3. Setting up the router for the first time: logging into the web interface and basic settings

After physically connecting, you need to configure the router via the web interface or mobile app. Let's look at both options.

Method 1: Configuration via the web interface (recommended for PC):

1. Open your browser (Chrome, Firefox, Edge) and enter in the address bar 192.168.31.1 or miwifi.com.
2. Enter your username and password to log in. By default, this is admin and the password from the sticker on the router (or admin, if the sticker is missing).
3. The system will prompt you to create a new administrator password. Create a strong one (at least 8 characters, with numbers and letters).

Method 2: Setup via the Mi Wi-Fi app (for smartphones):

1. Download the app Mi Wi-Fi from the App Store or Google Play.
2. Connect to the router's network (if not already connected) and open the app.
3. Click "Add Device" and follow the on-screen instructions. The app will automatically detect the model. AX1800.

After logging in, the system will prompt you to configure Internet connection. Here it is important to correctly specify the parameters from the provider:

• 🔄 If you have Dynamic IP (DHCP) - just click Next.
• 🔐 If PPPoE — enter the login and password from the contract with the provider.
• 📡 If Static IP — specify the IP address, subnet mask, gateway and DNS (this information should be provided by the provider).

After saving the settings, the router will reboot. If you still can't connect to the internet, check the following:

• Correctness of the entered data (especially for PPPoE).
• No MAC address restrictions (see warning block above).
• The condition of the provider's cable (try connecting it directly to the PC).

4. Setting up a Wi-Fi network: name, password, and signal optimization

Now let's move on to setting up the wireless network. By default Xiaomi AX1800 creates two networks: at frequency 2.4 GHz And 5 GHzThey can be combined into one or configured separately.

How to change your Wi-Fi name (SSID) and password:

1. In the web interface, go to Settings → Wi-Fi.
2. In the field Network name (SSID) Enter a new name (eg MyHomeWiFi_5G for 5 GHz network).
3. In the field Password Please enter a new key (we recommend using WPA2-PSK or WPA3).
4. Click "Save." The router will reboot, and you'll need to reconnect.

Optimal settings for a stable signal:

• 📶 Channel: For 2.4 GHz select a channel 1, 6 or 11 (they do not intersect). For 5 GHz use channels 36–48 or 149–165 (less busy).
• 🔄 Channel width: For 5 GHz install 80 MHz (if there are few other networks nearby) or 40 MHz (for stability).
• 🛡️ Security: Turn it off WPS (vulnerable to hacking) and turn it on Protection against password guessing.

If you have smart devices (eg. Xiaomi Mi Home or Amazon Echo), which only work on 2.4 GHz, we recommend:

• Leave the network 2.4 GHz with a separate name (for example, MyHomeWiFi_2G).
• Disable the feature Smart Connect (automatic switching between frequencies), as some devices do not support it.

What is Smart Connect and is it worth using?

Function Smart Connect Automatically connects devices to the optimal frequency (2.4 or 5 GHz) depending on the signal. However, some gadgets (especially smart bulbs or cameras) may lose connection when switching. If you notice problems, disable Smart Connect in the Wi-Fi settings and configure the networks separately.

Important for owners of gaming consoles (PS5, Xbox): enable the mode in the Wi-Fi router settings IGMP Snooping and turn it off Band SteeringThis will reduce latency (ping) and prevent connection drops while playing.
