The most complete Wi-Fi password setting guide + fast connection method! Makes you no longer worry about being stunned

When decorating or changing routers, you always have to face a problem: the set password is too simple, it is easy to be cracked by hacking “social workers” or even brute, and then slow down the Internet speed; The guests who are a guest in input too much headache. After all, ordinary website passwords have a variety of mature generation, storage and filling solutions, but the existing method of Wi-Fi passwords that require frequently shared passwords are fundamental.

However, this does not mean that your Wi-Fi password cannot take into account security and convenience. In fact, today’s smart devices usually have various methods, which can ensure that the Wi-Fi password is complicated enough and let your friends and your friends quickly connect to the Wi-Fi network.

▲ Quickly connect to Wi-Fi through the NFC tag. Afterwards, the implementation method will be explained separately

Today, Ai Fan’er started with the most basic settings to teach you how to strengthen your Wi-Fi network security.

Basic settings

If you want to be good, you must first benefit your instrument. If you want to strengthen your Wi-Fi network, you must start with the encryption protocol and password strength.

1. Use WPA2 or WPA3 and other strong encryption protocols

At present, the three mainstream Wi-Fi network encryption methods have wired equivalent encryption (WEP) and Wi-Fi access protection (WPA), of which WPA also iterates to the second and third generation. Although there are currently old devices using weP encryption, it is considered as an unsafe encryption method because it has been found to have serious security vulnerabilities.

Generally speaking, the newly launched Wi-Fi AP (access hotspot) device’s encrypted meditation value is WPA2. If you want to check your Wi-Fi network encryption protocol, you need to modify or view your Wi-Fi AP or wireless router (hereinafter referred to as “Wi-Fi Device”). Here we take the newer TP-Link router as an example:

Connect the device to the network of Wi-Fi device, open the router setting page from the browser

Click “Routing Settings” at the bottom to enter “Wireless Settings”

Find the “Certification Type” on the “Wireless Settings” part on the right to make sure to select “WPA2-PSK / WPA3-SAE”, click to save

▲ The new TP-LINK brand router is modified and authenticated.

Different brands, different models and launching Wi-Fi devices may also be different from the router setting page; the location of the options is different, roughly in “wireless settings”, “broadcast settings”, “AP settings” Essence There are also differences in the types of encryption authentication supported, ensuring that the following certification type is selected:



How to find your Wi-Fi router setting page address?

At present, the default setting page address of most Wi-Fi routers on the market will be one of the following addresses:

You can try to open the above three addresses to see if you can open the login page of your router.

If not, you can check the bottom label of the router, or connect the mobile phone into the corresponding Wi-Fi, and find the Wi-Fi details page in the settings to mark the IP address with “router” or “gateway address” (it is usually 192.168 with 192.168 The probability at the beginning is your router setting the login page address.

In addition, if your router (WAN interface) is connected to the operator’s “light cat” or other gateway/router, these addresses may open the setting page of the upstream network device, please pay attention.

Still trouble? Try to pull out the Wan of the router and connect to this Wi-Fi. The newer router has a network detection function, and it will automatically take you to the router background when we disconnect.

If your Wi-Fi device does not have the above encryption method, it may be older in the firmware. Try to update the firmware (see the Wi-Fi device manual) before setting. If not, it is recommended to consider replacing more modern Wi-Fi devices to ensure network security.

2. Set a strong password

The reason why this one is to put this one after the encryption agreement is because the issue of the password we mentioned next is closely related to the encryption agreement: in 2018, the encryption agreement of WPA2-Personal was also found loopholes. The client connected to the network is “squeezed” offline, waiting for the client to try to connect to the Wi-Fi device again, to crack the password by intercepting the handshake package.

Although this cracking possibility, it does not mean that WPA2-Personal is completely unsafe. Some security handbooks are recommended to set up sufficient irregular characters to avoid this attack method. Of course, a complete irregular password will also cause some obstacles to the device connection in our device. Because of this, the password that is easy to read but meaningless with PSEUDOOWORD can be relatively easy to make us be easier when entering input.

If you have 1Password and choose “Yiji Code” when you create a new password, you can generate a virtual password according to your needs. In addition, there are other passwords on the Internet to generate virtual passwords.

In addition, remember to write down the new password after changing the password.


Even if there are complicated and randomly generated passwords, guests at home do not need to do “eye test” and “typing test”. You only need these tips to connect your Wi-Fi.

1. Use the system built -in sharing function

Including the various systems of Apple, and most of the major domestic models of major domestic Android manufacturers, all have the “Share Wi-Fi Password” option.

