Let’s look at a step-by-step algorithm to ensure that your network is as secure as possible.
Preparing for changes in security settings
Before you start changing your password directly, you need to make sure your control device (laptop, tablet or phone) is connected to the Xiaomi router. 4A It's best to use a wired connection through LAN-port for stability, although Wi-Fi settings are also possible if you know the current password.Make sure the indicators on the router's housing are on with a steady light, signaling the normal operation of the system.
You'll need to know. IP-The gateway address, which is the default for Xiaomi devices, is most often 192.168.31.1 or the domain name miwifi.com. If you have previously changed the address of the local network, use current data. Also prepare a piece of paper or text file to write down a new complex password you plan to set so you don’t lose access to the network.
It is important to understand the difference between an administrator password (to log into your router settings) and a Wi-Fi password (to connect devices to the network). In the Xiaomi interface, these parameters can be combined or separated depending on the firmware version. We will change the wireless key, but it may also require updating the login password to protect the admin panel itself.
⚠️ Note: If you change your Wi-Fi password while on a wireless network, your device will instantly lose connection to the router immediately after saving the settings. You will need to re-locate your network in the list of available and enter a new key.

In case the standard address does not open, check the settings of your computer's network adapter. IP-address (DHCP). Also try using miwifi.com, which is often more stable if the system is correctly spelled out. DNS-servers of the provider or the router itself.
What to do if the administrator password is forgotten?
Step-by-step password change through the browser

It is recommended to use the type of encryption WPA2-PSK or WPA3, if your devices support the new standard. This will ensure reliable data protection. Do not use the outdated WEP protocol, as it is broken in minutes. After entering a new password, be sure to click the "Save" or "OK" button at the bottom of the page.

Recommendations for creating a strong password
The security of your home network depends on the complexity of the password you choose. Simple combinations like "12345678," "password," or date of birth are easily matched by automatic bruteforest software in seconds. For the Xiaomi 4A router, which is the gateway to your entire digital home, this is critical.
The ideal password should contain at least 12 characters. Use a combination of capital and lowercase letters of the Latin alphabet, numbers and special characters (for example, @, #, $,!). Avoid using dictionary words or names, as they are the first to be found in hacker attacks.
It's good practice to use passwords, take a base from a favorite song or quote, and use the first letters of the words, adding numbers and symbols. For example, a phrase like "I like to drink coffee at 8am!" can turn into a password called Ylpkv8u!. This password is easy for a person to remember, but extremely difficult for a machine to pick up.
| Symbol type | Examples | Recommendation | Safety impact |
|---|---|---|---|
| Capital letters | A, B, X, Z | Use 2-3 units. | High. |
| Line letters | a, b, x, z | Password basis | Average. |
| Figures | 0-9 | Insert in the middle | Average. |
| Special symbols | !, @, #, $ | I'll bet you 1-2. | Critical |

Users also complain that when they change their password, some older devices (such as older printers or security cameras) stop connecting, which is normal because they remember the old key, and you have to reconfigure each device manually by entering a new password in their interfaces or through pairing buttons.
