obtain this information. In most cases, the Windows operating system is used. You can open a command line window (Dos window) and input ipconfig to display all the information you need. The Default Gateway you see is usually the IP address of the wireless router. In this example, it is "192.168.8.1 ". The default gateway is the place where all data destined for the Internet goes through.

Logon page

Find the default gateway address, open a web browser, and enter the address in the address bar. The LinkSys vro logon page displays a window prompting you to enter your username and password. The login interface of Some routers is a web page with a user name and password input box. Note: Security Rule 1: Make sure to change the default password of the wireless router, which is usually admin or empty. If you do not modify the settings, all of the following security settings may be in vain. If this router is used for the first time from the box, a setting wizard may be provided to help you set the security of the wireless router. As this article focuses on security settings, we will not elaborate on this. We assume that the wireless router security settings have been completed and are in use.

Wireless Router Security Setting Mode Interface

Because we are concerned about the Wireless router security settings, let's directly click the Wireless tab in the Wireless router configuration interface, and then find the Wireless security (Wireless Security) setting options. By default, security mode is generally disabled. Click the drop-down box to view multiple options. Of course, not all wireless router security modes are the same as the options in our example. Some options may be multiple points, and some may be less. I will take a look at the four options here with you.

WPA-Preshared key

WPA-Preshared key (WPS-PSK): WiFi Protected Access is a very safe way to secure your data. Through its encryption, each data packet transmitted between your wireless router and your wireless network adapter will be packaged and encapsulated by a different key. This means that even if someone intercepts your data packets and cracks the encrypted string, they cannot read other data parts. Because the same encrypted string duplication is unlikely. Now some of the latest wireless routers have started to use WPA2, which upgrades the encryption key from 24 bits to 48 bits. It is impossible to copy a key. In this safe mode, the Preshared key indicates that you set a password for the authorized users. After they enter the password, their devices process other security operations. I personally suggest that you use phrases related to your own password, and it is best to include spaces and punctuation characters in this phrase. The longer the password length, the less likely it will be to be guessed by others.

The AES encryption algorithm is recommended by the author, because AES uses 128-bit, 192-bit, and 256-bit keys to obtain the best security. Some wireless routers allow you to select the length of the key. This LinkSys Wireless Router does not have a 256-bit standard by default. TKIP is not an encryption algorithm, but a "Key Exchange" protocol. Although it is safe, it is not as strong as AES and will reduce the connection speed because it will put an extra burden on the processor. TKIP is a software-based protocol, while AES is hardware-based.
