If you connect the ISP's cable to the LAN port, the Internet will not work, and the router will not be able to connect to the global network.

After supplying power and connection WAN-Wait for the cable. 30-60 At this time, the router system loads, checks file integrity and initializes network interfaces. Status indicator will start flashing, which means the process of searching for the network or waiting for the setup.

Now your smartphone is ready to communicate with the router, so make sure you're in close proximity to the device so that the signal level is as high as possible, and this will eliminate errors in the initial configuration data transmission.

Installation and launch of the Mi WiFi application

To manage the router Xiaomi 4A is officially recommended to use a specialized application Mi WiFi (also known as Mi Router).It can be downloaded for free from the Google Play Store for Android or Apple App Store for iOS. Sometimes depending on the region, the application may be called Xiaomi Home, but for deep configuration routers it is better to find a profile utility with an icon in the form of a router.

Once installed, launch the app. It will ask for a number of permissions that can't be ignored, and in particular, to work with Wi-Fi on Android, you need access to geolocation, because scanning wireless networks equates the system to determining location.

Connecting to the router network and authorization

The next step is to connect the smartphone to the router's temporary Wi-Fi network. by default Xiaomi 4A Distributes an open network with the name indicated on the sticker (usually Xiaomi_xxxx). The app will tell you to connect to it, OK, and the phone can tell you that there is no Internet access on the network, and ask if you should switch to mobile Internet, and you should answer that question in the negative or choose "Stay connected", otherwise the setup process will stop.

Xiaomi Mi Router 4A is a dual-band device, but in basic settings it often suggests combining 2.4 GHz and 5 GHz networks under one name (Dual-Band function).

The app will suggest creating an administrator password. Write it down or save it to the password manager. Without it, you can't change your settings in the future or reset your router remotely. The 192.168.31.1 or miwifi.com domain is used to log in to the web interface (if you need it through your browser).

Also make sure the provider doesn't use the binding on the patch cord. MAC-In that case, you either have to clone. MAC-address of the old router (if such option is available), or call the provider to reset the link.

In case you forget your administrator password, resetting to factory settings will help. There's a Reset hole on the back. Press it with a paper clip and hold it for about 10 seconds until the indicator flashes orange. The router returns to factory settings, and you can set it up again.