Let’s talk about iPhone first. If you and your friends use iPhone and mutual address apps to exchange mobile phone numbers or mailbox addresses in the address book app. At the same time Share function to quickly connect to the Internet.

It’s best to unlock your iPhone first

Let your friends open the “Settings” APP, enter the “Wireless LAN” or “WLAN”, click on your network name, and then wait at the password input interface

At this time, your iPhone will pop up a sharing prompt and click the “Share Password”.

▲ Share the Wi-Fi password through the functions of iOS

As for the Android phones, most of the sharing functions they provide are shared through QR code. Take LineageOS as an example, enter the details of the Wi-Fi network, click the “Share” button to verify the lock screen password to display the Wi-Fi QR code.

▲ Set up sharing Wi-Fi QR code through the system Wi-Fi

It should be noted that this QR code does not seem to be scanned through WeChat. The iPhone can scan the code through the “Camera” APP. Android phones can find the “scanning” function in the system or Wi-Fi settings. If not, then you may need to download the QR code scanner.

2. NFC card

NFC (Near Field Communication, near -field communication) protocol is a protocol that facilitates the data exchange between two mobile phones or mobile phones and other items. At present, most of the models of almost mainstream brands have NFC functions, and we can also use it to make a Wi-Fi connection NFC card. You can connect the Wi-Fi network as long as you touch it.

Back to the renderings of the beginning of the article, let’s talk about its implementation method below.

▲ Quickly connect to Wi-Fi through the NFC tag

First, you need to buy a few blank NFC or RFID cards. Search “NFC Tags” or “NFC Card” on the mainstream e -commerce platform, you can find a lot of blank cards. There are many different styles and colors. The price is usually a few cents (one).

Then, we want to download on the mobile phone

NFC Tools

This app.

With the iOS version and Android version, the Wi-Fi NFC card can be written.

Prepare blank cards and

After that, we can write the Wi-Fi password directly into the blank card:


Select “Writing” by the main interface

Click “Add Record” to find “Wi-Fi Network”

Click “Edit” on the right side of “Identity Verification”, and select the corresponding encryption protocol according to your actual configuration

Fill in your Wi-Fi name (SSID) and password, click OK in the upper right corner

At this time, it will be automatically returned. After the return interface, click the third “writing” button above, and then refuel the blank card on the back of the mobile phone until the mobile phone prompts “Write to complete”

As long as your friend uses an Android phone with NFC function, you can put this card directly on the back of the mobile phone under the premise of turning on the NFC function to directly connect to the back of the phone, and you can directly connect to the Wi-Fi. , No third -party APP. Unfortunately, although the iPhone can use

Making such a card, but the system cannot directly read NFC tags with Wi-Fi information and connect to the network directly.

3. Wi-Fi QR code

Remember the method of sharing the Wi-Fi network that we just said? It only writes the information and passwords of the Wi-Fi network in a specific format into a QR code in a specific format. As long as we master what “specific format” is, we can also generate such a QR code ourselves.

The text format of this type of Wi-Fi network QR code is:

Wifi: t: [encryption mode, wep or wpa]; s: [network name]; p: [network password]; h:;


Wifi: t: wpa; s: mynetwork; p: ​​p455W0rd; h:;

Fill in your network information as required and find a (reliable) QR code generator to generate a Wi-Fi QR code. Use the device that needs to be connected to scan it (for example, using an iPhone camera app) to connect directly.

▲ Scan the Wi-Fi QR code through the iPhone camera APP

It should be noted that if you need to generate such a Wi-Fi QR code, avoid using English segmentation and colonic characters in the password and network name, otherwise the QR code will not be read. In addition, using WeChat to scan this type of QR code cannot be directly connected to the network.

4. Direct manual input

When encountering equipment such as Kindle and Nintendo Switch that cannot scan code or (free) NFC functions, what we can do is to enter the password manually. Fortunately, this kind of device does not need to frequently connect different Wi-Fi networks in our daily use, so it is relatively harmless.

This also refers to the reason why AppSo recommends the use of virtual word passwords: When encountering the situation of the first network of such devices, a completely random password will definitely destroy your good mood for a day (don’t ask me how to know) …

In addition, there are also a tips: most of these devices are now equipped with the “display password” function. In the case of ensuring privacy, this can reduce many burdens for your password input work.

▲ Nintendo’s Switch’s “View Password” function is above the keyboard

Due to space restrictions, we only discuss the security practice of WLAN hotspot encryption mode, Wi-Fi password settings, and how to save time and energy to enter complex Wi-Fi passwords while ensuring strong security.

In addition to the password, there are many places that can be investigated in the security practice of Wi-Fi. If you understand these practice, you are also welcome to go to the message area to tell you.
