• 🔧 Screwdriver for fastening the router on the wall (if you need to fix the case).

Important: if you connect to the Internet via PPPoE (for example, from providers Rostelecom or Beeline), check the username and password for authorization from the operator in advance. SMS When the service is activated, without it, the router will not be able to establish a connection!

2. Physical connection of the router

The first step is to connect all the cables correctly, and errors in this step can lead to a lack of Internet or improper Wi-Fi.

Step-by-step:

1. Unpack the router and place it in the selected place. The optimal position is on a hill (for example, on a shelf), in the center of the apartment, away from metal objects and household appliances that create interference (microwaves, wireless phones).
2. Connect the power supply to the router and plug it into the socket. Wait for the blue power indicator to light up (flashing in orange signals an error).
3. Take the internet cable from the provider and paste it into the port WAN (It's usually in blue and signed. Make sure the connector is in the blue. RJ-45 snapped.
4. If you need to connect the device via cable (for example, Smart). TV PC or PC, use any of the ports LAN (yellow-port).

After connecting, wait until the router loads (it will take 1-2 minutes (WAN) should light up blue (if it flashes orange, see Problem Solving").

Accommodation tip: If your apartment has thick walls or multiple rooms, try placing the router closer to the center. AC1200 technology MU-MIMO, But it's less effective when there's obstacles, and avoid placing it near aquariums or mirrors, because water reflects Wi-Fi signals.

3. Set up via the Mi Wi-Fi mobile application

The easiest way to set up a router is to use the official Mi Wi-Fi app (available for Android and iOS), which automatically determines the device model and offers optimal settings.

Instructions for setting:

1. Download the Mi Wi-Fi app from Google Play or the App Store.
2. Connect your smartphone to the router's Wi-Fi network. It's called by default. Xiaomi_XXXX (where XXXX — last-minute MAC-address), the password is indicated on the sticker at the bottom of the case.
3. Launch the application and click Add the device → The router. The app will automatically find it. AC1200.
4. Select the type of Internet connection (usually PPPoE or Dynamic). IP) and enter data from the provider.
5. Give the name of the Wi-Fi network (SSID) and a password. We recommend using WPA2-PSK password not shorter than 8 characters.
6. Wait for the settings to be applied (the router will restart).

If the application does not find the router, check:

• 🔄 Are you connected to your Wi-Fi network (not another network).
• 📱 Have you allowed the app to access the location (required to search for devices).
• 🔌 Are the indicators on the router on fire (if not, check the power supply).

💡

If you have a dual-band router (2.4 GHz + 5 GHz, in the application, you can divide networks by giving them different names (for example, MyWiFi_2G and MyWiFi_5G). This will make it easier to connect devices to the desired frequency.

4. Setup via web interface (for power users)

The router's web interface offers more fine-tuning than a mobile application. DNS, tune in DMZ or turn on the guest network.

How to get into the control panel:

1. Connect your computer to the router via Wi-Fi or cable.
2. Open your browser and type in the address bar 192.168.31.1 (or miwifi.com).
3. Log in. The default login and password is admin (if you haven't changed it).

The main sections of the web interface:

In the section Wireless network can be enabled mode 802.11r (Fast reconnection between access points is useful if you have multiple routers on the same network, but some devices (such as older smartphones) may not support this standard.

5. Selection of mode of operation: router, repeater or access point

Xiaomi AC1200 It supports multiple modes of operation, each of which is suitable for different scenarios.

1. Router Mode (Router Mode)

• 🏠 The basic mode for building a home network. IP-addresses, manages traffic and connects to the Internet independently.
• ⚡ It's fine if AC1200 — the only device in your network.

2. Repeater Mode (Repeater Mode)

• 🔄 It amplifies the signal of another Wi-Fi network (for example, from the router provider), useful if some rooms have a weak signal.
• ⚠️ Internet speeds in this mode are reduced by about 30-50% due to double data transfer.

3. Access point mode (AP Mode)

• 📡 It connects to your existing network via cable and distributes Wi-Fi, which is used if you already have a primary router but need to expand your coverage.
• ✅ It maintains full speed of the Internet (unlike the repeater).

Important: in the repeater mode Xiaomi AC1200 Does not support 5 GHz – only 2.4 GHz. If you need to strengthen the 5 GHz network, use the access point mode with a cable connection.

How to change the regime:

1. Go to the router's web interface (192.168.31.1).
2. Go to the Supplementary → Mode of work.
3. Select the desired mode and save the settings.

By default, the router selects the channel automatically, but this is not always optimal.

• 📱 Use applications like Wi-Fi Analyzer (Android) or NetSpot (iOS/macOS) air-scan.
• 🔢 For the 2.4 GHz band, choose channels 1, 6 or 11 – they don’t overlap.
• 🔝 5GHz channels 36-48 or 149-165 (if supported by your router) are suitable).

Signal power

In the settings of the router (Wireless network) → Additional) Transmission power can be changed. Options:

• 🔋 High – maximum coverage, but more interference from neighboring networks.
• 🔋 Average – balance between range and stability.
• 🔋 Low – Minimal interference but weak signal.

3. Security of the network

Never use outdated encryption standards (WEP or WPA). Optimal settings:

• 🔒 Network authentication: WPA2-PSK (or WPA3, if supported by devices).
• 🔑 Encryption: AES (not TKIP).
• 🔑 Password: at least 12 characters, with numbers and special characters.

We also recommend that you turn off the function. WPS (in the section Wireless network → WPS), It has vulnerabilities and can be hacked in a matter of hours.

💡

If you have many IoT devices (smart light bulbs, sensors), create a separate guest network for them in the router settings, which will protect the main network from potential vulnerabilities of smart gadgets.
